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

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run PTZOptics PT30X-SDI/NDI Cameras. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-11-04, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-11-25; treat that as the outer limit, not the target.
• EPSS 58.8%, percentile 99: FIRST’s model estimates a 58.8% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.

What it is

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.

CISA’s summary

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.

Weakness type: CWE-306, CWE-287.
