CVE-2023-47577Network attack vector

Unauthorized password changes via missing current-password validation

Published Dec 13, 2023 · Updated Aug 2, 2024

Improper authentication in Relyum RELY-PCIe 22.2.1 and RELY-REC 23.1.0 allows remote attackers to change account passwords. The password-change operation accepts a replacement password without first validating the account's current password. Network access is the only published gate, and the documented consequence is unauthorized replacement of an account password.
