| |
| <h2 id="description">Description</h2> |
| |
| <p>If the broker is configured with different authentication providers on |
| different ports one of which is an HTTP port, then the broker can be |
| tricked by a remote unauthenticated attacker connecting to the HTTP |
| port into using an authentication provider that was configured on a |
| different port. The attacker still needs valid credentials with the |
| authentication provider on the spoofed port. This becomes an issue |
| when the spoofed port has weaker authentication protection (e.g., |
| anonymous access, default accounts) and is normally protected by |
| firewall rules or similar which can be circumvented by this |
| vulnerability. AMQP ports are not affected. Versions 6.0.0 and newer |
| are not affected.</p> |
| |
| <h2 id="resolution">Resolution</h2> |
| |
| <p>Users of affected versions who have more than one port and different |
| authentication providers configured on them should upgrade to a |
| later unaffected version (recommended).</p> |
| |
| <h2 id="mitigation">Mitigation</h2> |
| |
| <p>If upgrading the broker is not possible then users should ensure all |
| their authentication providers offer an equal amount of protection. |
| In particular, authentication providers with default accounts and |
| those with anonymous access should be removed if other providers in |
| use require credentials.</p> |
