Description
This security bulletin contains information about 1 security vulnerability.
1) Improper access control (CVE-ID: CVE-2022-43782)
The vulnerability allows a remote attacker to compromise the affected application.
The vulnerability exists due to a security misconfiguration. A remote attacker connecting from IP in the allow list to authenticate as the crowd application through bypassing a password check can access privileged endpoints in Crowd's REST API under the usermanagement path and compromise the affected application.
The vulnerability exists only under the following conditions:
- the vulnerability concerns only new installations of affected versions: if you upgraded from an earlier version, for example version 2.9.1, to version 3.0.0 or later, your instance is not affected.
- an IP address has been added to the Remote Address configuration of the crowd application (which is none by default in versions after 3.0.0)
