HTTP CA BrightStor ActiveX BO

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempt to exploit a buffer overflow vulnerability by passing long arguments into a method of CA BrightStor ListCtrl.ocx ActiveX Control.

Additional Information

The Unicenter DSM r11 List Control ATX ActiveX control, included with CA BrightStor ARCserve Backup, is prone to a buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit this issue to execute arbitrary code in the context of an application running the control (typically Internet Explorer). Failed attacks will cause denial-of-service conditions.


  • Unicenter DSM r11 List Control ATX on CA BrightStor ARCserve Backup r11.5 is vulnerable; other versions may also be affected.
