| Title | D-Link DIR-825 R Denial of Service |
|---|
| Description | A stack-based buffer overflow vulnerability exists in the web service of the D-Link DIR-825 router, firmware version Rev.B 2.10. The vulnerability is triggered when an authenticated attacker sends a POST request to ping_response.cgi with an overly long string in the ping_ipaddr parameter. Inside the parse_special_char function, this string is copied into a fixed-size stack buffer using strcpy without proper length validation. This action overwrites the stack, causing the httpd service to crash upon the function's return and resulting in a remote Denial of Service (DoS). |
