Overview
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
Details
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.

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
