CyberRota Analysis
AI-GeneratedCompactLogix® 5380, ControlLogix® 5580, and EN4 communication modules are vulnerable due to improper handling of revoked certificates in CIP Security, allowing attackers to exploit this flaw. This could enable unauthorized network access by accepting untrusted certificates, thereby undermining the integrity of security measures. Organizations using these products should prioritize addressing this vulnerability to safeguard their network infrastructure against potential exploitation.
Original NVD Description
A security issue exists within CompactLogix® 5380, ControlLogix® 5580, and EN4 communication modules related to CIP Security certificate revocation handling. The security issue stems from the controller failing to properly reject certificates signed by an intermediate certificate that has been revoked via a Certificate Revocation List (CRL). This could allow a network-based attacker to establish a connection using a certificate that should be untrusted, potentially bypassing CIP Security protections.
