CVE-2020-20989Public exploitNetwork attack vector

Log deletion via missing CSRF validation

Published Aug 12, 2021 · Updated Aug 4, 2024

Cross-site request forgery in DomainMOD 4.13 allows remote attackers to delete application logs through an administrator's browser. The /admin/maintenance/ handler performs a log-deletion operation from a state-changing request without validating an anti-CSRF token. An authenticated administrator must be induced to submit the crafted request, and successful exploitation removes audit data rather than altering managed domains.
