Symantec Altiris Notification Server Agent GUI Local Elevation of Privilege

Revision History


Remote AccessNo
Local AccessYes
Authentication RequiredYes
Exploit publicly availableNo

A non-privileged user can leverage the Symantec Altiris Notification Server Agent Graphical User Interface (GUI) to gain privileged access to the system.

Affected Products
Altiris Notification Server Agent6.XAll6.0 SP3 R8

Note: This issue impacts the client-side agent only and does require local authenticated access.

Insomnia Security notified Symantec that there was a local elevation of privilege vulnerability in the Altiris Notification Server Agent GUI. By successfully leveraging the issue, authorized but non-privileged users on a local system could potentially gain unauthorized, elevated access to that system.

Symantec Response
Symantec engineers have verified the vulnerability does exist in versions of the Altiris Notification Server Agent listed above and released an update to resolve this issue.
Symantec knows of no exploitation of or adverse customer impact from these issues.

The update to resolve this issue can be obtained as follows:

  1. Go to http://kb.altiris.com/
  2. Search for KB 39159.
  3. Select KB link and follow the directions to download SP3 R8.
  4. After downloading the file, execute and follow the installer instructions to upgrade Notification Server.

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.

Symantec would like to thank Brett Moore of Insomnia Security for reporting this issue and for providing full coordination while Symantec resolved it.
