Improper Authentication in Jenkins
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.jenkins-ci.main:jenkins-core | >= 2.50, < 2.57 | 2.57 |
| Maven | org.jenkins-ci.main:jenkins-core | < 2.46.2 | 2.46.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance.
