CVE-2023-24441
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 MSTest Plugin 1.0.0 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 MSTest Plugin 1.0.0 and earlier contains an XML External Entity (XXE) vulnerability because its XML parser is not configured to prevent external entity processing. This allows attackers to inject malicious XML containing external entity references to potentially read local files on the Jenkins controller/agent, perform SSRF attacks, or cause denial of service.

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 MSTest plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab and search for 'MSTest' or check the plugin directory $JENKINS_HOME/plugins/ for a mstest folderAffected if The MSTest plugin appears in the installed plugins list
-
Determine MSTest plugin versionIn Jenkins > Manage Jenkins > Manage Plugins > Installed, click on the MSTest plugin to view its version, or inspect the plugin's MANIFEST.MF file in $JENKINS_HOME/plugins/mstest/Affected if The installed version is 1.0.0 or any version earlier than 1.0.0
-
Identify jobs using MSTest functionalitySearch Jenkins job configurations for MSTest-related build steps such as 'Publish MSTest results' or similar MSTest execution commandsAffected if Jobs are configured to publish or process MSTest results via the plugin
-
Confirm XML result processing is enabledReview the affected jobs and verify that they accept and process MSTest XML result files (typically .trx files) as part of the buildAffected if Jobs are configured to parse MSTest XML output files through the plugin
You are affected if the MSTest plugin is installed at version 1.0.0 or earlier AND jobs are configured to use the plugin to process MSTest XML results.
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 to a patched version of the Jenkins MSTest Plugin once available, or disable the plugin if not needed. If an immediate patch is unavailable, consider input validation or restricting plugin permissions as a temporary measure.
