Nmap Defcon Release! 80+ improvements include new NSE scripts/libs, new Npcap, etc.

Fellow hackers, I'm here in Las Vegas for Defcon and delighted to release Nmap 7.80.  It's the first formal Nmap release in more than a year, and I hope you find it worth the wait! The main reason for the delay is that we've been working so hard on our Npcap Windows packet capturing driver.  As many of you know, Windows Nmap traditionally depended on Winpcap for packet capture.  That is great software, but it has been discontinued and has seen no updates since 2013. It doesn't always work on Windows 10, and it depends on long-deprecated Windows API's that Microsoft could remove at any time.  So we've spent the last few years building our own Npcap raw packet capturing/sending driver, starting with Winpcap as the base.  It uses modern APIs and is more performant as well as more secure and more featureful.  We've had 15 Npcap releases since Nmap 7.70 and we're really happy with where it is now.  Even Wireshark switched to Npcap recently.  More details on Npcap can be found at https://npcap.org. But Windows users aren't the only ones benefiting from this new Nmap release.  It includes 80+ cross-platform improvements you can read about below, including 11 new NSE scripts, a bunch of new libraries, bug fixes and performance improvements. map 7.80 source code and binary packages for Linux, Windows, and Mac are available for free download from the usual spot: https://nmap.org/download.html If you find any bugs in this release, please let us know on the Nmap Dev list or bug tracker as described at https://nmap.org/book/man-bugs.html. Here is the full list of significant changes since 7.70: map 7.70 source code and binary packages for Linux, Windows, and Mac are available for free download from the usual spot: https://nmap.org/download.html If you find any bugs in this release, please let us know on the Nmap Dev list or bug tracker as described at https://nmap.org/book/man-bugs.html. Here is the full list of significant changes: o [Windows] The Npcap Windows packet capturing library (https://npcap.org/)  is faster and more stable than ever. Nmap 7.80 updates the bundled Npcap  from version 0.99-r2 to 0.9982, including all of these changes from the  last 15 Npcap releases: https://nmap.org/npcap/changelog o [NSE] Added 11 NSE scripts, from 8 authors, bringing the total up to 598!  They are all listed at https://nmap.org/nsedoc/, and the summaries are  below:  + [GH#1232] broadcast-hid-discoveryd discovers HID devices on a LAN by    sending a discoveryd network broadcast probe. [Brendan Coles]  + [GH#1236] broadcast-jenkins-discover discovers Jenkins servers on a LAN    by sending a discovery broadcast probe. [Brendan Coles]  + [GH#1016][GH#1082] http-hp-ilo-info extracts information from HP    Integrated Lights-Out (iLO) servers. [rajeevrmenon97]  + [GH#1243] http-sap-netweaver-leak detects SAP Netweaver Portal with the    Knowledge Management Unit enabled with anonymous access. [ArphanetX]  + https-redirect detects HTTP servers that redirect to the same port, but    with HTTPS. Some nginx servers do this, which made ssl-* scripts not run    properly. [Daniel Miller]  + [GH#1504] lu-enum enumerates Logical Units (LU) of TN3270E servers.    [Soldier of Fortran]  + [GH#1633] rdp-ntlm-info extracts Windows domain information from RDP    services. [Tom Sellers]  + smb-vuln-webexec checks whether the WebExService is installed and allows    code execution. [Ron Bowes]  + smb-webexec-exploit exploits the WebExService to run arbitrary commands    with SYSTEM privileges. [Ron Bowes]  + [GH#1457] ubiquiti-discovery extracts information from the Ubiquiti    Discovery service and assists version detection. [Tom Sellers]  + [GH#1126] vulners queries the Vulners CVE database API using CPE    information from Nmap's service and application version detection.    [GMedian, Daniel Miller] o [GH#1291][GH#34][GH#1339] Use pcap_create instead of pcap_live_open in  Nmap, and set immediate mode on the pcap descriptor. This solves packet  loss problems on Linux and may improve performance on other platforms.  [Daniel Cater, Mike Pontillo, Daniel Miller] o [NSE] Collected utility functions for string processing into a new  library, stringaux.lua. [Daniel Miller] o [NSE] New rand.lua library uses the best sources of random available on  the system to generate random strings. [Daniel Miller] o [NSE] New library, oops.lua, makes reporting errors easy, with plenty of  debugging detail when needed, and no clutter when not. [Daniel Miller] o [NSE] Collected utility functions for manipulating and searching tables  into a new library, tableaux.lua. [Daniel Miller] o [NSE] New knx.lua library holds common functions and definitions for  communicating with KNX/Konnex devices. [Daniel Miller] o [NSE][GH#1571] The HTTP library now provides transparent support for gzip-  encoded response body. (See https://github.com/nmap/nmap/pull/1571 for an  overview.) [nnposter] o [Nsock][Ncat][GH#1075] Add AF_VSOCK (Linux VM sockets) functionality to  Nsock and Ncat. VM sockets are used for communication between virtual  machines and the hypervisor. [Stefan Hajnoczi] o [Security][Windows] Address CVE-2019-1552 in OpenSSL by building with the  prefix "C:\Program Files (x86)\Nmap\OpenSSL". This should prevent  unauthorized users from modifying OpenSSL defaults by writing  configuration to this directory. o [Security][GH#1147][GH#1108] Reduced LibPCRE resource limits so that  version detection can't use as much of the stack. Previously Nmap could  crash when run on low-memory systems against target services which are  intentionally or accidentally difficult to match. Someone assigned  CVE-2018-15173 for this issue. [Daniel Miller] o [GH#1361] Deprecate and disable the -PR (ARP ping) host discovery  option. ARP ping is already used whenever possible, and the -PR option  would not force it to be used in any other case. [Daniel Miller] o [NSE] bin.lua is officially deprecated. Lua 5.3, added 2 years ago in Nmap  7.25BETA2, has native support for binary data packing via string.pack and  string.unpack. All existing scripts and libraries have been updated.  [Daniel Miller] o [NSE] Completely removed the bit.lua NSE library. All of its functions are  replaced by native Lua bitwise operations, except for `arshift`  (arithmetic shift) which has been moved to the bits.lua library. [Daniel  Miller] o [NSE][GH#1571] The HTTP library is now enforcing a size limit on the  received response body. The default limit can be adjusted with a script  argument, which applies to all scripts, and can be overridden case-by-case  with an HTTP request option. (See https://github.com/nmap/nmap/pull/1571  for details.)  [nnposter] o [NSE][GH#1648] CR characters are no longer treated as illegal in script  XML output. [nnposter] o [GH#1659] Allow resuming nmap scan with lengthy command line [Clément  Notin] o [NSE][GH#1614] Add TLS support to rdp-enum-encryption. Enables determining  protocol version against servers that require TLS and lays ground work for  some NLA/CredSSP information collection. [Tom Sellers] o [NSE][GH#1611] Address two protocol parsing issues in rdp-enum-encryption  and the RDP nse library which broke scanning of Windows XP. Clarify  protocol types [Tom Sellers] o [NSE][GH#1608] Script http-fileupload-exploiter failed to locate its  resource file unless executed from a specific working  directory. [nnposter] o [NSE][GH#1467] Avoid clobbering the "severity" and "ignore_404" values of  fingerprints in http-enum. None of the standard fingerprints uses these  fields. [Kostas Milonas] o [NSE][GH#1077] Fix a crash caused by a double-free of libssh2 session data  when running SSH NSE scripts against non-SSH services. [Seth Randall] o [NSE][GH#1565] Updates the execution rule of the mongodb scripts to be  able to run on alternate ports. [Paulino Calderon] o [Ncat][GH#1560] Allow Ncat to connect to servers on port 0, provided that  the socket implementation allows this. [Daniel Miller] o Update the included libpcap to 1.9.0. [Daniel Miller] o [NSE][GH#1544] Fix a logic error that resulted in scripts not honoring the  smbdomain script-arg when the target provided a domain in the NTLM  challenge.  [Daniel Miller] o [Nsock][GH#1543] Avoid a crash (Protocol not supported) caused by trying  to reconnect with SSLv2 when an error occurs during DTLS connect. [Daniel  Miller] o [NSE][GH#1534] Removed OSVDB references from scripts and replaced them  with BID references where possible. [nnposter] o [NSE][GH#1504] Updates TN3270.lua and adds argument to disable TN3270E  [Soldier of Fortran] o [GH#1504] RMI parser could crash when encountering invalid input [Clément  Notin] o [GH#863] Avoid reporting negative latencies due to matching an ARP or ND  response to a probe sent after it was recieved. [Daniel Miller] o [Ncat][GH#1441] To avoid confusion and to support non-default proxy ports,  option --proxy now requires a literal IPv6 address to be specified using  square-bracket notation, such as --proxy [2001:db8::123]:456. [nnposter] o [Ncat][GH#1214][GH#1230][GH#1439] New ncat option provides control over  whether proxy destinations are resolved by the remote proxy server or  locally, by Ncat itself. See option --proxy-dns. [nnposter] o [NSE][GH#1478] Updated script ftp-syst to prevent potential endless  looping.  [nnposter] o [GH#1454] New service probes and match lines for v1 and v2 of the Ubiquiti  Discovery protocol. Devices often leave the related service open and it  exposes significant amounts of information as well as the risk of being  used as part of a DDoS. New nmap-payload entry for v1 of the  protocol. [Tom Sellers] o [NSE] Removed hostmap-ip2hosts.nse as the API has been broken for a while  and the service was completely shutdown on Feb 17th, 2019. [Paulino  Calderon] o [NSE][GH#1318] Adds TN3270E support and additional improvements to  tn3270.lua and updates tn3270-screen.nse to display the new  setting. [mainframed] o [NSE][GH#1346] Updates product codes and adds a check for response length  in enip-info.nse. The script now uses string.unpack. [NothinRandom] o [Ncat][GH#1310][GH#1409] Temporary RSA keys are now 2048-bit to resolve a  compatibility issue with OpenSSL library configured with security level 2,  as seen on current Debian or Kali.  [Adrian Vollmer, nnposter] o [NSE][GH#1227] Fix a crash (double-free) when using SSH scripts against  non-SSH services. [Daniel Miller] o [Zenmap] Fix a crash when Nmap executable cannot be found and the system  PATH contains non-UTF-8 bytes, such as on Windows. [Daniel Miller] o [Zenmap] Fix a crash in results search when using the dir: operator:    AttributeError: 'SearchDB' object has no attribute 'match_dir' [Daniel    Miller] o [Ncat][GH#1372] Fixed an issue with Ncat -e on Windows that caused early  termination of connections. [Alberto Garcia Illera] o [NSE][GH#1359] Fix a false-positive in http-phpmyadmin-dir-traversal when  the server responds with 200 status to a POST request to any  URI. [Francesco Soncina] o [NSE] New vulnerability state in vulns.lua, UNKNOWN, is used to indicate  that testing could not rule out vulnerability. [Daniel Miller] o [GH#1355] When searching for Lua header files, actually use them where  they are found instead of forcing /usr/include. [Fabrice Fontaine, Daniel  Miller] o [NSE][GH#1331] Script traceroute-geolocation no longer crashes when  www.GeoPlugin.net returns null coordinates [Michal Kubenka, nnposter] o Limit verbose -v and debugging -d levels to a maximum of 10. Nmap does not  use higher levels internally. [Daniel Miller] o [NSE] tls.lua when creating a client_hello message will now only use a  SSLv3 record layer if the protocol version is SSLv3. Some TLS  implementations will not handshake with a client offering less than  TLSv1.0. Scripts will have to manually fall back to SSLv3 to talk to  SSLv3-only servers. [Daniel Miller] o [NSE][GH#1322] Fix a few false-positive conditions