🔋 📱❄️🥾🔓, an EL1/EL3 coldboot vulnerability affecting 7 years of LG Android devices

I should probably preface all of this by saying that I'm not really a security professional in the sense that I don't actually do security stuff for a living; I reported this vulnerability in March and gave a 90 day delay on releasing specific details mostly just because that's A Thing That Security Researchers Do. Also the vulnerability doesn't require user interaction from coldboot so it's a bit nasty in that regard. But also this vulnerability sat around for 7 years so it could be argued that, if anything, 90 days is too long.

Anyhow jumping into things, this is a writeup documenting CVE-2020-12753, a bootloader vulnerability affecting most Qualcomm-based LG phones since the Nexus 5, all the way up to the my test device, the LG Stylo 4 Q710 (and 5 Q720), and probably others. While working on the implementation of this vulnerability I thought it was odd how few bootloader vulnerabilities for Android actually get properly documented, and given the sheer spread of affected devices of this particular vuln I thought it'd be interesting to document it in detail.

A Quick Primer on the (Qualcomm) Android Boot Process

The device I'm working with, the Stylo 4, operates on 2013-2016 variant of Qualcomm's boot sequence described at https://lineageos.org/engineering/Qualcomm-Firmware/:

- On power-on, the Primary Bootloader (PBL) initializes DRAM, eMMC, etc and then loads and verifies SBL1 (Secondary Bootloader 1) from eMMC. - SBL1 then loads and verifies the Trusted Execution Environment (TEE), aboot, and a few other bits and pieces and then jumps to the TEE, in this case Qualcomm's Secure Execution Environment (QSEE) - QSEE sets up secure EL3/EL1 (TrustZone) and jumps down to aboot (non-secure EL1) - aboot loads and verifies the Linux kernel and jumps to it

Some Android devices allow "bootloader unlocking", which allows unsigned kernels to be loaded and run. Generally this unlocking occurs via aboot, and the implementation varies from vendor to vendor, however in most cases what happens is that a fastboot command gets sent to the phone to unlock/lock the phone, and as part of Android's Verified Boot, the phone's storage is wiped on this transition. There's also some requirements on user verification so that, in theory, this unlock cannot occur without user interaction.

Additionally, with verified boot enabled, Android will use dm-verity to verify all files on the root/system partition, and SELinux is run as Enforcing.

Variants on the Boot Process, added by LG

In practice, the boot process isn't quite so simple: Vendors are able to add modifications to the boot process as they see fit. In LG's case, these differences can be summarized as follows: - Hardware bringup in SBL for charging PMICs, LEDs, and other misc hardware - Misc logging/debugging modifications - Additional TEE processes for SIM unlocking, backed by RPMB - In aboot, vendor-specific fastboot commands (or no fastboot at all in the case of my device), restrictions on unlocking via certificates, verification modifications, additional boot args for Linux, etc - Vendor-specific recoveries/flashers, LAF in the case of LG

While I initially started in a privesc from within Linux (and got ~close to getting kernel execution), Google has done a lot of work to ensure that vendors can’t mess up Android security. However, bootloaders have a lot less oversight, so going after these vendor-specific bits of hardware bringup seemed extremely opportune for errors.

Introducing: raw_resources

At an undetermined point in time (likely prior to the Nexus 5 releasing), LG added an "imgdata" partition on eMMC to store boot graphics for Download Mode, fastboot graphics, charging graphics, the unlock graphic and so on. Image data is stored RLE compressed and for each image, metadata for the image width, height, x and y position are specified. The Nexus 5’s final bootloader image, as far as I can tell, only accesses this partition from aboot; SBL1 is not affected on this device. For the curious, I have a Python3 script which can extract these images at https://gist.github.com/shinyquagsire23/ba0f6209592d50fb8e4166620228aaa5.

A few examples of Nexus 5 imgdata resources

imgdata later became raw_resources, and at an undetermined point, the same RLE decompression and metadata interpreting was copied into SBL1 for use in boot paths where the battery has discharged significantly. If the battery is discharged too far, SBL1’s pm_sbl_chg_check_weak_battery_status will display LGE_PM_NO_CHARGER for boot attempts made without a charger connected, LGE_PM_WEAK_CHARGING_ON for boot attempts with a charger connected, and LGE_PM_NO_BATERY_ANI_* for boot attempts made without a battery. A script for extracting raw_resources can be found at https://gist.github.com/shinyquagsire23/b69ca343fd2f246aee882ecb5af702bd.

