This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

ZoneMinder is a free, open source closed-circuit television software application. Prior to 1.39.2, 1.38.2, and 1.36.40, ZoneMinder interpolates an unvalidated monitor Device field into shell commands in PHP and Perl control paths when an authenticated user with monitor-create or monitor-edit permission saves a Local monitor whose Device Path contains shell metacharacters and the monitor control or startup path runs. In this attack mechanism, the stored Device value reaches Perl qx() and backtick execution before zmdc.pl argument detainting, while separate PHP command paths use bypassable escapeshellcmd defenses. The attacker can execute arbitrary commands as the web server user. This vulnerability is fixed in 1.39.2, 1.38.2, and 1.36.40.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
