This advisory announces vulnerabilities in the following Jenkins deliverables:
Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint.
This allows attackers with Computer/Create permission but without Computer/Extended Read permission to copy an agent, gaining access to its configuration.
Jenkins 2.504, LTS 2.492.3 requires Computer/Extended Read permission to copy an agent.
Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint.
This allows attackers with Computer/Create permission but without Computer/Configure permission to copy an agent, gaining access to encrypted secrets in its configuration.
| This is due to an incomplete fix of SECURITY-3495. |
Jenkins 2.504, LTS 2.492.3 requires Computer/Configure permission to copy an agent containing secrets.
templating-engine
Templating Engine Plugin allows defining libraries both in the global configuration, as well as scoped to folders containing the pipelines using them. While libraries in the global configuration can only be set up by administrators and can therefore be trusted, libraries defined in folders can be configured by users with Item/Configure permission.
In Templating Engine Plugin 2.5.3 and earlier, libraries defined in folders are not subject to sandbox protection. This vulnerability allows attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.
In Templating Engine Plugin 2.5.4, libraries defined in folders are subject to sandbox protection.
simple-queue
Simple Queue Plugin 1.4.6 and earlier does not require POST requests for multiple HTTP endpoints, resulting in cross-site request forgery (CSRF) vulnerabilities.
These vulnerabilities allow attackers to change and reset the build queue order.
Simple Queue Plugin 1.4.7 requires POST requests for the affected HTTP endpoints.
| Administrators can enable equivalent HTTP endpoints without CSRF protection via the global configuration. |
vmanager-plugin
Cadence vManager Plugin 4.0.0-282.v5096a_c2db_275 and earlier stores Verisium Manager vAPI keys unencrypted in job config.xml files on the Jenkins controller as part of its configuration.
These API keys can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
Cadence vManager Plugin 4.0.1-286.v9e25a_740b_a_48 stores Verisium Manager vAPI keys encrypted once affected job configurations are saved again.
monitor-remote-job
monitor-remote-job Plugin 1.0 stores passwords unencrypted in job config.xml files on the Jenkins controller as part of its configuration.
These passwords can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
As of publication of this advisory, there is no fix. Learn why we announce this.
stackhammer
Stack Hammer Plugin 1.0.6 and earlier stores Stack Hammer API keys unencrypted in job config.xml files on the Jenkins controller as part of its configuration.
These API keys can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
As of publication of this advisory, there is no fix. Learn why we announce this.
asakusa-satellite-plugin
AsakusaSatellite Plugin 0.1.1 and earlier stores AsakusaSatellite API keys unencrypted in job config.xml files on the Jenkins controller as part of its configuration.
These API keys can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
Additionally, the job configuration form does not mask these API keys, increasing the potential for attackers to observe and capture them.
As of publication of this advisory, there is no fix. Learn why we announce this.
