Symantec Endpoint Protection Manager Input Validation Hole Permits Cross-Site Scripting and Cross-Site Request Forgery Attacks
SecurityTracker Alert ID:  1025919
SecurityTracker URL:  http://securitytracker.com/id/1025919
CVE Reference:   CVE-2011-0550, CVE-2011-0551   (Links to External Site)
Updated:  Jan 25 2012
Original Entry Date:  Aug 11 2011
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  
Version(s): 11.0 RU6(11.0.600x), 11.0 RU6-MP1(11.0.6100), 11.0 RU6-MP2(11.0.6200), 11.0 RU6-MP3(11.0.6300)
Description:   Two vulnerabilities were reported in Symantec Endpoint Protection Manager. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks.

A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Symantec Endpoint Protection Manager software 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.

Sow Ching Shiong (via Secunia Labs) reported both vulnerabilities. Sachin Shinde(Cons0ul) also reported the cross-site scripting vulnerability.

[Editor's note: The vendor originally reported that Symantec Endpoint Protection version 12.x is not affected. In January 2012, the vendor issued advisory SYM12-001 to report that version 12.1 is indeed affected.]

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Symantec Endpoint Protection Manager software, 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.
Solution:   The vendor has issued a fix (SEP 11 RU7, SEP 12.1 RU1).
