CVE-2022-25209
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedJenkins Chef Sinatra Plugin 1.20 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Jenkins Chef Sinatra Plugin versions 1.20 and earlier contains an XML external entity (XXE) vulnerability because its XML parser is not configured to disable external entity processing. This allows attackers to inject malicious XML containing external entity references to read local files or perform server-side request forgery (SSRF).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Chef Sinatra Plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed tab, or use Jenkins CLI: java -jar jenkins-cli.jar list-plugins | grep -i 'chef-sinatra'Affected if The plugin appears in the list of installed plugins
-
Determine installed plugin versionIn Jenkins UI, click on the Chef Sinatra Plugin in the Installed tab to view version details. Alternatively, check the plugin manifest file: $JENKINS_HOME/plugins/chef-sinatra-plugin/META-INF/MANIFEST.MFAffected if Plugin version is 1.20 or earlier
-
Confirm plugin XML processing is in useReview Jenkins job configurations or system configurations that may invoke the Chef Sinatra Plugin to process XML data. Check job configuration XML files in $JENKINS_HOME/jobs/Affected if The plugin is configured to process XML input from untrusted sources
-
Check XML parser configurationInspect the plugin source code or decompiled classes for XMLParser configuration. Look for DocumentBuilderFactory or XMLStreamReader instantiation without disallowing external entities.Affected if The plugin code does not set XMLConstants.ACCESS_EXTERNAL_DTD or XMLConstants.ACCESS_EXTERNAL_SCHEMA properties to empty strings
You are affected if the Chef Sinatra Plugin version is 1.20 or earlier and the plugin processes XML input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade the Jenkins Chef Sinatra Plugin to version 1.21 or later, which configures the XML parser to prevent XXE attacks by disabling external entity processing.
