Overview
The management console in Symantec Endpoint Protection Manager (SEPM) and
Symantec Protection Center (SPC) for SEP 12.0 Small Business Edition, contains
PHP scripts that do not provide proper validation to external input. This
could potentially result in remote code execution.
Symantec Network Access Control (SNAC) contains an unquoted search path that
could potentially permit local code execution and possible elevation of
privilege.

Details
Symantec was notified of vulnerabilities in the PHP scripts in the Symantec
Endpoint Protection Manager (Symantec Protection Center for SEP 12.0 Small
Business Edition). Insufficient validation is done on external input to these
scripts. This could allow an unauthorized user who is able to access the
console to potentially execute arbitrary code with application privileges.
Symantec Network Access Control, shipped as an optional add-on to Symantec
Endpoint Protection, contains an unquoted search path that could allow a local
user to execute arbitrary code. The local user would need to be able to place
their executable in the root path to be executed during application startup.
In a recommended installation, the Symantec Endpoint Protection Manager, or
Symantec Protection Center, should be hosted behind the corporate firewall with
restricted external access. Normal access to the system hosting SEPM or SPC
should be restricted to privileged users as a security best practice. If it is
necessary to deploy SEPM or SPC outside the corporate network, Symantec
strongly recommends configuring client/server communication only and blocking
all access to the management console.
Symantec Response
Symantec product engineers verified the reported issues and resolved these
issues in the Symantec Endpoint Protection or Symantec Network Access Control
releases identified above.
Update Information
Updates are 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
