This advisory announces vulnerabilities in the following Jenkins deliverables:
git
Git Plugin 4.11.4 and earlier does not properly mask (i.e., replace with asterisks) credentials in the build log provided by the Git Username and Password (gitUsernamePassword
) credentials binding.
Usernames are masked instead of passwords in cases when usernames are not set to be treated as secret.
Git Plugin 4.11.5 properly masks credentials in the build log provided by the Git Username and Password (gitUsernamePassword
) credentials binding.
As a side effect of the fix, usernames currently set to be not masked will lose their current (unintentional) masking.
jobConfigHistory
Job Configuration History Plugin 1165.v8cc9fd1f4597 and earlier does not escape the job name on the System Configuration History page.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure job names.
Job Configuration History Plugin 1166.vc9f255f45b_8a escapes the job name on the System Configuration History page.
collabnet
CollabNet Plugins Plugin 2.0.8 and earlier stores a RabbitMQ password unencrypted in its global configuration file hudson.plugins.collabnet.share.TeamForgeShare.xml
on the Jenkins controller as part of its configuration.
This password can be viewed by users with access to the Jenkins controller file system.
CollabNet Plugins Plugin 2.0.9 no longer includes the EventQ feature that accepts RabbitMQ credentials. The RabbitMQ password will be removed from the configuration file once it is saved again.
kubernetes-cd
Kubernetes Continuous Deploy Plugin 2.3.1 and earlier bundles a version of Kubernetes Java Client library with the vulnerability CVE-2021-25738 that does not configure its YAML parser to prevent the instantiation of arbitrary types.
This results in a remote code execution (RCE) vulnerability exploitable by users able to provide YAML input files to Kubernetes Continuous Deploy Plugin’s build step.
