CVE Reference:   CVE-2014-3437, CVE-2014-3438, CVE-2014-3439   (Links to External Site)
Date:  Nov 7 2014
Impact:   Denial of service via network, Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of system information, Modification of user information, User access via network

Description:   Several vulnerability was reported in Symantec Endpoint Protection Manager. A remote user can conduct cross-site scripting attacks. A remote user can obtain potentially sensitive information. A remote user can overwrite files on the target system.

The management console does not properly filter HTML code from user-supplied input before displaying the input [CVE-2014-3438]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the Symantec Endpoint Protection Manager console 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.

A remote user can exploit a flaw in the ConsoleServlet logging component to overwrite the log file and possibly other files, causing denial of service conditions or leading to remote user access [CVE-2014-3439].

A remote user can supply XML data with a specially crafted XML External Entity (XXE) reference to obtain potentially sensitive information from the server [CVE-2014-3437].

Stefan Viehbock with SEC Consult Vulnerability Lab reported several vulnerabilities. Inaki Rodriguez (@virtualminds_es) reported one vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the Symantec Endpoint Protection Manager console, 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.

A remote user can obtain potentially sensitive information.

A remote user can overwrite files on the target system.

Solution:   The vendor has issued a fix (12.1 RU5).
