Directory traversal vulnerability in the web viewers for Business Objects Crystal Reports 9 and 10, and Crystal Enterprise 9 or 10, as used in Visual Studio .NET 2003 and Outlook 2003 with Business Contact Manager, Microsoft Business Solutions CRM 1.2, and other products, allows remote attackers to read and delete arbitrary files via ".." sequences in the dynamicimag argument to crystalimagehandler.aspx.

The web interface for Crystal Reports allows remote attackers to cause a denial of service (disk exhaustion) by repeatedly requesting reports without retrieving the associated image files, which are not cleared from the image file folder.
