Detailed vulnerability description
The vulnerability allows a remote attacker to gain unauthorized access to other servers.
The vulnerability exists due to use of a hard-coded cryptographic key in the remember-me token configuration in etc/security/mh_default_org.xml when validating remember-me authentication tokens. A remote attacker can reuse a compromised remember-me token from one server to gain unauthorized access to other servers.
The issue is particularly relevant in clustered deployments where multiple machines accept the same credentials.
