Overview
Symantec Endpoint Protection Manager 12.1 web console is susceptible
to cross-site scripting and cross-site request forgery that could potentially
lead to arbitrary code execution.
Affected Products
Product Version Build Solution(s)
Symantec Endpoint Protection 12.1 All SEP 12.1 RU1 (12.1.1000)
Notes
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
SEP 12.1. No other versions are impacted.
Details Symantec was notified of a cross-site scripting and cross-site request
forgery vulnerability within the Symantec Endpoint Protection Manager 12.1.
Because both cross-site scripting and cross-site request forgery are trust
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.
A successful exploitation of these issues is possible once a properly
authenticated user clicks on a specially crafted link. Depending on the nature
of the link it is possible for the URL to execute arbitrary html requests and
scripts in the context of the targeted user
Symantec Response Symantec product engineers verified the reported issues.
Symantec engineers fixed the issues in Symantec Endpoint Protection 12.1 RU1.
Symantec knows of no exploitation of or adverse customer impact from these
issues.
Update Information
Updates will be available through customers' normal support/download
locations.
Best Practices
As part of normal best practices, Symantec strongly recommends:
Restrict access to administration or management systems to privileged
users.
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
patches. 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
Credit Symantec credits Ivan Markovic working through Secunia Labs for
identifying these issues and coordinating with Symantec as we resolved them.