in  ssl-ccs-injection. TLS implementations that responded with fatal alerts  other than "unexpected message" had been falsely marked as  vulnerable. [Daniel Miller] o Emergency fix to Nmap's birthday announcement so Nmap wishes itself a  "Happy 21st Birthday" rather than "Happy 21th" in verbose mode (-v) on  September 1, 2018. [Daniel Miller] o [GH#1150] Start host timeout clocks when the first probe is sent to a  host, not when the hostgroup is started. Sometimes a host doesn't get  probes until late in the hostgroup, increasing the chance it will time  out. [jsiembida] o [NSE] Support for edns-client-subnet (ECS) in dns.lua has been improved by:  - [GH#1271] Using ECS code compliant with RFC 7871 [John Bond]  - Properly trimming ECS address, as mandated by RFC 7871 [nnposter]  - Fixing a bug that prevented using the same ECS option table more than    once [nnposter] o [Ncat][GH#1267] Fixed communication with commands launched with -e or -c  on Windows, especially when --ssl is used. [Daniel Miller] o [NSE] Script http-default-accounts can now select more than one  fingerprint category. It now also possible to select fingerprints by name  to support very specific scanning. [nnposter] o [NSE] Script http-default-accounts was not able to run against more than  one target host/port. [nnposter] o [NSE][GH#1251] New script-arg `http.host` allows users to force a  particular value for the Host header in all HTTP requests. o [NSE][GH#1258] Use smtp.domain script arg or target's domain name instead  of "example.com" in EHLO command used for STARTTLS. [gwire] o [NSE][GH#1233] Fix brute.lua's BruteSocket wrapper, which was crashing  Nmap with an assertion failure due to socket mixup [Daniel Miller]: nmap:  nse_nsock.cc:672: int receive_buf(lua_State*, int, lua_KContext):  Assertion `lua_gettop(L) == 7' failed. o [NSE][GH#1254] Handle an error condition in smb-vuln-ms17-010 caused by  IPS closing the connection. [Clément Notin] o [Ncat][GH#1237] Fixed literal IPv6 URL format for connecting through HTTP  proxies. [Phil Dibowitz] o [NSE][GH#1212] Updates vendors from ODVA list for enip-info. [NothinRandom] o [NSE][GH#1191] Add two common error strings that improve MySQL detection  by the script http-sql-injection. [Robert Taylor, Paulino Calderon] o [NSE][GH#1220] Fix bug in http-vuln-cve2006-3392 that prevented the script  to generate the vulnerability report correctly. [rewardone] o [NSE][GH#1218] Fix bug related to screen rendering in NSE library  tn3270. This patch also improves the brute force script  tso-brute. [mainframed] o [NSE][GH#1209] Fix SIP, SASL, and HTTP Digest authentication when the  algorithm contains lowercase characters. [Jeswin Mathai] o [GH#1204] Nmap could be fooled into ignoring TCP response packets if they  used an unknown TCP Option, which would misalign the validation, causing  it to fail. [Clément Notin, Daniel Miller] o [NSE]The HTTP response parser now tolerates status lines without a reason  phrase, which improves compatibility with some HTTP servers. [nnposter] o [NSE][GH#1169][GH#1170][GH#1171]][GH#1198] Parser for HTTP Set-Cookie header  is now more compliant with RFC 6265:  - empty attributes are tolerated  - double quotes in cookie and/or attribute values are treated literally  - attributes with empty values and value-less attributes are parsed equally  - attributes named "name" or "value" are ignored  [nnposter] o [NSE][GH#1158] Fix parsing http-grep.match script-arg. [Hans van den  Bogert] o [Zenmap][GH#1177] Avoid a crash when recent_scans.txt cannot be written  to.  [Daniel Miller] o Fixed --resume when the path to Nmap contains spaces. Reported on Windows  by Adriel Desautels. [Daniel Miller] o New service probe and match lines for adb, the Android Debug Bridge, which  allows remote code execution and is left enabled by default on many  devices. [Daniel Miller] Enjoy this new release and please do let us know if you find any problems! Download link: https://nmap.org/download.html Cheers, Fyodor
