Name of the Vulnerable Software and Affected Versions Oracle Business Intelligence Enterprise Edition versions 5.9.0.0.0 through 6.4.0.0.0

Description The issue exists due to insufficient input validation in the Visual Analyzer component. This allows a remote attacker to gain read access to data or modify data via HTTP requests. Successful attacks require human interaction and may significantly impact additional products. Attacks can result in unauthorized update, insert, or delete access to some data, as well as unauthorized read access to a subset of data.

Recommendations For versions 5.9.0.0.0 and 6.4.0.0.0, consider restricting access to the Visual Analyzer component until a patch is available. As a temporary workaround, limit the use of HTTP requests to minimize the risk of exploitation. Avoid using the Visual Analyzer component for sensitive data until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
