Description A buffer overflow issue exists in the router's web server, specifically in the httpd. The problem arises when processing the deviceList parameter for a post request. The value of this parameter is directly used in a strcpy to a local variable on the stack, which overrides the return address of the function.

For Tenda AC9 version 15.03.05.19(6318) CN, update the firmware to a version that addresses this issue.
