Detailsinfo

A vulnerability classified as critical has been found in Symantec Endpoint Protection Manager 11/12 (Anti-Malware Software). This affects an unknown functionality of the component SAP XML Parser. The manipulation with an unknown input leads to a xml external entity reference vulnerability. CWE is classifying the issue as CWE-611. The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The management console in Symantec Endpoint Protection Manager (SEPM) 11.0 before 11.0.7405.1424 and 12.1 before 12.1.4023.4080, and Symantec Protection Center Small Business Edition 12.x before 12.1.4023.4080, allows remote attackers to read arbitrary files via XML data containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

The weakness was released 02/13/2014 by Stefan Viehböck and Johannes Greil with SEC Consult as SYM14-004 as confirmed advisory (Website). The advisory is shared at symantec.com. This vulnerability is uniquely identified as CVE-2013-5014 since 07/29/2013. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Chris Graham (cgrahamseven) in Python and been published 2 weeks after the advisory. The exploit is shared for download at exploit-db.com. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 72542 (Symantec Endpoint Protection Manager < 11.0 RU7-MP4a / 12.1 RU4a Multiple Vulnerabilities (SYM14-004)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows. The commercial vulnerability scanner Qualys is able to test this issue with plugin 121808 (Symantec Endpoint Protection Manager Multiple Vulnerabilities (SYM14-004)). The ISC announces an increase of scan attempts of the affected ports: "Last week, we mentioned a new vulnerability in Symantec Endpoint Protection Management [1]. According to Symantec's advisory, this product listens on port 9090 and 8443/TCP. Both ports are scanned regularly for various vulnerabilities, in particular 8443, being that it is frequently used by web servers as an alternative to 443. However, on February 7th, we detected a notable increase in scans for both ports."

Upgrading to version 11.0 RU7-MP4a (11.0.7405.1424) or 12.1 RU4a (12.1.4023.4080) eliminates this vulnerability. The upgrade is hosted for download at symantec.flexnetoperations.com.It is possible to mitigate the weakness by firewalling tcp/9090 (http) / tcp/8443 (https). The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

Blocking port 9090 will deny access to online help and other web-based features. Blocking port 8443 will deny access to all remote consoles, replication, and Symantec Network Access Control Enforcer communication. Administrators may configure firewall rules to allow access to port 9090 or 8443 from explicit hosts or IP addresses to enable these features.
Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 13706.

The vulnerability is also documented in the databases at X-Force (91102), Exploit-DB (31853), Tenable (72542), SecurityFocus (BID 65466†) and OSVDB (103305†). Further details are available at zdnet.com. Entry connected to this vulnerability is available at VDB-12322.
