PTZOptics PT30X-SDI/NDI Cameras Authentication Bypass

Published Updated By the CyberSecBulletin desk

CVE-2024-8956 is a critical-severity improper authentication vulnerability in PT30X-SDI from PTZOptics, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.3.40 as the first without the flaw, so updating PT30X-SDI to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on November 4, 2024, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update PT30X-SDI to 6.3.40 or a later version.
  2. Update PT30X-NDI to 6.3.40 or a later version.
  3. Update pt30x-sdi_firmware to 6.3.40 or a later version.
  4. CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official 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.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
