A missing permission check in Jenkins Nexus Task Runner Plugin 0.9.2 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials.

Affected: Maven: org.jenkins-ci.plugins:nexus-task-runner

Jenkins Nexus Task Runner Plugin 0.9.2 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified username and password.

Additionally, this endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) 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
