The Sky Software FileView ActiveX control contains unsafe methods, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The Sky Software FileView object is an ActiveX control that is provided with several applications, such as WinZip. This ActiveX control contains several unsafe methods, but is marked "safe for scripting" and "safe for initialization." For example, some of the methods of this ActiveX control allow an attacker to open, copy, delete, or execute arbitrary files on the target computer.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary commands with the privileges of the user. An attacker may also be able to perform other filesystem activities, such as copying or deleting files.
Apply an update
WinZip 10 users should update to WinZip 10 build 7245. This update provides a version of the FileView control that is not marked "safe for scripting" or "safe for initialization," which means that a web page cannot call the unsafe methods. Versions of WinZip prior to 10 do not appear to contain the vulnerable ActiveX control.
This vulnerability was disclosed by TippingPoint ZDI.
