CVE-2022-20613Network attack vector

DNS lookup triggering via forged validation request

Published Jan 12, 2022 · Updated Aug 3, 2024

Cross-site request forgery in Jenkins Mailer Plugin 391.ve4a_38c1b_cf4b_ and earlier allows remote attackers to trigger DNS lookups. The form-validation method accepts non-POST requests and passes an attacker-specified hostname to the controller's DNS resolver. A victim whose browser can reach Jenkins must load the forged request, and the demonstrated consequence is limited to a DNS query from the controller.
