CVE-2021-29853Network attack vector

Information disclosure via unchecked return values

Published Sep 1, 2021 · Updated Sep 16, 2024

Unchecked return values in IBM Planning Analytics Local 2.0 allow remote authenticated users to obtain attack-enabling information. IBM states that some methods or functions fail to validate their return values, but does not identify the affected locus, exposed data, or triggering request. Network access with low privileges is required, and the documented consequence is limited to information disclosure.
