Vulnerability from github – Published: 2026-06-26 09:30 – Updated: 2026-06-26 09:30

Details

An unauthenticated NULL pointer dereference vulnerability exists in IEEE8021x_upload.cgi in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by improper validation of multipart upload headers when processing certificate-related upload fields. A remote attacker may exploit this vulnerability by sending a malformed multipart request, causing the affected CGI process to crash and resulting in a denial of service.

Severity

7.5 (High)
