Name of the Vulnerable Software and Affected Versions Microstrategy Web version 7

Description A directory traversal issue exists, allowing remote authenticated users to bypass SecurityManager restrictions. This is achieved by providing a /.. (slash dot dot) in a pathname used by the web application, specifically in the subpage parameter of the "/WebMstr7/servlet/mstrWeb" endpoint.

Recommendations For Microstrategy Web version 7, as a temporary workaround, consider restricting access to the "/WebMstr7/servlet/mstrWeb" endpoint until a fix is available. Avoid using the subpage parameter in this endpoint to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
