Overview

Multiple Vulnerabilities have been reported in Fortinet Products which could allow an attacker to perform data manipulation, remote code execution, sensitive information disclosure, denial of service, elevation of privilege and security restriction bypass on the targeted system.

Description

Multiple vulnerabilities exist in Fortinet Products due to incorrect authorization, an improper validation of integrity check value, use of hard-coded credentials, null pointer dereference, improper authorization, an untrusted search path, an improper restriction of excessive authentication attempts, a flaw in the Curl package, and a heap-based buffer overflow flaw.  An attacker could exploit these vulnerabilities by sending a specially-crafted request to the targeted system.

Successful exploitation of these vulnerabilities could allow an attacker to perform data manipulation, remote code execution, sensitive information disclosure, denial of service, elevation of privilege and security restriction bypass on the targeted system.
