|
Description: |
Symantec was notified of an unquoted search path issue impacting the EEDService deployed in Symantec Endpoint Encryption. An authorized but non-privileged local user could potentially leverage this issue to execute arbitrary code with elevated privileges on the system. A successful 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/settings where it could potentially be executed during application startup or reboot. If successful, the local user's code would execute with the elevated privileges of the application. |
MITIGATION
Symantec Response
Symantec engineers verified this issue and have resolved it in Symantec Endpoint Encryption 11.1.1. Symantec is not aware of exploitation of or adverse customer impact from this issue.
Update Information
Update to SEE 11.1.1 will be available through Symantec File Connect. Customers should apply this update to avoid potential incidents of this nature.
Best Practices
Symantec strongly recommends as part of normal best practices:
- 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.
