Incorrect Permission Assignment for Critical Resource in Jenkins Mailer Plugin
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.jenkins-ci.plugins:mailer | >= 391.ve4a38c1bcf4b, < 408.vd726a | 408.vd726a |
| Maven | org.jenkins-ci.plugins:mailer | < 1.34.2 | 1.34.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
Jenkins Mailer Plugin prior to 408.vd726a_1130320 and 1.34.2 does not perform a permission check in a method implementing form validation.
This allows attackers with Overall/Read access to use the DNS used by the Jenkins instance to resolve an attacker-specified hostname.
Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Mailer Plugin 408.vd726a_1130320 and 1.34.2 requires POST requests and Overall/Administer permission for the affected form validation method.