A few examples of Q710 resources

On normal boot paths, aboot reads raw_resources to display the boot logo, download mode graphic, and verified boot statuses for devices which allow unlocking. In my case, the Q710/Q720 does not allow for unlocking, so this boot path is never reached on these devices. However, the graphics still exist I guess on the off chance that they allowed it to happen.

For the C inclined, the format of raw_resources can be summarized in these structs: typedef struct boot_img_header { char magic[0x10]; uint32_t num_imgs; uint32_t version; char device[0x10]; uint32_t signature_offs; } boot_img_header;

typedef struct img_info { char name[0x28]; uint32_t data_offset; uint32_t data_size; uint32_t width; uint32_t height; uint32_t offs_x; uint32_t offs_y; } img_info;

The following calculation is performed in order to determine the output pointer to be used during decompression: bpp = 24 screen_stride = fbinfo->screen_width; fbuf_offset = offs_x + (screen_stride * offs_y); fbuf_out = (fbuf_offset * (bpp / 8)) + fbinfo->buffer;

offs_x and offs_y are not bounds checked, and fbinfo->buffer is known in SBL1 and aboot, allowing for a controlled arbitrary write in both environments.

SBL1 load_res_888rle_image Arbitrary Write

This boot path requires discharging the battery to below 0%. While this is less feasible for any practical usage, performing the arbitrary write at this point allows patching SBL1 to disable signature verification before TEE and aboot are loaded. Any of the LGE_PM_* images can be hijacked selectively for arbitrary code execution, though for my PoC I used LGE_PM_NO_CHARGER specifically because I didn't want to accidentally brick myself (or well, I didn't want to have to beep out eMMC wires on the board to unbrick).

A 32-bit x offset can be calculated for any given address divisible by 3 using the following calculation: offset_x = (((0x100000000 + target_addr) - 0x90000000) / 3) & 0xFFFFFFFF

Data written to this arbitrary address can be kept contiguous by specifying the image width to be the same as the screen width. The height should then be rounded up from the payload size to ensure all data is written properly. So really by the end, this isn't an arbitrary write so much as it is an arbitrary memcpy at Secure EL3.

aboot Arbitrary Write

The aboot arbitrary write functions identically to SBL1: Any image can be selected to perform the arbitrary write. Most notably, this includes any lglogo_image_* graphic, which is displayed by default on every boot. The framebuffer is generally fixed to address 0x90001000, which means that by using the arbitrary write to gain code execution, the original graphic which was used to obtain the arbitrary write can be written to the screen following hijacking to, in effect, make it appear as if boot flow has not been modified at all, for better or for worse.

A good question that might be raised after looking briefly at the structs earlier would be, "wait, there's a signature offset, why does any of this work if raw_resources contains a signature?" And yes, raw_resources contains a signature! But it's a useless signature because this signature is only checked in aboot while displaying verifiedboot_* images. At some point, XDA users found out that you could swap the LG boot logos over the verifiedboot_* images so that when they unlocked their devices they wouldn't have to see the AVB boot nag messages. Naturally, this defeats the point of Google's Verified Boot spec since it would potentially allow a bootloader be unlocked without the user knowing, so LG added a signature. But it’s only checked for the verified boot images.

As a minor note, unlike SBL1, aboot will also select between raw_resources_a and raw_resources_b depending on the A/B boot slot.

Practical Exploitation

I started by exploiting SBL1, partially because Secure EL3 is just cooler than nonsecure EL1, but also because the framebuffer address was more obviously seen than in aboot (though I later found the aboot framebuffer address anyhow). At this point in execution all of the hardware is initialized and no other bootloaders have been loaded, so we're basically free to patch sigchecks and control the entire phone!

As it turns out though, SBL1 takes a bit more work to actually exploit, because unlike aboot, its segments aren't set RWX. I'm not really sure why aboot has all of its segments RWX, like at that point it's more of a 'boot' than a 'secure boot' if they can't even bother to use the easiest security option available.

In any case, ROP is required briefly to bypass the MMU's NX bit. This isn't too terrible, since SBL1 actually has a routine we can jump to to disable the MMU, though it requires a bit of finnagling to get correct.

