Security Advisories Relating to Symantec Products - Symantec’s Altiris Deployment and Notification Management Web Console RunCmd Vulnerability

SYM09-016

November 24, 2009

Revision History

Severity

High

Remote Access Yes

Local Access No

Authentication Required No

Exploit publicly available No

Overview

Symantec’s Altiris Deployment Solution, Notification Server and Symantec Management Platform web consoles install a vulnerable ActiveX control. Exploitation of one of the methods used by this control 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 would require user interaction to download malicious code.

Affected Product(s)

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

Details

Symantec ships an ActiveX control, AeXNSConsoleUtilities.dll with a vulnerable method 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 sufficently validate/filter user input which could potentially allow unauthorized execution of arbitrary code in the context of the user’s browser on a system that has downloaded this control.A successful attempt to exploit this issue would require the system user 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 email that contained HTML or script to call the vulnerable control.

Mitigations

Symantec Security Response has already released IPS signatures,

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

that detect and block attempts to exploit this control. Signatures are 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
