From this webpage screenshot, the following key information about the vulnerability can be obtained: Vulnerability Overview Device and Firmware Version: Multiple firmware versions of Tenda AC6V2.0 V15.03.06.23 contain a buffer overflow vulnerability. Affected Function: Vulnerability Details 1. Parameter Issue Description: Users can trigger the vulnerability by sending a POST request containing the parameter. This parameter is passed to the function, causing a buffer overflow. Example Code: Exploitation Method: By crafting a specific value for , attackers can overwrite other data in memory, potentially leading to program crashes or arbitrary code execution. 2. Parameter Issue Description: Users can trigger the vulnerability by sending a POST request containing the parameter. This parameter is passed to the function, causing a buffer overflow. Example Code: Exploitation Method: By crafting a specific value for , attackers can overwrite other data in memory, potentially leading to program crashes or arbitrary code execution. 3.

Parameter Issue Description: Users can trigger the vulnerability by sending a POST request containing the parameter. This parameter is passed to the function, causing a buffer overflow. Example Code: Exploitation Method: By crafting a specific value for , attackers can overwrite other data in memory, potentially leading to program crashes or arbitrary code execution. Summary These vulnerabilities arise from insufficient boundary checking and length validation when processing user input, resulting in the function copying excessively long strings into fixed-size buffers, thereby causing buffer overflows. Attackers can exploit these vulnerabilities to manipulate the behavior of affected devices, including executing arbitrary code.
