Weekly Metasploit Update: NTLM Relay Priv Esc, MCP Server Integration, Paperclip AI RCE Chain, and more

This week’s release includes five new modules, including a full unauthenticated RCE chain for Paperclip AI and a VS Code extension persistence technique. On the post-exploitation side, the new windows/local/ntlm_relay_2_self module coerces the local machine account to authenticate via OpenEncryptedFileRaw (WebDAV), relays that NTLM authentication to a Domain Controller’s LDAP service, then uses the resulting LDAP session to write Shadow Credentials and obtain a Kerberos service ticket as Administrator via S4U2Proxy, enabling PsExec back to itself for SYSTEM access.On the enhancement side, the new MCP server plugin lets AI tools assist operators directly within a running msfconsole instance, and module check codes now return richer detail for users.New module content (5)Paperclip AI RCE using a chain of six API calls (CVE-2026-41679)Authors: Sagilayani https://github.com/sagilayani and h00die-gr3y h00die.gr3y@gmail.comType: ExploitPull request: #21547 contributed by h00die-gr3yPath: linux/http/paperclipai_unauth_rce_cve_2026_41679AttackerKB reference: CVE-2026-41679Description: Adds an exploit module for CVE-2026-41679 which exploits Paperclip.
