PTZOptics PT30X-SDI/NDI Cameras OS Command Injection
CVE-2024-8957 is a high-severity improper neutralization of special elements used in an OS command vulnerability in PT30X-SDI from PTZOptics, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, 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.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update PT30X-SDI to 6.3.40 or a later version.
- Update PT30X-NDI to 6.3.40 or a later version.
- Update pt30x-sdi_firmware to 6.3.40 or a later version.
- CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Official description
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.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
