| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Jenkins JX Resources Plugin versions 1.0.36 and earlier
Description
A missing permission check in the GlobalPluginConfiguration#doValidateClient method allowed users with Overall/Read access to connect to an attacker-specified Kubernetes server, potentially leaking credentials. This issue also allowed attackers to obtain information about an attacker-specified namespace and the value of any attacker-specified environment variable for the Jenkins controller process. Furthermore, it resulted in a cross-site request forgery vulnerability due to not requiring POST requests.
Recommendations
For Jenkins JX Resources Plugin versions 1.0.36 and earlier, update the plugin to a version that requires POST requests and Overall/Administer permissions for the form validation method, or apply a configuration change to restrict access to the GlobalPluginConfiguration#doValidateClient method to users with Overall/Administer permissions. As a temporary workaround, consider restricting the
GlobalPluginConfiguration#doValidateClient method to require Overall/Administer permissions until a patch is available.Fix
