Summary
A vulnerability was detected in Tenda AC18 version 15.03.05.05. Manipulation of the scanList argument in the sprintf function of /goform/SetDlnaCfg within the HTTP Request Handler component results in a stack-based buffer overflow. The attack can be executed remotely and the exploit is now public.
Risk Assessment
A remote attacker could exploit the buffer overflow to crash the device or potentially execute arbitrary code. This may result in disruption of network services or full compromise of the router.
Recommendation
Install the vendor's firmware update as soon as it becomes available and restrict access to the administrative interface from external networks. Until a patch is released, consider disabling or blocking the vulnerable endpoint.
