CVE-2024-8957 PTZOptics PT30X-SDI/NDI Cameras OS Command Injection Vulnerability
PTZOptics PT30X-SDI/NDI cameras contain an OS command injection vulnerability that allows a remote, authenticated attacker to escalate privileges to root via a crafted payload with the ntp_addr parameter of the /cgi-bin/param.cgi CGI script.
From the CISA KEV catalogue version 2026.11.06, with Cybergen analysis. Updated 6 Nov 2026.
Should You Worry?
- CISA confirmed exploitation in the wild and added it to the Known Exploited Vulnerabilities catalogue on 4 Nov 2024.
- Rated High severity (CVSS 7.2, scored by Vendor).
- It has been in the catalogue for 732 days. Systems still unpatched now have almost certainly been scanned for it.
What It Is
PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an OS command injection issue. The camera does not sufficiently validate the ntp_addr configuration value which may lead to arbitrary command execution when ntp_client is started. When chained with CVE-2024-8956, a remote and unauthenticated attacker can execute arbitrary OS commands on affected devices.
