AI risk analysis
- Summary
- The Metasploit Framework Web Service REST API has a critical authentication bypass vulnerability in its credential management endpoints, allowing unauthenticated attackers to read, modify, or delete all stored credentials including passwords, hashes, and private keys. This affects versions through 6.5.4 and is fixed in 6.5.5.
- Exploitability
- Exploitation is extremely easy with no prerequisites - any attacker who can reach the default 0.0.0.0:8080 listener can immediately access all credential records without authentication.
- Blast radius
- The impact is severe as attackers can access sensitive team credentials including passwords, hashes, and private keys for shared engagements, potentially leading to widespread compromise of systems and data access.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to Metasploit Framework 6.5.5 immediately to receive the fix that adds warden.authenticate! to both the update_credential and delete_credentials handlers.

NVD description
The Metasploit Framework Web Service REST API (msf-ws) exposes the credential store through Msf::WebServices::CredentialServlet. Every mutating and read route in this servlet calls warden.authenticate! before processing a request, except the update_credential (PUT) and delete_credentials (DELETE) handlers for /api/v1/credentials, which omit the authentication call entirely. Because these handlers call directly into lib/msf/core/db_manager/cred.rb, which performs no authorization check of its own, any client able to reach the web service on its default 0.0.0.0:8080 listener can read, modify, or permanently delete every stored credential record — including passwords, hashes, and private keys stored for a shared team engagement — without presenting any authentication. All published versions of Metasploit Framework through 6.5.4 are affected. The issue is fixed in 6.5.5 by adding warden.authenticate! as the first statement in both handlers, matching the pattern used by every other route in the API.
