Summary

A vulnerability in Johnson Controls Illustra Essentials Gen 4 IP cameras allows an authenticated user with administrator privileges to recover stored credentials for other Linux user accounts on the device. The vulnerability exists in firmware versions up to Illustra.Ess4.01.02.10.5982 and is addressed in firmware version Illustra.Ess4.01.02.13.6953 or later.

What this means
What could happen
An authenticated attacker with admin privileges on an Illustra Essentials Gen 4 camera could extract stored credentials for other Linux users on the device, potentially granting access to other systems or functions within the camera.
Who's at risk
Building automation operators and security staff managing Johnson Controls Illustra Essentials Gen 4 IP cameras in commercial buildings, hospitals, data centers, and industrial facilities should be aware of this issue. Affected are camera systems running firmware versions up to Illustra.Ess4.01.02.10.5982.
How it could be exploited
An attacker with valid admin credentials for the camera management interface could query or read credential storage on the device to recover plaintext or weakly-protected credentials for other Linux user accounts. This requires direct access to the management interface (web UI or API).
Prerequisites
  • Valid administrator credentials for the Illustra Essentials Gen 4 camera
  • Network access to the camera's management interface (port 80/443 or similar)
  • Knowledge of or access to the credential storage mechanism on the device
