CVE-2020-4366Network attack vector

Credential disclosure via Web UI script injection

Published Jun 2, 2020 · Updated Sep 16, 2024

Cross-site scripting in IBM Planning Analytics Local 2.0 allows remote attackers to disclose credentials through its Web UI. IBM states that the Web UI accepts embedded arbitrary JavaScript, but it has not disclosed the affected request, field, or output-encoding failure. Execution requires user interaction with attacker-controlled content in a trusted session, where the script can alter displayed behavior and expose credentials.
