CVE-2025-20628
Insufficient granularity of access control for Remote Connector Servers in client mode
Description
An insufficient granularity of access control vulnerability exists in PingIDM (formerly ForgeRock Identity Management) where administrators cannot properly configure access rules for Remote Connector Servers (RCS) running in client mode. This means attackers can spoof a client-mode RCS (if one exists) to intercept and/or modify an identity’s security-relevant properties, such as passwords and account recovery information. This issue is exploitable only when an RCS is configured to run in client mode.
