A buffer overflow vulnerability has been discovered in Tenda Ac15 V15.13.07.13. The vulnerability occurs when the webCgiGetUploadFile function calls the socketRead function to process HTTP request messages, resulting in the overwriting of a buffer on the stack.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
