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 · unedited
Jenkins Amazon EC2 Plugin 1.43 and earlier wrote the beginning of private keys to the Jenkins system log.

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 confidence

The Jenkins Amazon EC2 Plugin versions 1.43 and earlier had a logging flaw where the beginning portion of SSH private keys was being written to the Jenkins system log. This exposed sensitive credential material through logs that may be accessible to unauthorized users, representing an information disclosure vulnerability.

MitigationUpgrade the Amazon EC2 Plugin to version 1.44 or later to remediate the private key logging issue. Review historical Jenkins system logs for any potential exposure of private key material.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Amazon EC2 Plugin is installed
    Navigate to Jenkins Manage Plugins > Installed and look for 'Amazon EC2' plugin in the list. Note the installed version number shown.
    Affected if Plugin version 1.43 or earlier is listed
  2. Verify EC2 cloud configuration exists
    Go to Jenkins > Manage Jenkins > Configure Clouds (or EC2 configuration page). Check if any EC2 cloud entries are configured with SSH private key credentials.
    Affected if EC2 cloud is configured and using SSH key authentication
  3. Search logs for private key material
    Locate the Jenkins system log files (typically found in $JENKINS_HOME/logs or the journal/logs directory). Search for patterns matching the beginning of SSH private keys, such as '-----BEGIN RSA PRIVATE KEY-----' or similar PEM header strings.
    Affected if Log files contain any SSH private key material or PEM-formatted credential headers
  4. Review historical logs if current version is patched
    If the plugin has been upgraded to version 1.44 or later, review archived or historical log files that existed before the upgrade for any exposed private key content.
    Affected if Historical logs contain private key material from before patching

The environment is affected if the Amazon EC2 Plugin version is 1.43 or earlier and EC2 clouds were configured with SSH private key credentials, as the private key material may have been written to system logs.
