CVE-2019-10337
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 · uneditedAn XML external entities (XXE) vulnerability in Jenkins Token Macro Plugin 2.7 and earlier allowed attackers able to control a the content of the input file for the "XML" macro to have Jenkins resolve external entities, resulting in the extraction of secrets from the Jenkins agent, server-side request forgery, or denial-of-service 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 confidenceThis is an XML External Entity (XXE) vulnerability in Jenkins Token Macro Plugin versions 2.7 and earlier. Attackers who can control the content of an input file passed to the 'XML' macro can inject malicious external entity references, allowing them to extract secrets from the Jenkins agent, perform server-side request forgery (SSRF), or cause denial-of-service conditions.

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 Token Macro Plugin is installedIn Jenkins, go to Manage Jenkins > Manage Plugins > Installed and search for 'Token Macro' to confirm the plugin is present.Affected if The Token Macro plugin is installed
-
Check installed plugin versionIn the plugin management interface, note the version number of the Token Macro plugin and compare it to 2.7 (any version 2.7 or lower is affected).Affected if The installed version is 2.7 or earlier
-
Identify XML macro usageSearch job configurations and pipelines for uses of the 'XML' token macro, particularly where input files or content are passed to it.Affected if The XML macro is used with controllable input files or content
-
Assess input trust levelReview whether input files or content processed by the XML macro come from untrusted sources, user-controlled parameters, or external inputs.Affected if The XML macro processes input from untrusted or user-controlled sources
If the Token Macro plugin version is 2.7 or earlier AND the XML macro processes untrusted input, the environment is affected by this XXE vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 Token Macro Plugin to a version newer than 2.7 to remediate this vulnerability. Additionally, restrict and validate input content for the XML macro to trusted sources only.
