What is CVE-2025-57296?
CVE-2025-57296 is a medium-severity command injection vulnerability in Tenda Ac6 Firmware, published on 19 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Tenda AC6 router firmware 15.03.05.19 contains a command injection vulnerability in the formSetIptv function, which processes requests to the /goform/SetIPTVCfg web interface. When handling the list and vlanId parameters, the sub_ADBC0 helper function concatenates these user-supplied values into nvram set system commands using doSystemCmd, without validating or sanitizing special characters (e.g., ;, ", #). An unauthenticated or authenticated attacker can exploit this by submitting a crafted POST request, leading to arbitrary system command execution on the affected device.
