New ESC4 Templates for AD CS

Metasploit added capabilities for exploiting the ESC family of flaws in AD CS in Metasploit 6.3. The ESC4 technique in particular has been supported for some time now thanks to the ad_cs_cert_templates module which enables users to read and write certificate template objects. This facilitates the exploitation of ESC4 which is a misconfiguration in the access controls of the LDAP object, allowing an attacker to tamper with them. This is typically used by an attacker to modify a certificate template object they are capable of modifying to make it susceptible to ESC1. Metasploit offers a premade template for ESC1 that a user could select to perform this attack.

This attack workflow was expanded on this week with two new templates for ESC2 and ESC3. These new templates allow Metasploit users that are concerned about ESC1 being detected with alternative options for exploitation. Additionally, the premade templates can be edited, to for example restrict permissions to a particular SID by changing the SDDL text of the ntSecurityDescriptor.

WatchGuard XTM Firebox Unauthenticated Remote Command Execution

Authors: Charles Fol (Ambionics Security), Dylan Pindur (AssetNote), Misterxid, and h00die-gr3y h00die.gr3y@gmail.com
Type: Exploit
Pull request: #18915 contributed by h00die-gr3y
Path: linux/http/watchguard_firebox_unauth_rce_cve_2022_26318
AttackerKB reference: CVE-2022-26318

Description: This PR adds a module for a buffer overflow at the administration interface of WatchGuard Firebox and XTM appliances. The appliances are built from a cherrypy python backend sending XML-RPC requests to a C binary called wgagent using pre-authentication endpoint /agent/login. This vulnerability impacts Fireware OS before 12.7.2_U2, 12.x before 12.1.3_U8, and 12.2.x through 12.5.x before 12.5.9_U2. Successful exploitation results in remote code execution as user nobody.

Jenkins CLI Ampersand Replacement Arbitrary File Read

Authors: Vozec, Yaniv Nizry, binganao, h00die, and h4x0r-dz
Type: Auxiliary
Pull request: #18764 contributed by h00die
Path: gather/jenkins_cli_ampersand_arbitrary_file_read
AttackerKB reference: CVE-2024-23897

Description: This PR adds a new module to exploit CVE-2024-23897, an unauthorized arbitrary (first 2 lines) file read on Jenkins versions prior to 2.442 or for the LTS stream, versions prior to 2.426.3.

Enhancements and features (4)

  • #18906 from zeroSteiner - This PR adds support for leveraging the ESC4 attack on misconfigured AD-CS servers to introduce ESC2 and ESC3.
  • #18933 from sjanusz-r7 - Updates the new SQL session types to correctly remember previous commands that the user has entered.
  • #19003 from ArchiMoebius - Updates msfvenom and payload generation to support formatting payloads as a Zig buffer.
  • #19014 from cgranleese-r7 - Adds an initial set of acceptance tests for MySQL modules and session types.

Bugs fixed (3)

  • #18935 from zeroSteiner - This PR fixes a common user mistake when authenticating with LDAP modules. Now, users can specify either the USERNAME (user) and DOMAIN (domain.local) datastore options or the original format of just the USERNAME in the UPN format (user@domain.local). This fix updates the LDAP library.
  • #19007 from dwelch-r7 - Fixes a regression that affected exploit/multi/http/log4shell_header_injection module which stopped the module from running successfully.
  • #19021 from cgranleese-r7 - Updates the admin/mysql/mysql_enum module to work with newer versions of MySQL.
