CVE-2023-51518

CRITICAL 9.8EPSS 1.2%

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
