CVE-2026-44417: CWE-20 Improper Input Validation in Apache Software Foundation Apache CXF
The fix for CVE-2025-48913: Apache CXF: Untrusted JMS configuration can lead to RCE was not complete, meaning that another path in the code might lead to code execution capabilities, if untrusted users are allowed to configure JMS for Apache CXF. Users are recommended to upgrade to versions 4.2.1, 4.1.6 or 3.6.11, which fix this issue.
AI Analysis
Technical Summary
This vulnerability in Apache CXF arises from incomplete remediation of a prior JMS configuration-related remote code execution flaw (CVE-2025-48913). Improper input validation (CWE-20) allows an attacker with limited privileges to potentially execute arbitrary code if they can supply untrusted JMS configuration data. The vulnerability affects Apache CXF versions 4.2.0 and 4.0.0. The vendor advisory from Red Hat confirms the issue and recommends upgrading to fixed versions 4.2.1, 4.1.6, or 3.6.11. The CVSS v3.1 base score is 7.5, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, and requiring low privileges but high attack complexity.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code remotely via untrusted JMS configuration inputs. This could lead to full compromise of the affected Apache CXF service, impacting confidentiality, integrity, and availability of the system. The vulnerability requires that untrusted users have the ability to configure JMS, which may limit exposure depending on deployment context.
Mitigation Recommendations
A fix is available. Users should upgrade Apache CXF to versions 4.2.1, 4.1.6, or 3.6.11 as recommended by the vendor advisory. No alternative mitigations or workarounds are specified. Patch status is confirmed by the vendor advisory. Applying the update will remediate the vulnerability.
