Description
Jenkins XebiaLabs XL Deploy Plugin 10.0.1 and earlier does not perform a permission check in a method implementing form validation. This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability. An enumeration of credentials IDs in XebiaLabs XL Deploy Plugin 10.0.2 requires the appropriate permissions.
