Eaton Cooper Power Systems ProView 4.0 and 5.0 before 5.0 11 on Form 6 controls and Idea and IdeaPLUS relays generates TCP initial sequence number (ISN) values linearly, which makes it easier for remote attackers to spoof TCP sessions by predicting an ISN value.

Remedy

Eaton’s Cooper Power Systems division has developed ProView 5.0 Revision 11 software that mitigates this vulnerability, and the Form 6 control version was released on June 12, 2015. Idea/IdeaPLUS relay ProView software versions began to be posted on June 30, 2015. ProView 5.0 Revision 11 will be compatible with any hardware and firmware Versions 5.0 and higher. Versions below 5.0 may be updated with the appropriate and corresponding hardware upgrades. Information on how to obtain and install these available remedies is available at: http://www.cooperindustries.com/content/public/en/power_systems/resources/securitysupport.html For additional technical information, please contact Eaton’s Cooper Power Systems at: https://www.eaton.com/cybersecurity
