Remote Access 			Yes
Local Access 			No
Authentication Required 	No
Exploit publicly available 	Metasploit Module available

Symantecs 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 users 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

Symantec is aware of a vulnerable ActiveX control, AeXNSConsoleUtilities.dll, 
being reported in Symantecs Altiris Notification Server / Symantec Management 
Platform and with Symantecs 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 
users 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.

Symantec Response
Symantec engineers have verified this finding and released an update to 
resolve this issue. Symantec is not aware of any customer impact from this 
issue. Follow instructions and hotfix provided below:

For Symantec Altiris Notification Server and Symantec Management Platform, 
Altiris Knowledge Base article 49289, available to customers at 

For Symantec Altiris Deployment Solution, Altiris Knowledge Base article 
49568, available to customers at 

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 
    * Restrict remote access, if required, to trusted/authorized systems 
    * 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 Nikolas Sotiriu, nikolas sotiriu - it services,
