Overview
Symantec's Enterprise Security Manager (ESM) for Windows has an unquoted search
path in the Manager and Agent components. This could allow a non-privileged
local user, able to successfully insert arbitrary code in the root path, to
potentially execute their code with elevated privileges during system startup
or reboot.

Details
Symantec was notified of an unquoted search path issue impacting the ESM
manager and agents for Windows deployed as part of Symantecs Enterprise
Security Manager. This could potentially allow an authorized but non-
privileged local user to execute arbitrary code with elevated privileges on the
system. A successful targeting attempt would require the local user to be able
to insert their code in the system root path undetected by the OS or other
security applications where it could potentially be executed during application
startup or reboot. If successful, the local users code would execute with the
elevated privileges of the application.
Symantec Response
Symantec product engineers verified the reported issue and have released
Security Update SU44 to address this issue.
A patched MSI installer for 10.0 agents is also available for new agent
installations if upgrade to 11.0 isnt possible at this time. Go to
https://www.symantec.com/security_response/securityupdates/list.jsp?fid=esm&pvid=pu
to download the updated installer
Symantec is not aware of exploitation of or adverse customer impact from this
issue.
Update Information
Download SU44 via LiveUpdate or from the SU44 link provided
Once SU44 is applied,
Run the Check ESM Service ImagePath check
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
