Fortinet FortiOS Web Interface Cookie Parser RCE (EGREGIOUSBLUNDER)

Description

The Fortinet FortiOS management console running on the remote host is affected by a remote code execution vulnerability, known as EGREGIOUSBLUNDER, in its web interface due to improper validation when parsing cookies. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request, to cause a buffer overflow condition, resulting in a denial of service condition or the execution of arbitrary code. EGREGIOUSBLUNDER is one of multiple Equation Group vulnerabilities and exploits disclosed on 2016/08/14 by a group known as the Shadow Brokers. Note that this plugin attempts to kill the httpsd process, which appears to restart after termination. Additionally, this plugin requires report paranoia as it relies on a missing server response to indicate a vulnerable status, which may or may not be reliable.
