CVE-2018-1999031
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 exposure of sensitive information vulnerability exists in Jenkins meliora-testlab Plugin 1.14 and earlier in TestlabNotifier.java that allows attackers with file system access to the Jenkins master to obtain the API key stored in this plugin's configuration.
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 meliora-testlab Jenkins plugin versions 1.14 and earlier stores the Testlab API key in plaintext within its configuration file (TestlabNotifier.java). An attacker with file system access to the Jenkins master can read this configuration file and obtain the API key, potentially allowing unauthorized access to the Testlab 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.
-
Identify if meliora-testlab plugin is installedNavigate to Jenkins Manage Plugins > Installed tab, or inspect the plugins directory on the Jenkins master file system for a meliora-testlab folderAffected if The plugin folder exists in the Jenkins plugins directory
-
Determine the installed plugin versionCheck the plugin's manifest file (typically MANIFEST.MF or the .jpi file's metadata) for the version number, or view the version in the Jenkins plugin manager UIAffected if The version is 1.14 or lower
-
Locate the Testlab notifier configurationSearch in the Jenkins home directory for files containing 'testlab' or 'TestlabNotifier' in the name, typically found under $JENKINS_HOME/org.jenkinsci.plugins meliora-testlab/ or within the main Jenkins configuration XML filesAffected if A Testlab notifier configuration file exists
-
Inspect configuration for plaintext API keyOpen the Testlab configuration file and search for any field labeled 'apiKey', 'api.token', or similar credential field. Check if the value appears as a raw alphanumeric string rather than a Jenkins credential ID reference (such as $CREDENTIALS_ID)Affected if The API key or token appears as a visible plaintext string value in the configuration
The environment is affected if the meliora-testlab plugin version is 1.14 or lower and a Testlab notifier configuration contains a plaintext API key rather than a credential ID reference.

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 meliora-testlab plugin to a version newer than 1.14 (which should implement secure credential storage), and rotate any API keys that may have been exposed.
