Apache CXF JMS configuration RCE via RMI/LDAP URLs

IdentifiersCVE-2025-48913CWE-94

CVE-2025-48913 is a vulnerability in Apache CXF's JMS configuration handling. When untrusted users are permitted to configure JMS, affected versions allowed the use of RMI or LDAP URLs in that configuration. Those protocols could be leveraged to trigger code execution, making the issue effectively a remote code execution risk arising from unsafe acceptance of attacker-controlled naming or lookup endpoints in JMS-related configuration. Reported affected versions are Apache CXF 4.1.0 before 4.1.3, 4.0.0 before 4.0.9, and 3.6.x before 3.6.8. Apache addressed the issue by restricting the interface to reject RMI and LDAP protocols in this context.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can provide an attacker with code execution capabilities in the context of the Apache CXF application or service using the vulnerable JMS transport/configuration path. The practical impact depends on the privileges of the running process and surrounding deployment, but may include full compromise of the affected service, execution of arbitrary attacker-controlled code, follow-on access to application data, and potential lateral movement from the compromised host.

Mitigation

If you can’t patch tonight, do this now.

Do not allow untrusted or low-trust users to configure JMS settings in Apache CXF. Restrict administrative access to JMS configuration, validate and tightly control configuration inputs, and prohibit use of RMI- or LDAP-based URLs in JMS-related configuration until patched. Where possible, limit outbound connectivity to untrusted naming or directory services to reduce exploitability.

Remediation

Patch, then assume compromise.

Upgrade Apache CXF to a fixed release: 3.6.8, 4.0.9, 4.1.3, or later as appropriate for the deployed branch. The fix restricts the relevant interface so that RMI and LDAP protocols are rejected in JMS configuration, removing the known code-execution path.
