Metasploit Wrap Up: This One Goes to Sixteen!

This One Goes to Sixteen!

Another banger from Metasploit with sixteen new modules, including ten exploit modules, with five on the CISA KEV list. Cisco, Papercut, Sonicwall, Jetbrains, and Langflow all have exploit modules, and not to be outdone, we even have a Metasploit scanner to watch the watchers!

ESC8 Relay: SMB to HTTP(S) via Kerberos

Author: Pushpender Rathore

Type: Auxiliary

Pull request: #21709 contributed by Pushpenderrathore

Path: server/relay/esc8_kerberos

CVE reference: CVE-2026-20929

Description: This introduces native Kerberos authentication relay capabilities to the framework’s relay stack. It includes a new auxiliary module (esc8_kerberos) that exploits CVE-2026-20929 by targeting AD CS Web Enrollment (ESC8). The module captures an SMB2 AP-REQ from a coerced client and seamlessly replays the authentication to the target certificate server over HTTP. This chain ultimately allows an attacker to issue a certificate for the coerced victim and obtain a valid Kerberos TGT without requiring their credentials.

Linux x64 Sandbox Environment Gate

Author: Massimo Bertocchi

Type: Evasion

Pull request: #21642 contributed by litemars

Path: linux/x64/sandbox_gate

Description: Adds a Linux x64 sandbox‑evasion module that performs lightweight runtime environment checks and aborts execution when a likely sandbox or VM is detected.

Authors: Adam Babis, William Perry, and sfewer-r7

Type: Exploit

Pull request: #21883 contributed by sfewer-r7

Path: linux/http/sonicwall_sma1000_couchdb_rce

CVE reference: CVE-2026-83549

Description: This adds an exploit module for the recent SonicWall SMA1000 zero-day exploit chain that was disclosed in the first week of September as being exploited in-the-wild. CVE-2026-83548 is an SSRF used to bypass auth. SMA1000-9427 is an RCE with low privileges via CouchDB read/write primitives. CVE-2026-83549 is a command injection in cmsSnmpTrap.sh for RCE with root privs. The patched version 12.5.0-02952 has been verified to successfully remediate this exploit chain.

JetBrains TeamCity Agent Polling Unauthenticated Remote Code Execution

Authors: Antoni Tremblay and sfewer-r7

Type: Exploit

Pull request: #21775 contributed by sfewer-r7

Path: multi/http/jetbrains_teamcity_rce_cve_2026_63077

CVE reference: CVE-2026-63077

Description: This introduces a new unauthenticated Remote Code Execution (RCE) exploit module for JetBrains TeamCity, targeting the vulnerability tracked as CVE-2026-63077. The module exploits an unsafe XStream deserialization flaw within the agent polling protocol to deliver and execute a one-shot JSP payload on the server. The module supports both Windows and Linux targets and features built-in cleanup logic to automatically unregister and remove the fake build agent created during the exploitation process.

Langflow AI authenticated RCE

Author: Richard Howe

Type: Exploit

Pull request: #21837 contributed by rmhowe425

Path: multi/http/langflow_auth_rce_cve_2026_19295

MCPJam Inspector Connect API Command Execution

Authors: Louay-075 and earthenvessel

Type: Exploit

Pull request: #21655 contributed by earthenvessel

Path: multi/http/mcpjam_inspector_rce

CVE reference: CVE-2026-23744

Description: This adds a new exploit module for CVE-2026-23744, an unauthenticated command execution vulnerability in MCPJam Inspector. The module targets the /api/mcp/connect endpoint. Vulnerable versions accept a JSON serverConfig object containing a command and args array, then use those values to start an MCP server. When MCPJam Inspector is exposed on a routable interface, an unauthenticated remote attacker can abuse this behavior to execute operating system commands as the user running MCPJam Inspector.

Bugs fixed (4)

• #21719 from Pushpenderrathore – Fixes a race condition in the module Metadata cache.
• #21838 from jheysel-r7 – Fixes payload choosing behaviour when swapping targets to auto-select the most fitting payload which can now also include Java payloads.
• #21853 from Pushpenderrathore – Three fixes to the core Rex::Proto::DNS forward/cache path that surface once the DNS server is used as a selective poisoner in front of a real upstream resolver
• #21861 from prithvee07 – Fixes a recent regression in the vsftpd_234_backdoor module where by updating the module to support ARCH_CMD payloads we inadvertently dropped support for cmd/unix/interact payloads. Both payloads are now supported.
