CVE-2020-4503Network attack vector

Credential disclosure via unsanitized Web UI JavaScript

Published Jun 2, 2020 · Updated Sep 16, 2024

Cross-site scripting in IBM Planning Analytics Local 2.0 allows remote attackers to run JavaScript in the Web UI and expose credentials. The Web UI accepts user-embedded script without adequate neutralization, allowing script execution in a trusted session. A victim must interact with the affected interface, and the documented consequence is credential disclosure and altered functionality rather than service interruption.
