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.
Product Version Solution(s)
Symantec Data Loss Prevention 12.5.1 and prior Migrate to Symantec Data
Loss Prevention 12.5.2 or
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 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
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
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
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
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
