Fortinet FortiGate contain multiple vulnerabilities that could allow an unauthenticated, remote attacker to conduct cross-site request forgery attacks on the targeted system. Updates are available.
Multiple vulnerabilities in Fortinet FortiGate versions 4.3.13 and 5.x prior to 5.0.2 could allow an unauthenticated, remote attacker to conduct cross-site request forgery attacks on the targeted system.
The vulnerabilities are due to improper validation of certain user-supplied HTTP requests by the system/maintenance/shutdown form. An attacker could exploit these vulnerabilities by convincing a user to visit a malicious webpage that is designed to submit malformed HTTP requests via a rebootme action to the vulnerable form. Successful exploitation could allow an attacker to perform certain unauthorized actions such as modifying settings, policies, or restarting the device on behalf of the user.
Proof-of-concept code that exploits these vulnerabilities is publicly available.
Users should verify that unsolicited links are safe to follow.
