1) Improper access control (CVE-ID: CVE-2022-43782)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

Remediation

Install update from vendor's website.
