CVE-2023-51518

Apache James server: Privilege escalation via JMX pre-authentication deserialisation

State: Published
Severity: 9.8 Critical
Published: Feb 27, 2024
Updated: Aug 22, 2024
Reserved: Dec 20, 2023

Description

Apache James prior to version 3.7.5 and 3.8.0 exposes a JMX endpoint on localhost subject to pre-authentication deserialisation of untrusted data. Given a deserialisation gadjet, this could be leveraged as part of an exploit chain that could result in privilege escalation. Note that by default JMX endpoint is only bound locally.

We recommend users to: - Upgrade to a non-vulnerable Apache James version

- Run Apache James isolated from other processes (docker - dedicated virtual machine) - If possible turn off JMX
