CVE-2022-45400

CVE-2022-45400: XXE vulnerability in Jenkins JAPEX Plugin

JAPEX Plugin 1.7 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control XML input files for the 'Record Japex test report' post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Root Cause Analysis

The vulnerability stems from improper XML parser configuration in the JAPEX Plugin's report processing functionality. While no specific code is provided, the advisory explicitly states the XML parser isn't configured to prevent XXE attacks. In Java XML processing, this typically occurs when DocumentBuilderFactory or SAXParserFactory instances are created without setting security features like FEATURE_SECURE_PROCESSING, XMLConstants.FEATURE_SECURE_PROCESSING, or explicitly disabling DTDs/external entities. The 'Record Japex test report' post-build step's XML parsing routine (likely in a method like parseReport) would be responsible for this insecure configuration. The confidence is high because the vulnerability pattern matches known XXE vulnerabilities in Jenkins plugins where XML parsers are not properly secured.
