Technical description

The session hijacking attack targets the application layer's control mechanism, which manages authenticated sessions between a host PC and a PLC. During such sessions, a session key is utilized to maintain security. However, if an attacker captures this session key, they can inject traffic into an ongoing authenticated session. To successfully achieve this, the attacker also needs to spoof both the IP address and MAC address of the originating host which is typical of a session-based attack.

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.
