Dell Webcam CrazyTalk ActiveX Remote Overflow

High Nessus Plugin ID 58483


The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.


The remote Windows host contains an install of the CrazyTalk ActiveX control, bundled with Dell Webcam software, that reportedly fails to sanitize input to the 'BackImage', 'ScriptName', 'ModelName', and 'SRC' properties, which could be abused to trigger a buffer overflow.

By tricking a user into opening a specially crafted web page, a remote, unauthenticated attacker could execute arbitrary code on the remote host subject to the user's privileges.


Remove or disable the control as fixes are not available.
