CVE-2021-30147Public exploitNetwork attack vector

Account creation via unvalidated cross-site POST requests

Published Apr 7, 2021 · Updated Aug 3, 2024

Cross-site request forgery in DMA Softlab Radius Manager 4.4.0 allows remote attackers to create manager accounts via admin.php. The admin.php state-changing endpoints accept cross-site POST requests through an authenticated browser session without verifying request intent. A victim must be logged in with sufficient privileges and visit an attacker-crafted page; a successful request can create accounts or network-service objects under that victim’s authority.
