Description
CF UAA versions prior to 74.1.0, allow external input to be directly queried against. A remote malicious user with 'client.write' and 'groups.update' can craft a SCIM query, which leaks information that allows an escalation of privileges, ultimately allowing the malicious user to gain control of UAA scopes they should not have.
