# PTZOptics PT30X-SDI/NDI-xx before firmware 6.3.40 is vulnerable to an insufficient authentication issue

PTZOptics PT30X-SDI/NDI cameras have an authentication bypass in the /cgi-bin/param.cgi endpoint. A remote attacker can reach camera settings without logging in, and combined with CVE-2024-8957 can run code as root.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:PTZOptics PT30X-SDI/NDI Cameras affected ? fixed ?
- vendor:ptzoptics pt30x-sdi firmware affected < 6.3.40 fixed 6.3.40
- vendor:ptzoptics pt30x-ndi-xx-g2 firmware affected < 6.3.40 fixed 6.3.40

## Fix

Apply the mitigations from the vendor per CISA guidance, or discontinue use of the product if no mitigation is available.

## From the sources

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.
