Unauthenticated access via SSO token path traversal
Published May 1, 2025 · Updated May 2, 2025
Authentication bypass in KUNBUS Revolution Pi PiCtory 2.5.0 through 2.11.1 allows remote attackers to gain authenticated access. The php/sso_login.php handler blindly appends the sso_token query value to its token directory and accepts any reachable existing path before creating a PHP session. No credentials or user interaction are required; the resulting access permits control of the device's I/O terminals and expansion modules.
