| タイトル | D-Link DIR-513 v1.0 Buffer Overflow |
|---|
| 説明 | A stack-based buffer overflow vulnerability exists in the function formLanguageChange of the Boa web server, which is used to implement the web-based management interface in the DIR-513 embedded device.
This vulnerability is triggered when a remote attacker sends a specially crafted POST request to the endpoint /goform/formLanguageChange. The vulnerable function retrieves the parameter curTime from the request body and then uses it in a call to sprintf():
sprintf(v12, "%s?t=%s", "/index.asp", v8);
Here, v8 is derived from the input curTime . Since the length of curTime is not properly validated before being used in sprintf, an attacker can supply an excessively long value, leading to a stack buffer overflow. |
