Cross-site Request Forgery Issues

Symantec's Data Loss Prevention (DLP) Management Console is potentially 
susceptible to persistent cross-site scripting (XSS) issues and a possible 
cross-site request forgery (CSRF) in the Enforce Server administration 
console. Successful exploitation could result in potential unauthorized 
actions directed against the console potentially with elevated privileges.

Symantec was notified of XSS issues as well as possible CSRF issues within the
Symantec Data Loss Prevention Enforce Server administration console. 
Additionally, Symantec DLP engineers have been doing extensive internal 
reviews that identified and addressed other areas susceptible to similar 

Both XSS and CSRF issues are the result of insufficient validation/sanitation
of user input and server output. A successful exploitation of these issues in
Enforce Server administration console pages used to manage DLP is possible 
should a properly authenticated user click on a maliciously-crafted link. 
Depending on the nature of the link it is possible for execution of arbitrary
html requests and scripts in the context of the targeted user. The 
administration console normally allows access to only specified 
users/administrators with varying levels of access depending on their 

Cross-site scripting and cross-site request forgery are trust exploitations 
requiring enticing a previously authenticated user to click on a link in a 
context such as a website URL or an HTML email. To be exposed to other than 
another authorized network user, an external attacker would need to 
successfully entice an authorized, privileged or limited-access Enforce Server
console user to visit a malicious web site or click on a malicious HTML link 
in an email in any attempts to take advantage of this issue.

In a typical installation the Symantec Data Loss Prevention Enforce Server 
administration console should not be accessible external to the network 
environment and access should be restricted to specified users/administrators.
Web browsers used by authorized users to manage Symantec Data Loss Prevention
Enforce Server should never be used for casual browsing of external web sites
during an active administrative session. These restrictions greatly reduce 
exposure to external attempts of this type.

Symantec Response

Symantec engineers have verified and addressed these external submissions as 
well as those identified through internal reviews. Symantec strongly 
recommends Symantec Data Loss Prevention customers update to the latest 
release of Symantec Data Loss Prevention as indicated in the above product 
table. Symantec knows of no exploitation of or adverse customer impact from 
these issues.

Symantec Data Loss Prevention 12.5.2 and 14.0 are currently available through
customer normal download channels.


Since exploitation depends on user interaction (phishing, clicking on 
untrusted html link), customers are strongly encouraged to follow security 
best practices.

Specifically, during an active DLP administration session:

Avoid casual surfing in different tabs of the browser session

Avoid clicking html links in emails or any other electronic document that may
launch an additional browser instance

Best Practices

Symantec strongly recommends as part of normal best practices:

Restrict access to administration or management systems to privileged users.

Avoid casual surfing in different tabs when using the browser to administer 

Do not click on html links in emails.

Disable remote access if not required or restrict it to trusted/authorized 
systems only.

Where possible, limit exposure of application and web interfaces to 
trusted/internal networks only.

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 


Symantec would like to thank Mike Czumak (@SecuritySift) for reporting XSS and
CSRF issues; Pieter Hiele for reporting XSS issues and both for coordinating 
with us as we resolved them.
