Synchronization between the user registry and the IBM BPM database lead to invalid memberships in case there is an internal group in the IBM BPM database and a group in the user registry with the same name.
DESCRIPTION: IBM Business Process Manager is vulnerable to privilege escalation by not properly distinguishing internal group memberships from user registry group memberships. By manipulating LDAP group membership an attack might gain privileged access.