So in summary, the exploitation process goes as follows: - Flash raw_resources_a.img to eMMC (ie via kernel execution, LG LAF, soldered wires and a hardware flasher, etc). - For SBL1 hax, drain the battery to below 0%. For my Q710, I drained most of the battery by leaving the screen at max brightness with sleep disabled until the phone powered off on its own after several hours. To drain the remaining battery, I charged enough to enter LAF download mode and left it to drain with the screen on for 2-3 hours. - Hold Power and Volume Down until the phone restarts. If the phone discharged enough, the phone should restart into the payload. - The phone can be plugged in to boot into aboot and Android normally, but the payload will now execute every time the payload-injected graphic is displayed.

To exploit SBL1: - raw_resources_a is modified such that the x offset is set to 0x2801CF5C, the width to 1080, and the height to 5. This will decompress LGE_PM_NO_CHARGER (now containing the contents of payload.bin) to 0x08056E14, slightly higher than the stack pointer during decompression. - The image is decompressed and load_res_888rle_image exits. The previous LR has now been overwritten by a pointer to a Thumb-mode pop {pc} ROP slide, to account for possible offsetting error. - At the end of the ROP slide, the following ROP instruction sequence is executed:

pop {r4-r12, pc} ; r8 is now set to SBL1_ARM_MMU_DISABLE, and r12 is now set to SBL1_THUMB_BX_R8

pop {r4-r6, lr} ; LR is set to the payload pointer orr r12, r12, #0x1 bx r12 ; jump to SBL1_THUMB_BX_R8

bx r8 ; jump to SBL1_ARM_MMU_DISABLE with lr now set to our payload

youtube

Proof-of-Concept, and Future Plans

For those interested in experimenting, a PoC can be found here. Note that this is specifically for the LG Q710, and contains offset specific to the AMZ LG Stylo 4 (Q710ULM, 20c_00_AMZ_US_OP_1121). I'm planning on polishing things up further, however my current boot takeover involves two other vulnerabilities that I'd like to give a bit more time to make sure they're actually fixed/close to being fixed before releasing.

In the meantime I'd be interested in seeing if anyone else is interested in porting this to other LG devices, since I only own a Nexus 5, a Q710 and a Q720. As it is, these vulns will allow bootloader unlocking at a minimum on most older Qualcomm LG devices, and secure EL3 on newer ones, which should be very interesting for anyone interested in finding vulnerabilities in QSEE/similar on LG devices.

Singapore has taken the lead in Asia’s booming dance music industry with the launch of a new state of the art music production studio, TITAN Studios.

It takes a true leader to recognize a need find a solution and TITAN Studios is a perfect example, with the new venture formed between international star DJ and producer, DJ Adam Sky & Jupiter Labs. To them, TITAN Studios was born out of a necessity.

Sky has toured and performed all over Asia, and throughout his travel he began to notice that there was a gap in dance music production facilities within Asia. He noted that there were studios in and around Asia, but many were built around different ideologies and unable to offer the dynamic facility needs which many dance music producers need nowadays. Jupiter Labs saw the same thing, and together, they created the perfect solution: TITAN Studios.

TITAN Studios was built with the sole purpose to expand the horizons and creativity of every person that walked through the door. They’ve got it all, from vintage analog gear and setup to seamless interconnections with digital recoding and production capabilities. Planted right in the center of Singapore’s creative epicenter, Duxton Hill, TITAN is now home to one of the region’s few purpose built electronic dance music production studio facilities.

The pride and joy of the studio is the variety they offer through three different studio spaces, with the primary studio space priding itself on being analog to the core, offering a full suite of analog and digital production equipment. The other Studio rooms work as digital/MIDI hybrids, ideal for sessions when inspiration hits you and you need to put your ideas down.

The edge TITAN Studios carries is its versatility. Adam Sky & Jupiter Labs knew that in order to fill the gap in Singapore, they needed to create a studio that offered as much flexibility as possible to accommodate anyone’s creative approach. Whether you’re an Ableton user, Cubase, Studio One, Logic or Fruity Loops producer, TITAN offers digital interfacing via numerous digital audio interface options including Focusrite Sapphire Pro’s, MOTU AVB arrays, a plethora of Native Instruments gear and several flagship studio items from Presonus. TITAN Studios also provides over 25,000 instruments and digital samples for you to work with and keep the inspiration flowing.

The usual sort of components and units are available on site such as an extensive Midi keyboard and synth line up, Maschine and Maschine Studio units, but their outboard hardware list is ever evolving. If it doesn’t exist in their current line up but you would like to use it, all you have to do is let them know and they will source it for you through their partner network. They sky is truly the limit.

