CVE-2024-8956
PTZOptics PT30X-SDI/NDI cameras contain an insecure direct object reference (IDOR) vulnerability that allows a remote, attacker to bypass authentication for the /cgi-bin/param.cgi CGI script. If combined with CVE-2024-8957, this can lead to remote code execution as root.
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.
