Unauthenticated router access via forged admin cookie

Published Oct 12, 2022 · Updated Apr 14, 2025

Improper authentication in Mediabridge Medialink V3.0 allows remote attackers to access the router interface via a crafted cookie. The /index.asp login handler accepts the forged Cookie value language=en; admin:language=en as an authenticated session without validating credentials. No credentials or user interaction are required; the public artifact demonstrates unauthorized interface access but does not document the exact data or actions exposed.