TITAN Studios is more than just a studio, they are invested in providing every opportunity to allow artists to create, which is evident through their ‘on tour’ support. They are available for last minute ‘on tour’ production, edits, mixdowns and mastering. They also have partnered with several boutique and leading hotel chains within walking distance of their studios in Singapore. Most importantly, they have a pantry full of energy drinks, snack food and coffee machines to keep you going all night!

TITAN Studios is the studio that lives up to every expectation. Whether you’re an artist, producer, mix engineer, DJ, performer, or just someone who wants to be immersed in a highly inspirational culture, TITAN Studios is the place to be.

The RME Fireface audio interface is a go-to for many professional live events and gigs, with many broadcasting and agencies specifying this particular model.

The interface has 12 analog I/Os.

12 Inputs – XLR inputs with Mic/Instrument preamps on the front and 8 balanced line inputs on the back

12 Outputs . 8 balanced line outputs on the back, and 2 hi-power line stereo phone outputs.

As the price-tag is particularly high, we advise giving some serious thought to whether or not you will need this caliber of interface. Only the alternative would be to purchase a less expensive interface, and put money into bettering sample libraries and connectivity equipment, which will have a tremendous impact on the overall sound quality of the live system.

If you’re interesting in learning more about this interface, take a look at the demonstration video below:

Universal Audio Apollo 8

The Universal Audio Apollo 8 interface does not have MIDI I/O functionality. However, it does have a certain use case.

UAD is a company which is known for making great software plugins which are modelled after iconic hardware and vintage gear. These particular plugins run on DSP chips, which is an acronym for Digital signal processing; These chips are embedded within the Apollo 8 interface, and therefore allows the interface to free up your computer’s processing power (particularly helpful if you are someone who wants to be able to use a lot of effects during a live performance.

The Apollo 8 has Thunderbolt connectivity, two main outputs alongside 8 line outputs. It also features a word clocks, ADAT and S/PDIF connectors.

16+ Outputs

MOTU 16A

The MOTU 16A (96kHz, 32Bit) is the world’s first Thunderbolt connectivity interface with 16 analog input & outputs, alongside 48-channel mixing and AVB networking

The MOTU 16A’s main advantage over other audio interfaces, especially in a live performance environment is that it keeps latency to an absolute minimum (a handful of samples at most). It achieves this through the Thunderbolt connectivity, which only has a 1.4ms round-trip latency time.

What is time-sensitive networking?

Time-sensitive networking (TSN) is the most recent leg of the journey that will make critical data available where and, most importantly, when it’s needed. The automotive industry’s use of audio video bridging has evolved into time-sensitive networking for in-vehicle and out-of-vehicle communications.

But what exactly is TSN, and why does it matter?

“On the one hand, time-sensitive networking denotes a set of IEEE 802 standards, which extends the functionality of Ethernet networks to support a deterministic and high-availability communication on Layer 2,” explains Dipl. Ing. André Hennecke, researcher at DFKI, a research center in Kaiserslautern, Germany. “In particular, this includes an improved timing synchronization and a real-time scheduling method, enhancements of the stream reservation protocol, explicit path control and network policing procedures.”

On the other hand, the term “time-sensitive network” is also used to designate a series of acts from different organizations to enable a deterministic communication via Ethernet, not only with a focus on Layer 2, but also with a view on Layer 3 (DetNet), applications and certification processes, such as those from AVnu Alliance, says Hennecke.

“It’s possible to have a network that offers no value to a customer, even though it conveys 100% of the requested information, simply because of the transmission latency it introduces,” warns Doug Taylor, principal engineer, Concept Systems, a system integrator in Albany, Oregon. The aim of TSN is to eliminate that latency for critical data by reserving a traffic lane for those packets.

“In the generic sense, TSN is a set of capabilities being added to standard Ethernet to support applications that need deterministic characteristics for data transfer.”

At one level, time sensitive networking it is a set of IEEE 802.1 and 802.3 standards, explains Paul Didier, solutions architect manager at Cisco. “The objective is to enhance Ethernet and core standard networking to better support time-sensitive applications, such as industrial automation control,” he says.

