Technical details
A stack-based buffer overflow exists in the TENDA_HTTPD binary of the Tenda PW201A v1.0.5. The vulnerability is located in the SafeMacFilter handler function (address 0x42e6a4), where the 'page' HTTP parameter is retrieved via websGetVar and subsequently passed to sprintf without bounds checking into a fixed-size stack buffer (acStack_120). An unauthenticated remote attacker can exploit this by sending a crafted HTTP request with an overly long 'page' parameter, leading to a process crash and Denial of Service. No patch is currently mentioned in the advisory.
