Used Microsoft Windows NT 4.0 Patch: Malformed Hit-highlighting for Windows? Share your experience and help other users.
Developer’s Description
When you conduct a search using Indexing Server 2.0, the hit-highlighting function provides search results that highlight portions of documents that satisfy your search query. This vulnerability exists because Indexing Server 2.0 doesn't set the correct parameters for hit-highlighting search requests. If a malicious user provides a specific type of malformed request, it retrieves files on the server, regardless of the permissions that have been set by the administrator.
By design, the hit-highlighting feature allows the user to specify the name of the document to be hit-highlighted. The user should only be able to request documents within the server's virtual directories; however, if a specific type of malformed argument is provided, it can be used to request a file by its physical location on the drive.