“We’re trying to match up standard networking with a lot of the requirements coming out of industrial automation and control. The concept of these control transactions or messages is a little challenging. Control engineers think they’ve got a controller or motor, and there’s a wire between the two of them. Technically, they understand that moving to standard networks and being able to do things in those models makes things a lot easier. Queuing the stuff up is counter-intuitive. They’re looking for deterministic network performance characteristics around latency, jitter and reliability that are easy to implement and use. It gives them an open and interconnected network that allows much more freely flowing information from those devices and to enhance and add to those devices over time, which drives the overall story of the IoT, where you can do off-line or close-to-the-machine. You need access to the data without having to drop extra lines in. It’s about convergence. There’s all of this IIoT, and it’s all about these things using the Internet. Aren’t there different requirements? Isn’t there a reason they haven’t used the Internet? Should we make some modifications?”

At the heart of TSN are mechanisms that provide time synchronization for networked devices and scheduled forwarding of defined traffic flows through the network, explains Markus Plankensteiner, vice president, sales industrial, North America, and global alliance manager, TTTech Computertechnik (www.tttech.com). “Through time synchronization and scheduling, TSN delivers deterministic communication over standard Ethernet, thereby enabling the convergence of critical control traffic with data traffic over one infrastructure without the need for gateways or proprietary solutions,” he says.

“The TSN standards define mechanisms for the time-sensitive transmission of data over Ethernet networks; these in particular address the transmission of data at very low latency and high availability, allowing for time-determination communication and synchronization,” says Sari Germanos, open automation business development manager, B&R Industrial Automation.

Time-sensitive networking is a collection of projects aimed at improving Ethernet, and specifically Internet technologies for time synchronization, explains Joey Stubbs, P.E., North American representative, EtherCAT Technology Group. “These projects are intended to improve routing, pre-emption, time synchronization, security and throughput of Ethernet traffic for A/V streaming and bridging,” he says. The IEEE 802.1 standard encompasses the work of the TSN Task Group, which used to be called the AVB Task Group for audio video bridging.

Fieldbuses are proprietary, well-designed for the applications they support, but getting data out of them is a bear, says Didier. “We can support that much better than the much-less-deterministic methods that we currently have,” he explains. “They have control problems they’re trying to solve. We’ve got an ecosystem we’re trying to build this into. This isn’t going to be a separate network configuration. It’s simply incorporated in the standard tools that you use. The idea is those programs understand the control loops and what information needs to come in and leave. The network will say it can handle it, sometimes with modifications, and push it out into the network. That’s the architecture we’re putting together on top of the IEEE standards.”

New Post has been published on http://engineer.city/emulation-platform-scales-up-to-15-billion-gates/

Emulation platform scales up to 15 billion gates

Mentor Graphics has launched the third generation of its emulation platform, increasing throughput by a factor of five and potentially emulating the largest system-on-chip designs with up to 15 billion gates.

The Veloce StratoM high-capacity emulator and Veloce Strato OS enterprise-level operating system combine to link multiple emulators to data centre processing.

The StratoM, which is currently on site at major customers, reaches 2.5 billion gates capacity when fully loaded with 64 Advanced Verification Boards (AVBs) and consumes up to 50KW (22.7 W/Mgate) of power. Multiple systems can be linked together using the Strato operating system to reach 15 bn gates.

Other performance improvements include: total throughput up to 5X (fastest compile-runtime-debug sequence), time to visibility up to 10X (fastest time to debug), compilation time up to 3X (with 100% success rate) and co-model bandwidth up to 3X (fastest virtual co-model solution available).

The enterprise-level operating system forms the foundation for a common infrastructure for all Veloce Strato hardware and software applications.

The OS is hardware-platform independent so that Veloce Apps and Protocol Solutions are interchangeable between hardware platforms, supporting the Veloce Power App, Veloce DFT (design or test) App and Protocol Solutions such as Veloce VirtuaLAB (virtual peripherals), iSolve for physical peripherals and soft models. The OS is modular to serve as a common front-end for a full range of solutions from verification through prototyping to validation.

“We are excited to announce the new Veloce Strato Platform, and equally delighted that Veloce StratoM is already in the hands of our largest customers,” said Eric Selosse, vice president and general manager of the Mentor Emulation Division. “Early feedback is very positive, and there is clear indication that the Veloce Strato platform defines a roadmap to 15BG that is needed for the emulation market for the next five years and beyond.”

Veloce is a core technology for Mentor’s Enterprise Verification Platform (EVP) that boosts productivity in ASIC and SoC functional verification by combining advanced verification technologies.

These include Questa verification and Visualizer debug tools alongside Veloce, creating a globally accessible, high-performance datacentre resource that supports project teams around the world.

Mentor is currently being acquired by Siemens to become part of the Product Lifecycle Management (PLM) software business of Siemens Digital Factory (DF) Division.
