CVE-2023-37952Network attack vector

Credential capture via CSRF-triggered endpoint requests

Published Jul 12, 2023 · Updated Nov 7, 2024

Cross-site request forgery in Jenkins mabl Plugin 0.0.46 and earlier allows remote attackers to capture stored Jenkins credentials. MablStepBuilder form-validation and application and environment list endpoints accept GET requests, attacker-supplied service URLs, and a credential ID, then send the selected secret in an outbound request. Exploitation requires a logged-in Jenkins user to visit attacker-controlled content; the captured secret can then be used outside Jenkins.
