Summary

The Apache James Server versions up to 3.7.3 expose a JMX management service that lacks authentication by default, creating a potential risk for privilege escalation by malicious local users. To mitigate this risk, administrators are strongly advised to disable the JMX service or implement a password for JMX access. Notably, starting from version 3.7.4, a JMX password is automatically configured for Guice users, enhancing security against unauthorized access.

Affected Version(s)

Apache James server 0 <= 3.7.3

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
