CVE-2024-39327Network attack vector

Authenticated illegitimate CA signing

Published Feb 18, 2025 · Updated Mar 17, 2025

Improper access control in Atos Eviden IDRA before 2.6.1 allows remote authenticated users to obtain illegitimate CA signing. Eviden has not published the affected component or the authorization decision that incorrectly permits a lower-privileged account to reach CA-signing functionality. Network access with low privileges is required, and successful exploitation enables CA signing outside the account's authorized scope.
