Tenda FH1202 Stack-Based Buffer Overflow Vulnerability in Natlimit Function

A critical stack-based buffer overflow vulnerability has been identified in the Tenda FH1202 router, specifically in version 1.2.0.14(408). The issue arises in the 'fromNatlimit' function within the '/goform/Natlimit' file, where the 'page' parameter can be manipulated, leading to a stack-based overflow. This vulnerability can be exploited remotely, and a public exploit is available.

Impact

Exploitation of this vulnerability causes a stack-based buffer overflow, which can lead to arbitrary code execution or other unintended behavior by overwriting the return address of a function on the stack.
