Unauthenticated super-admin escalation via group parameter
Published Dec 10, 2025 · Updated Dec 10, 2025
Authorization bypass in UBICOD Medivision Digital Signage 1.5.1 allows remote attackers to gain super-admin rights via an HTTP request. The /html/user endpoint accepts an ft[grp] GET parameter value of 3 and assigns super-admin privileges without performing an authorization check. No authentication or user interaction is required, and successful exploitation grants administrative control of the signage application.
