| Título | D-Link DIR-825 Rev.B 2.10 Stack-based Buffer Overflow |
|---|
| Descripción | A stack-based buffer overflow vulnerability exists in the httpd web server of D-Link DIR-825 routers with firmware version Rev.B 2.10. A remote, unauthenticated attacker can exploit this to cause a denial of service.
The vulnerability is triggered when an attacker sends a request to the switch_language.cgi endpoint with an overly long string in the language parameter. This string is saved to the device's NVRAM. When a page that uses this language setting (like login.asp) is subsequently loaded, the server reads the malicious string from NVRAM and copies it into a small stack buffer without proper size validation, leading to an overflow and crashing the server. |
