CVE-2020-2234
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 · uneditedA missing permission check in Jenkins Pipeline Maven Integration Plugin 3.8.2 and earlier allows users with Overall/Read access to connect to an attacker-specified JDBC URL using attacker-specified credentials IDs obtained through another method, potentially capturing credentials stored in Jenkins.
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 Pipeline Maven Integration Plugin versions 3.8.2 and earlier lack a permission check on a functionality that allows JDBC URL connections. Users with only Overall/Read access (the minimum privilege level) can exploit this to connect to attacker-specified JDBC URLs using credential IDs, potentially exfiltrating stored Jenkins credentials.

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 if Pipeline Maven Integration Plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed tab, or check the file $JENKINS_HOME/plugins/pipeline-maven/ for presenceAffected if Plugin is not installed - not affected
-
Check the installed version of Pipeline Maven Integration PluginIn Jenkins UI: Manage Jenkins > Manage Plugins > Installed tab, find Pipeline Maven Integration and note the version. Alternatively, check the file $JENKINS_HOME/plugins/pipeline-maven/META-INF/MANIFEST.MF for the Plugin-VersionAffected if Version is 3.8.2 or earlier - affected
-
Identify users with Overall/Read permissionNavigate to Manage Jenkins > Manage Users, or inspect $JENKINS_HOME/users/ directory. In Jenkins UI: Manage Jenkins > Configure Global Security to review authorization settingsAffected if Users with Overall/Read access exist - potentially affected if plugin version is vulnerable
-
Verify if database configuration features are accessibleLook for Maven > Configure Maven triggers or similar configuration pages that allow JDBC URL configuration in the Jenkins UIAffected if JDBC URL configuration functionality is available to low-privilege users - likely affected
-
Check for JDBC-related credentials in JenkinsNavigate to Manage Jenkins > Manage Credentials, or check $JENKINS_HOME/credentials.xmlAffected if JDBC credentials exist - affected if vulnerable plugin version allows access to them
If the Pipeline Maven Integration Plugin version is 3.8.2 or earlier and users with Overall/Read permission can access JDBC configuration features, the environment is affected by this vulnerability.

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 dataUpdate the Jenkins Pipeline Maven Integration Plugin to a version newer than 3.8.2. Additionally, review and restrict user permissions to the minimum required for their roles.
