Detailsinfo

A vulnerability, which was classified as critical, has been found in Rapid7 Metasploit Pro 5.0.0. Affected by this issue is some unknown functionality of the file postgres.exe of the component metasploitPostgreSQL Service. The manipulation with an unknown input leads to a inclusion of functionality from untrusted control sphere vulnerability. Using CWE to declare the problem leads to CWE-829. The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was disclosed by Andrea Intilangelo. The advisory is available at docs.rapid7.com. This vulnerability is handled as CVE-2026-7373 since 04/29/2026. The exploitation is known to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/21/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
