The implementation of an ANSI X9.31 RNG in Fortinet FortiGate allows attackers to gain unauthorized read access to data handled by the device via IPSec/TLS decryption.

The FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.x before 5.0.8 on FortiGate devices does not prevent use of anonymous ciphersuites, which makes it easier for man-in-the-middle attackers to obtain sensitive information or interfere with communications by modifying the client-server data stream.

The FortiManager protocol service in Fortinet FortiOS before 4.3.16 and 5.0.0 before 5.0.8 on FortiGate devices allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted request.

Multiple cross-site request forgery (CSRF) vulnerabilities in Fortinet FortiOS on FortiGate firewall devices before 4.3.13 and 5.x before 5.0.2 allow remote attackers to hijack the authentication of administrators for requests that modify (1) settings or (2) policies, or (3) restart the device via a rebootme action to system/maintenance/shutdown.
