Information disclosure via detailed browser errors

Published Sep 14, 2021 · Updated Sep 17, 2024

Information disclosure in IBM Security Verify Privilege Vault before 11.0 allows remote authenticated users to read technical details. The web response returns detailed technical error content to the browser without suppressing sensitive implementation data, but IBM has not disclosed the affected endpoint or handler. A highly privileged account must reach the affected web request; the exposed details can support further attacks against the system.
