The remote host has the D-Link DCS-5605 Network Surveillance DcsCliCtrl.dll ActiveX control installed. This control fails to properly parse data supplied to the ‘SelectDirectory()’ function due to an unsafe call to ‘lstrcpyW()’, which can lead to a stack 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.
