Vulnerability Information

Severity: High
Vulnerability Published: 2012-03-28
Patch Published: N/A
CVE [?]: CVE-2012-4876
CPE [?]: cpe:/a:trendnet:securview_wireless_internet_camera_activex_control

Synopsis

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

Description

The remote host has the TRENDnet SecurView UltraMJCam ActiveX control installed. A stack-based buffer overflow can be triggered by providing an overlong argument to the 'OpenFileDlg()' method. This is because the method does not verify the size of the argument before calling 'WideCharToMultiByte()'.

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.

Solution

Remove or disable the control as fixes are not available.
