A local access elevation of privilege issue has been identified and resolved in the Symantec Altiris Deployment Solution Client GUI. Successful exploitation could result in unauthorized local system access on a client system.

Affected Products

ProductVersionBuildSolution(s)
Altiris Deployment Solution6.XAll6.9.355 SP1

Details

Brett Moore, Insomnia Security, identified Altiris Deployment Solution agents as susceptible to a privilege escalation vulnerability taking advantage of windows messaging to bypass client security settings in the Client GUI. Successful exploitation could lead to an authorized but non-privileged user potentially leveraging local system access on the targeted client system.

  • Select either "Deployment Solution for Clients 6.9 SP1" or “Deployment Solution for Servers 6.9 SP1” from the drop-down box
  • Accept the "End User License Agreement"
  • Login to the download site

Follow the installation instructions 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
