Summary

A heap-based buffer overflow has been detected in the web server component of Tenda routers, specifically in their handling of the 'mac' parameter in POST requests. This flaw allows attackers to exploit the strcpy function, which directly uses user-supplied values without proper sanitization, leading to potential information leakage or unauthorized control over the program's execution flow. Users of the affected Tenda devices should take immediate action to secure their systems against possible exploitation.
