## Technical details

A denial of service (DoS) vulnerability exists in the Tenda W12 router, specifically within the 'cgiSysWebTimeoutSet' function of the '/bin/httpd' binary. The vulnerability is triggered by manipulating the 'web_over_time' argument within the Web Management Interface. An attacker with low-level privileges can exploit this over the network to cause an improper resource shutdown or release (CWE-404), leading to a denial of service. Public exploit code is reportedly available.
