CVE-2024-8956: PTZOptics PT30X-SDI/NDI Cameras Authentication Bypass Vulnerability

CVE-2024-8956 is rated critical with a CVSS v3.1 base score of 9.1 and affects PTZOptics PT30X-SDI/NDI Cameras, along with 2 other products in NVD’s configuration data. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-11-04, which means exploitation in the wild has been observed.

Vulnerability description

PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an insufficient authentication issue. The camera does not properly enforce authentication to /cgi-bin/param.cgi when requests are sent without an HTTP Authorization header. The result is a remote and unauthenticated attacker can leak sensitive data such as usernames, password hashes, and configurations details. Additionally, the attacker can update individual configuration values or overwrite the whole file.
