## Technical details

A stack-based buffer overflow vulnerability (CWE-121) exists in the Tenda W12 router, specifically within the 'set_local_time_0' function of the '/bin/httpd' binary. The flaw is triggered by improper validation of the 'Time' argument, allowing an attacker to overwrite memory on the stack. This attack can be launched remotely over the network, though it requires low-level authentication (PR:L). Successful exploitation can lead to remote code execution (RCE) or a crash of the HTTP service (DoS). A public exploit is reportedly available.
