Rockwell Automation CompactLogix Input Validation Flaw Lets Remote Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1035190
SecurityTracker URL:  http://securitytracker.com/id/1035190
CVE Reference:   CVE-2016-2279   (Links to External Site)
Date:  Mar 4 2016
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Rockwell Automation CompactLogix (EtherNet/IP). A remote user can conduct cross-site scripting attacks.

The CompactLogix web server does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the web server and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

The following models are affected:

1769-L16ER-BB1B, Version 27.011 and prior
1769-L18ER-BB1B, Version 27.011 and prior
1769-L18ERM-BB1B, Version 27.011 and prior

1769-L30ER, Version 27.011 and prior
1769-L30ERM, Version 27.011 and prior
1769-L30ER-NSE, Version 27.011 and prior
1769-L33ER, Version 27.011 and prior
1769-L33ERM, Version 27.011 and prior
