CVE-2021-20583Network attack vector

Sensitive-data disclosure via unvalidated HTTP GET request

Published Jun 25, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Security Verify Privilege Vault before 10.9.66 allows remote authenticated users to read sensitive data. An HTTP GET request reaches an input-validation flaw, but IBM has not disclosed the affected endpoint, parameter, or validation error. Exploitation requires a highly privileged user and user interaction; the reported consequence is limited to confidentiality.
