CVE-2024-27269Network attack vector

Cross-tenant disclosure via incorrect user management

Published May 10, 2024 · Updated Aug 2, 2024

Incorrect user management in IBM QRadar SIEM 7.5 allows remote authenticated users with high privileges to read sensitive cross-tenant data. The affected user-management configuration exposes information belonging to unintended tenants, but IBM has not disclosed the specific setting, request path, or authorization check that fails. Exploitation requires a privileged account and affects confidentiality across tenant boundaries, with no reported ability to modify data or interrupt service.
