This advisory announces vulnerabilities in the following Jenkins deliverables:
docker-plugin
Docker Plugin did not perform permission checks on a method implementing form validation. This allowed users with Overall/Read access to Jenkins to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
Additionally, this form validation method did not require POST requests, resulting in a cross-site request forgery vulnerability.
This form validation method now requires POST requests and Overall/Administer or Item/Configure permission, as appropriate.
docker-plugin
Docker Plugin provides a list of applicable credential IDs to allow users configuring the plugin to select the one to use.
This functionality did not correctly check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those could be used as part of an attack to capture the credentials using another vulnerability.
An enumeration of credentials IDs in this plugin now requires the appropriate permission, typically Overall/Administer or Item/Configure.
embeddable-build-status
Embeddable Build Status Plugin did not sanitize arguments provided in the query string, resulting in a reflected cross-site scripting vulnerability.
Arguments are now sanitized.
mashup-portlets-plugin
Mashup Portlets Plugin stored SonarQube credentials unencrypted on the Jenkins controller. These credentials could be viewed by users with access to the Jenkins controller file system.
Mashup Portlets Plugin now stores these credentials encrypted.
gogs-webhook
Gogs Plugin stored credentials unencrypted in job config.xml files on the Jenkins controller.
These credentials could be viewed by users with Extended Read permission, or access to the Jenkins controller file system.
Gogs Plugin now stores credentials encrypted.
depgraph-view
Dependency Graph Viewer Plugin does not correctly escape the Display Name value for jobs in Jenkins, resulting in a stored cross-site scripting vulnerability.
As of publication of this advisory, there is no fix.
port-allocator
Port Allocator Plugin stores credentials unencrypted in job config.xml files on the Jenkins controller.
These credentials can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.
As of publication of this advisory, there is no fix.
caliper-ci
Caliper CI Plugin stores credentials unencrypted in job config.xml files on the Jenkins controller.
These credentials can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.
As of publication of this advisory, there is no fix.
These versions include fixes to the vulnerabilities described above. All prior versions are considered to be affected by these vulnerabilities unless otherwise indicated.
As of publication of this advisory, no fixes are available for the following plugins:
