Jenkins FitNesse Plugin Password Exposure Vulnerability

Compliance Impact

This vulnerability involves storing passwords unencrypted in job config.xml files on the Jenkins controller, where they can be viewed by users with Extended Read permission or access to the Jenkins controller file system.

Storing passwords in an unencrypted form can lead to unauthorized access to sensitive credentials, which may result in non-compliance with data protection standards and regulations such as GDPR and HIPAA that require protection of sensitive information.

Therefore, this vulnerability could negatively impact compliance with these regulations by exposing sensitive authentication data to unauthorized users.

Detection Guidance

This vulnerability involves passwords being stored unencrypted in job config.xml files on the Jenkins controller.

To detect this vulnerability, you can inspect the config.xml files of Jenkins jobs on the controller for unencrypted passwords.

Since no specific commands or detection tools are provided, a general approach is to search for password fields in the config.xml files.

• Use a command like: grep -r 'password' $JENKINS_HOME/jobs/*/config.xml
• Review the output for any plaintext passwords stored in these files.

Mitigation Strategies

Immediate mitigation steps include restricting access to the Jenkins controller file system and limiting Extended Read permissions to trusted users only.

Additionally, consider upgrading the FitNesse Plugin to a version later than 1.36 where this issue is resolved.

Review and remove any stored plaintext passwords from job config.xml files and replace them with secure credential storage mechanisms.
