Overview

Symantec’s Altiris Deployment Solution and Notification Server web consoles install a vulnerable ActiveX control. Exploitation of this issue could possibly lead to unauthorized information disclosure, system information corruption or potentially allow arbitrary code execution in the context of the user’s browser. Successful exploitation requires user interaction.

Affected Product(s)

Product Version Build Solution(s)
Symantec Altiris Deployment Solution 6.9.x All Apply Update
Symantec Altiris Notification Server 6.0.x All Apply Update
Symantec Management Platform 7.0.x All Apply Update

Details

Symantec is aware of a vulnerable ActiveX control, AeXNSConsoleUtilities.dll, being reported in Symantec’s Altiris Notification Server / Symantec Management Platform and with Symantec’s Altiris Deployment Solution 6.9. The vulnerable control is downloaded during the initial connection to the web console on the management server to enable authorized admin access to the management server. While the control is not intended to be called externally, it fails to properly validate/filter user input which could potentially allow unauthorized execution of arbitrary code on the targeted system in the context of the user’s browser.
The system the control resides on should not be accessible external to the network in a recommended installation. To attempt to exploit this issue, the system user would need to be enticed to download malicious content either through browsing to a malicious web site, internal or external to the network, or potentially through a malicious html email that could effectively call the vulnerable control.

Mitigations

Symantec Security Response has released IPS/IDS signatures,

23486 - HTTP Altiris Console Utilities AX BO
50239 - MSIE Altiris Console Utilities AX BO

to detect and block attempts to exploit this issue. Signatures will be available through normal update channels.

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
