Name of the Vulnerable Software and Affected Versions Tenda AC6V2.0 version 15.03.06.23 multi

Description An issue exists in the /goform/WifiWpsStart component of the software. The index and mode parameters are controllable. When specific conditions are met during the sprintf function call, these parameters are concatenated into a temporary buffer (tmp) without any size validation. This lack of size checking results in a stack overflow condition.

Recommendations Update to a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the /goform/WifiWpsStart endpoint to minimize the risk of exploitation.
