  2. Vulnerabilities (CVE)
  3. CVE-2012-10021
A stack-based buffer overflow vulnerability exists in D-Link DIR-605L Wireless N300 Cloud Router firmware versions 1.12 and 1.13 via the getAuthCode() function. The flaw arises from unsafe usage of sprintf() when processing user-supplied CAPTCHA data via the FILECODE parameter in /goform/formLogin. A remote unauthenticated attacker can exploit this to execute arbitrary code with root privileges on the device.

Summary
  • (es) Existe una vulnerabilidad de desbordamiento de búfer en la pila en las versiones de firmware 1.12 y 1.13 del D-Link DIR-605L Wireless N300 Cloud Router mediante la función getAuthCode(). La falla se debe al uso inseguro de sprintf() al procesar datos CAPTCHA proporcionados por el usuario mediante el parámetro FILECODE en /goform/formLogin. Un atacante remoto no autenticado puede explotar esto para ejecutar código arbitrario con privilegios de root en el dispositivo.
