Guest-to-Administrator escalation via trusted role cookie
Published Apr 18, 2024 · Updated Aug 8, 2024
Privilege escalation in Electrolink FM, DAB, and TV transmitters allows remote authenticated users to gain Administrator access. The management interface accepts an attacker-modified Login cookie that replaces the GUEST role with ADMIN without validating its integrity. A guest session is sufficient; Administrator access exposes transmitter management operations with confidentiality, integrity, and availability impact.
