CVE-2021-32402Network attack vector

Unauthorized actions via unvalidated cross-site requests

Published May 17, 2021 · Updated Aug 3, 2024

Cross-site request forgery in Intelbras Router RF 301K firmware 1.1.2 allows remote attackers to perform unspecified actions. The web-management inputs and modules accept forged requests without adequate validation, but the public record does not identify a specific endpoint or operation. Exploitation requires user interaction with attacker-controlled content while an authenticated management session can reach the router; the resulting configuration changes remain undisclosed.
