CVE-2024-8956Known exploitationPublic exploitNetwork attack vector

Configuration disclosure and modification via unauthenticated CGI

Published Sep 17, 2024 · Updated Nov 22, 2025

Authentication bypass in PTZOptics PT30X-SDI and PT30X-NDI-xx cameras before 6.3.40 allows remote attackers to read and alter configuration. The lighttpd web server passes requests lacking an HTTP Authorization header to /cgi-bin/param.cgi, which returns usernames, password hashes, network settings, and device details and accepts configuration writes. Network access to the camera web interface is sufficient; attackers can expose credentials or replace individual settings and complete configuration files.
