Unauthenticated command execution via deviceName shell injection
Published Mar 26, 2024 · Updated Aug 6, 2024
Command injection in Tenda AC18 firmware 15.03.05.05 allows remote attackers to execute arbitrary commands through deviceName. The formsetUsbUnload handler passes the user-controlled deviceName value directly to doSystemCmd without neutralizing shell metacharacters. No authentication or user interaction is required, and injected commands execute on the router.
