Vulnerability Title
GV-LPC2011/LPC2211 - unauthorized null pointer dereference vulnerability in packet parsing
Source: CVE Program / CVE List V5
Vulnerability Description
An unauthenticated
NULL pointer dereference vulnerability exists in the HTTP request parsing logic
of multiple CGI components in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and
earlier. The vulnerability is caused by improper validation of required HTTP
request metadata before it is used by the affected components. A remote attacker
may exploit this vulnerability by sending a specially crafted HTTP request,
causing the affected process to crash and resulting in a denial of service.
