CISA ICS Advisory: Zoneminder

Here’s what this advisory affects, and what to do about it.

Successful exploitation of this vulnerability could result in full Remote Code Execution (RCE) as the web server user.

On August 25, 2026, the Cybersecurity and Infrastructure Security Agency (CISA) released an ICS advisory detailing a vulnerability in ZoneMinder, an open-source video surveillance software platform commonly used in industrial control systems and physical security environments.

Remote code execution via web server

The advisory indicates that successful exploitation of the flaw could result in full remote code execution (RCE) as the web server user. CISA has not stated whether the vulnerability has been exploited in the wild.

Affected products

The advisory concerns ZoneMinder. It does not specify particular version numbers or a precise list of affected releases. No specific sectors beyond organisations using the software for surveillance and industrial monitoring are named.

What to do

Determine whether any ZoneMinder instances are present in your environment or supply chain.
Review the vendor’s official repository and release notes for patches addressing this issue.
Apply available updates from the ZoneMinder project as soon as they are released.
Implement network segmentation and least-privilege controls for any web-facing surveillance management interfaces.
Monitor CISA’s advisory page and the ZoneMinder project’s security channel for further updates.

Organisations operating industrial control systems or critical infrastructure should treat unauthenticated remote code execution flaws in video surveillance platforms as high priority due to the potential for lateral movement and persistent access.
