How CVE-2025-6485 Works
The vulnerability exists in the `/boafrm/formWlSiteSurvey` endpoint of TOTOLINK A3002R firmware version 1.1.1-B20200824.0128. The `formWlSiteSurvey` function improperly sanitizes user-supplied input passed through the `wlanif` parameter, allowing attackers to inject arbitrary OS commands. When malicious input is processed, the router executes these commands with root privileges due to insufficient input validation. The attack can be performed remotely without authentication, enabling complete device compromise. The vulnerability stems from directly concatenating user-controlled data into system commands without proper escaping or sanitization.
