CVE-2012-6441: Rockwell Automation ControlLogix PLC Information Exposure

An information exposure of confidential information results when the device receives a specially crafted CIP packet to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP. Successful exploitation of this vulnerability could cause loss of confidentiality. Rockwell Automation EtherNet/IP products; 1756-ENBT, 1756-EWEB, 1768-ENBT, and 1768-EWEB communication modules; CompactLogix L32E and L35E controllers; 1788-ENBT FLEXLogix adapter; 1794-AENTR FLEX I/O EtherNet/IP adapter; ControlLogix 18 and earlier; CompactLogix 18 and earlier; GuardLogix 18 and earlier; SoftLogix 18 and earlier; CompactLogix controllers 19 and earlier; SoftLogix controllers 19 and earlier; ControlLogix controllers 20 and earlier; GuardLogix controllers 20 and earlier; and MicroLogix 1100 and 1400

Security readout for executives and security teams

This vulnerability can let an unauthenticated network attacker read confidential information from certain Rockwell Automation EtherNet/IP and Logix-family industrial devices. The cited impact is confidentiality loss only, not direct code execution or process disruption. It matters most where these legacy control systems are reachable from untrusted networks. Exposure is most likely in OT networks using listed Rockwell Automation EtherNet/IP modules, Logix controllers, MicroLogix 1100/1400, or related adapters with CIP services reachable over IP. Treat as a moderate OT confidentiality risk. Prioritize environments where legacy Rockwell control assets are reachable from corporate, vendor remote-access, or internet-connected paths. Mitigation focus: Identify listed Rockwell Automation devices and firmware versions in OT asset inventory.; Review Rockwell Automation and CISA advisories for product-specific fixes or mitigations.; Restrict TCP/UDP 2222 and 44818 to trusted OT and engineering hosts..
