Fortinet Fortigate Slow HTTP DoS Attacks Mitigation (FG-IR-19-013)

high Nessus Plugin ID 209849

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the FG-IR-19-013 advisory.

 - An Uncontrolled Resource Consumption vulnerability in Fortinet FortiSwitch below 3.6.11, 6.0.6 and 6.2.2, FortiAnalyzer below 6.2.3, FortiManager below 6.2.3 and FortiAP-S/W2 below 6.2.2 may allow an attacker to cause admin webUI denial of service (DoS) via handling special crafted HTTP requests/responses in pieces slowly, as demonstrated by Slow HTTP DoS Attacks. (CVE-2019-17657)

 - The Apache HTTP Server 1.x and 2.x allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris, related to the lack of the mod_reqtimeout module in versions before 2.2.15. (CVE-2007-6750)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Please upgrade to FortiOS version 6.2.3 or later.
