The eBay Enhanced Picture Uploader ActiveX control allows arbitrary commands to be executed.
The eBay Enhanced Picture Uploader ActiveX control is used by the eBay web site to give Internet Explorer users additional functionality when uploading pictures to an auction. This ActiveX control is provided by the file EPUWALcontrol.dll
. If an attacker provides a specially-crafted PictureUrls
property or initialization parameter, the ActiveX control will execute the commands that are specified.
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.

This update is addressed in version 1.0.27 of the Ebay Enhanced Picture Control software. This update can be obtained by visiting the eBay web site, creating a new auction and uploading images with the Internet Explorer web browser. This control is also disabled in Internet Explorer with the update for Microsoft Security Advisory (969898). Please see the eBay security center announcement for additional details.
