Descriptions

A stack-based buffer-overflow exists in Edimax IP-Camera IC-3116W (v3.06) and IC-3140W (v3.07), which allows an unauthenticated, unauthorized attacker to perform remote-code-execution due to a crafted GET-Request. The overflow occurs in binary ipcam_cgi due to a missing type check in function doGetSysteminfo(). This has been fixed in version: IC-3116W v3.08.

Se presenta un desbordamiento de búfer en la región stack de la memoria en la Cámara IP Edimax IC-3116W (versión v3.06) e IC-3140W (versión v3.07), que permite a un atacante no autorizado y no autenticado llevar a cabo una ejecución de código remota debido a una petición GET diseñada. El desbordamiento ocurre en el binario ipcam_cgi debido a una falta de comprobación de tipo en la función doGetSysteminfo(). Esto ha sido corregido en la versión: IC-3116W v3.08
