CVE-2023-37957Public exploitNetwork attack vector

Account impersonation via unprotected token-generation endpoint

Published Jul 12, 2023 · Updated Nov 6, 2024

Cross-site request forgery in Jenkins Project Pipeline REST API Plugin 0.11 and earlier allows remote attackers to steal a victim's JCLI token. The InstanceAPI#doGenerateToken endpoint accepts a GET request, creates a token for the signed-in user, and POSTs it to an untrusted callback URL. Exploitation requires an authenticated victim to visit a crafted link; the stolen token permits account impersonation with the victim's Jenkins privileges.
