Vulnerability from github – Published: 2026-05-15 03:30 – Updated: 2026-05-18 03:31

Details

Rapid7 Metasploit Pro is vulnerable to a local privilege escalation attack that allows users to gain SYSTEM level control of a Windows host. Upon startup the metasploitPostgreSQL service the subsequent postgres.exe service attempts to load an OpenSSL configuration file from a non-existent directory that is writable by standard users. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits an unprivileged user to bypass security controls and achieve a full host compromise under the agent's SYSTEM level access.

Severity

8.5 (High)

CVE-2026-7373 (GCVE-0-2026-7373)

Vulnerability from cvelistv5 – Published: 2026-05-15 02:06 – Updated: 2026-05-19 22:43

Title

Metasploit Pro on Windows: Local Privilege Escalation via OpenSSL Configuration File Loading

Summary

Rapid7 Metasploit Pro is vulnerable to a local privilege escalation attack that allows a user to gain SYSTEM level control of a Windows host. When started the metasploitPostgreSQL service would start the postgres.exe child process which would in turn load an OpenSSL configuration file from a static location. This static location would be writable by a pre-existing "vagrant" user, if they already existed on the system. Metasploit does not create local accounts, an Administrator would need to create it. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits the unprivileged vagrant user to bypass security controls and achieve a full host compromise under the agent's SYSTEM level access.

Severity

8.5 (High)
