rgod has discovered a weakness in ImageShack Toolbar, which can be exploited by malicious people to potentially disclose sensitive information.
The weakness is caused due to the ImageShackToolbar.FileUploader.1 ActiveX control (ImageShackToolbar.dll) including the insecure "BuildSlideShow()" method. This can be exploited to upload a specific image on a user's system to the ImageShack site or disclose contents of non-image files by using e.g. a network sniffer on a local network.
Successful exploitation requires knowledge of the full path and filename of the target file.
The weakness is confirmed in ImageShackToolbar.dll version 184.108.40.206. Other versions may also be affected.
Solution: Set the kill-bit for the affected ActiveX control.
