Security Advisories Relating to Symantec Products - Symantec Encryption 
Management Server Web Email Protection XSS


July 22, 2013



CVSS2		Impact	Exploitability	CVSS2 Vector
Base Score	
Symantec Encryption Management Server Web Email Protection XSS  - Medium
6.0		6.4	6.8		AV:N/AC:M/AU:S/C:P/I:P/A:P


Symantec's Encryption Management Server, previously PGP Universal Server, is 
susceptible to a cross-site scripting (XSS) issue, in the web management 
interface of the server.  The XSS issue is in the Web Email Protection 
component. This issue could allow an authenticated Web Email Protection user to
run arbitrary scripts in the context of the management console.

Affected Products

Product		Symantec Encryption Management Server / Symantec PGP Universal 
Version		3.3.0 MP1 and prior
Build		All
Solution(s)	Symantec Encryption Management Server 3.3.0 MP2

Products Not Affected

Product		Symantec Encryption Management Server
Version		3.3.0 MP2


Symantec was notified of an XSS issue existing in the Symantec Encryption 
Management Server web management interface.  The issue is in the Web Email 
Protection component. Web Email Protection does not properly sanitize 
user-submitted HTML, which could allow arbitrary script to run in the context 
of the management console. A malicious individual would require either an 
authenticated Web Email Protection account, or be able to entice an 
authenticated Web Email Protection user to submit a specifically-configured 
encrypted email attachment.  Interaction with the attached code during 
decryption and viewing could trigger the arbitrary code.  Successful 
exploitation could potentially result in disclosure of or unauthorized access 
to, sensitive information on the server.

Symantec Response
Symantec validated this issue in earlier versions of Symantec PGP Universal 
Server/Encryption Management Server.  Symantec Encryption Management Server 
3.3.0 MP2 is not vulnerable to this issue. 

Symantec is not aware of exploitation of or adverse customer impact from this issue.

Update Information

Updates are available through customers' normal download locations.

Best Practices
As part of normal best practices, Symantec strongly recommends that customers:

    Restrict access of administration or management systems to privileged 

    Restrict remote access, if required, to trusted/authorized systems only.

    Run under the principle of least privilege where possible to limit the 
    impact of exploit by threats.

    Keep all operating systems and applications updated with the latest vendor 

    Follow a multi-layered approach to security. Run both firewall and 
    anti-malware applications, at a minimum, to provide multiple points of 
    detection and protection to both inbound and outbound threats.

    Deploy network and host-based intrusion detection systems to monitor 
    network traffic for signs of anomalous or suspicious activity. This may aid
    in detection of attacks or malicious activity related to exploitation of 
    latent vulnerabilities
