A missing permission check in Jenkins Publish to Bitbucket Plugin 0.4 and earlier allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins.

Affected: Maven: org.jenkins-ci.plugins:publish-to-bitbucket

Jenkins Publish to Bitbucket Plugin 0.4 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.

As of publication of this advisory, there is no fix.

Ein Angreifer kann mehrere Schwachstellen in Jenkins ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen und serverseitige Request-Forgery durchzuführen
