CVE-2022-25079Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized query string

Published Feb 22, 2022 · Updated Aug 3, 2024

OS command injection in TOTOLINK A810R firmware 4.1.2cu.5182_B20201026 allows remote attackers to execute commands via QUERY_STRING. The Main function passes attacker-controlled QUERY_STRING content to an operating-system command without neutralizing shell metacharacters. No authentication or user interaction is required, and successful exploitation grants control of the router through arbitrary command execution.
