CVE-2020-24034 describes an insecure deserialization vulnerability in Sagemcom F@ST 5280 routers running firmware version 1.150.61. An authenticated attacker can exploit this to achieve privilege escalation by altering the user value within a serialized session cookie, effectively assuming the role of the "internal" account. This allows for complete compromise, including flashing custom firmware, and is rated as High severity (CVSS 8.8). While no public exploit code or active exploitation has been observed, and community discussion is minimal, the potential impact is significant.
