Jenkins Enterprise by CloudBees 1.565.1.1 up to 1.565.2.x, 1.554.1.1 up to 1.554.9.x, and 1.532.1.1 up to 1.532.9.x
SECURITY-87/CVE-2014-3661 (anonymous DoS attack through CLI handshake)
This vulnerability allows unauthenticated users with access to Jenkins' HTTP/HTTPS port to mount a DoS attack on Jenkins through thread exhaustion.
SECURITY-110/CVE-2014-3662 (User name discovery)
Anonymous users can test if the user of a specific name exists or not through login attempts.
SECURITY-127&128/CVE-2014-3663 (privilege escalation in job configuration permission)
An user with a permission limited to Job/CONFIGURE can exploit this vulnerability to effectively create a new job, which should have been only possible for users with Job/CREATE permission, or to destroy jobs that he/she does not have access otherwise.
SECURITY-131/CVE-2014-3664 (directory traversal attack)
Users with Overall/READ permission can access arbitrary files in the file system readable by the Jenkins process, resulting in the exposure of sensitive information, such as encryption keys.
SECURITY-138/CVE-2014-3680 (Password exposure in DOM)
If a parameterized job has a default value in a password field, that default value gets exposed to users with Job/READ permission.
SECURITY-143/CVE-2014-3681 (XSS vulnerability in Jenkins core)
Reflected cross-site scripting vulnerability in Jenkins core. An attacker can navigate the user to a carefully crafted URL and have the user execute unintended actions.
SECURITY-150/CVE-2014-3666 (remote code execution from CLI)
Unauthenticated user can execute arbitrary code on Jenkins master by sending carefully crafted packets over the CLI channel.
SECURITY-155/CVE-2014-3667 (exposure of plugin code)
Programs that constitute plugins can be downloaded by anyone with the Overall/READ permission, resulting in the exposure of otherwise sensitive information, such as hard-coded keys in plugins, if any.
SECURITY-159/CVE-2013-2186 (arbitrary file system write)
Security vulnerability in commons fileupload allows unauthenticated attacker to upload arbitrary files to Jenkins master.
SECURITY-113/CVE-2014-3678 (XSS vulnerabilities in monitoring plugin)
Monitoring plugin allows an attacker to cause a victim into executing unwanted actions on Jenkins instance.
SECURITY-113/CVE-2014-3679 (hole in access control)
Certain pages in monitoring plugin are visible to anonymous users, allowing them to gain information that they are not supposed to.
