Summary

Atlas Copco Power Focus 6000 devices (all versions) contain information disclosure and session hijacking vulnerabilities (CWE-312, CWE-334, CWE-319). The vulnerabilities allow unauthenticated attackers with network access to capture sensitive configuration or credential data and hijack active user sessions. Successful exploitation results in loss of sensitive information and unauthorized takeover of an operator's active session. Atlas Copco has not provided patches or committed to remediation. No public exploits are currently known, but attack complexity is low.

What this means
What could happen
An attacker with network access could intercept sensitive configuration or credential information from the Power Focus 6000 and potentially take control of an operator's active session, allowing unauthorized changes to power distribution settings or monitoring.
Who's at risk
Power utilities and energy facilities operating Atlas Copco Power Focus 6000 power supply or power management systems should prioritize this. Any organization using the Power Focus 6000 in a critical power control or distribution role needs to assess exposure and apply compensating controls immediately.
How it could be exploited
An attacker on the network (or via internet if the device is exposed) can intercept unencrypted communications between a user and the Power Focus 6000 to capture session tokens or sensitive data. With a captured session token, the attacker can masquerade as the legitimate user and issue commands to the device without needing to authenticate.
Prerequisites
  • Network path to the Power Focus 6000 device
  • Ability to intercept network traffic (MITM position or compromised network segment)
  • User must be actively logged into the device for session hijacking
