CVE-2023-41966Network attack vector

Authenticated privilege escalation via unsafe parameter update

Published Oct 26, 2023 · Updated Jan 16, 2025

Privilege escalation in Sielco Radio Link and Analog FM transmitter firmware allows remote authenticated users to gain write privileges. The web application accepts an HTTP POST that changes an unspecified privileged parameter without enforcing the read-only account's authorization. Valid read-level credentials are required, and successful exploitation grants unauthorized write privileges; the affected parameter remains undisclosed.
