HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Jenkins Ansible Plugin 204.v8191fd551eb_f and earlier does not mask extra variables displayed on the configuration form, increasing the potential for attackers to observe and capture them.

Jenkins Ansible Plugin 204.v8191fd551eb_f and earlier stores extra variables unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

Missing permission checks in Jenkins Ansible Plugin 1.0 and earlier allow attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins.

A missing permission check in Jenkins Ansible Tower Plugin 0.9.1 and earlier in the TowerInstallation.TowerInstallationDescriptor#doFillTowerCredentialsIdItems method allowed attackers with Overall/Read permission to enumerate credentials ID of credentials stored in Jenkins.

A missing permission check in Jenkins Ansible Tower Plugin 0.9.1 and earlier in the TowerInstallation.TowerInstallationDescriptor#doTestTowerConnection form validation method allowed attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

ansible-tower: cross-site request forgery could result in credentials disclosure

A cross-site request forgery vulnerability in Jenkins Ansible Tower Plugin 0.9.1 and earlier in the TowerInstallation.TowerInstallationDescriptor#doTestTowerConnection form validation method allowed attackers permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins

A man in the middle vulnerability exists in Jenkins Ansible Plugin 0.8 and older in AbstractAnsibleInvocation.java, AnsibleAdHocCommandBuilder.java, AnsibleAdHocCommandInvocationTest.java, AnsibleContext.java, AnsibleJobDslExtension.java, AnsiblePlaybookBuilder.java, AnsiblePlaybookStep.java that disables host key verification by default.
