The Fingerprints pages in CloudBees Jenkins before 1.638 and LTS before 1.625.2 might allow remote attackers to obtain sensitive job and build name information via a direct request.

CloudBees Jenkins before 1.638 and LTS before 1.625.2 uses a publicly accessible salt to generate CSRF protection tokens, which makes it easier for remote attackers to bypass the CSRF protection mechanism via a brute force attack.

XML external entity (XXE) vulnerability in the create-job CLI command in CloudBees Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to read arbitrary files via a crafted job configuration that is then used in an “XML-aware tool,” as demonstrated by get-job and update-job.

CloudBees Jenkins before 1.638 and LTS before 1.625.2 do not properly verify the shared secret used in JNLP slave connections, which allows remote attackers to connect as slaves and obtain sensitive information or possibly gain administrative access by leveraging knowledge of the name of a slave.

The sidepanel widgets in the CLI command overview and help pages in CloudBees Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to the pages.

Directory traversal vulnerability in CloudBees Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to list directory contents and read arbitrary files in the Jenkins servlet resources via directory traversal sequences in a request to jnlpJars/.

CloudBees Jenkins before 1.638 and LTS before 1.625.2 do not properly restrict access to API tokens which might allow remote administrators to gain privileges and run scripts by using an API token of another user.

CloudBees Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to queue/api.

CloudBees Jenkins before 1.638 and LTS before 1.625.2 allow attackers to bypass intended slave-to-master access restrictions by leveraging a JNLP slave. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3665.

Cross-site scripting (XSS) vulnerability in the slave overview page in CloudBees Jenkins before 1.638 and LTS before 1.625.2 allows remote authenticated users with certain permissions to inject arbitrary web script or HTML via the slave offline status message.
