Speedup Improvements of MSFVenom & New Modules

This week, we have added new modules to Metasploit Framework targeting Cisco Catalyst SD-WAN controllers and osTicket as well as updates and improvements to Windows service-for-user persistence, and LDAP/ADCS-related modules to automatically report related services resulting in an improved data stream, which can be queried by using the services command.

We also landed an improvement to msfvenom’s bootup time, thanks to bcoles, resulting in an approximate two-times speedup.

AD/CS Authenticated Web Enrollment Services Module

Authors: Spencer McIntyre, bwatters-r7, and jhicks-r7

Type: Auxiliary

Pull request: #20752 contributed by bwatters-r7

Path: admin/http/web_enrollment_cert

Description: This adds a new auxiliary/admin/http/web_enrollment_cert modules that allows certificates to be issued from an Active Directory Certificate Services Web Enrollment portal. Its usage is the same as the auxiliary/admin/http/icpr_cert module but enables operators to issue certificates when the web enrollment portal is accessible but the MS-ICPR service is not.

Pull request: #20948 contributed by ArkaprabhaChakraborty

Path: gather/osticket_arbitrary_file_read

AttackerKB reference: CVE-2026-22200

Windows Service for User (S4U) Scheduled Task Persistence - Event Trigger

Authors: Brandon McCann "zeknox" bmccann@accuvant.com, Thomas McCarthy "smilingraccoon" smilingraccoon@gmail.com, and h00die

Type: Exploit

Pull request: #20814 contributed by h00die

Path: windows/persistence/service_for_user/event

Description: Updates the Windows service-for-user persistence technique.

Enhancements and features (7)

• #20814 from h00die - Updates the Windows service-for-user persistence technique.

• #20973 from bitstr3m-48 - This release enables command execution for non-interactive HWBridge sessions via the sessions -c flag. Additionally, the hwbridge/connect module now preserves parsed JSON error bodies from failed HTTP responses, which improves error messaging.
• #20977 from g0tmi1k - This updates the exploit/unix/webapp/php_eval module to have a FORMDATA datastore option, which adds HTTP POST-request support and makes the HEADERS datastore option consistent with other modules.
• #20979 from g0tmi1k - This updates the exploit/unix/webapp/php_include module with additional datastore options and make its usage more consistent with the similar exploit/unix/webapp/php_eval module.
• #21031 from zeroSteiner - Enhances the Metasploit’s LDAP/ADCS-related modules to automatically report related services (LDAP, DCERPC/ICertPassage/ADCS CA) and to improve vulnerability reporting by associating findings with the affected LDAP object’s DN (and, for ADCS template findings, the template name) so results are uniquely keyed and easier to interpret.
• #21143 from SaiSakthidar - This bumps the Metasploit payloads to include changes that enable the PHP Meterpreter to open TCP server sockets. This enables operators to listen for inbound connections on compromised hosts and closes a feature gap between PHP and the other Meterpreters.
• #21229 from bcoles - This updates the msfvenom utility to use the metadata cache. The result is roughly 2x faster execution times when listing modules

Bugs fixed (1)

• #21153 from Nayeraneru - This fixes an issue with some mutable constant datastore options. Using shared options like CHOST or CPORT are not changing visibility across modules anymore.

Documentation added (1)

• #21221 from cgranleese-r7 - This PR improves module_doc_template.md with examples to better guide contributors.

Additional Adapters and More Modules

This week, we added a whole new bunch of HTTP/HTTPS-based CMD payloads for X64 and X86 versions of Windows. The additional breadth of selectable payloads and delivery techniques allows users new options to tailor the attack workflow for their environment. This was contributed by bwatters-r7. Adding new architectures for adapted payloads is surprisingly easy and something a first-time contributor might want to look into!

New modules added to Metasploit Framework also allow for targeting FreeScout and Grav CMS, both of which result in remote code execution. These modules were contributed by Chocapikk and x1o3 respectively. Thanks!

Thanks to g0tmi1k, Metasploit Framework now also includes an exploit module, multi/http/os_cmd_exec, which allows for targeting generic HTTP command execution vulnerabilities where user-supplied input is directly passed to system execution functions via an HTTP request. This can result in a Meterpreter shell on the remote target.

To round this week off, we have a new persistence technique on Windows, thanks to Nayeraneru, which abuses the HKCU\Environment\UserInitMprLogonScript registry value to execute a payload at user logon.
