Title: Microsoft IE4 Clipboard Paste Vulnerability
Severity: MODERATE
Description:
The Windows clipboard contains data that has been cut or copied from various windows applications. This data can be accessed and posted to malicious web forms at web sites without the knowledge of the visiting end-user. Normally, Microsoft security prevents forms from accessing data other than what was copied from within the same application, however, a Microsoft Forms 2.0 TextBox ActiveX object can bypass these security rules.
The Forms 2.0 ActiveX object does not come with the Operating System. This control is loaded when Visual Basic 5.0, Project 98, Outlook 98, or Office 97 is installed on the host.
Affected Products:
- Microsoft Internet Explorer 4.0
- Microsoft Internet Explorer 4.0 for Windows 95
- Microsoft Internet Explorer 4.0 for Windows NT 4.0
- Microsoft Office 97
- Microsoft Outlook 98
- Microsoft Project 98
- Microsoft Visual Basic 5.0
- Microsoft Windows 95
- Microsoft Windows 98
- Microsoft Windows NT 4.0
