This advisory relates to SYM11-009 which accurately addressed the
vulnerabilities in versions listed at the time. The new assessment shows that
Symantec Endpoint Protection 12.1 is also impacted. This advisory is ONLY for

Details Symantec was notified of a cross-site scripting and cross-site request
forgery vulnerability within the Symantec Endpoint Protection Manager 12.1.

exploitations, they generally require enticing a previously authenticated user
to click on a link in a context such as a website or in an email.

of the link it is possible for the URL to execute arbitrary html requests and
scripts in the context of the targeted user

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
