Fortinet has been a leading technological innovator, offering advanced security solutions like its FortiGate Next-Generation Firewall (NGFW) to numerous companies across the globe. The FortiGate platform’s robust security features have become a go-to solution for businesses looking to protect their infrastructure against the latest cyber threats. However, recently, cybersecurity researchers have uncovered a FortiGate security vulnerability (CVE-2023-29183) in the FortiGate platform.

This vulnerability could allow an authenticated attacker to trigger malicious JavaScript code execution, and can be exploited by a hacker through specifically crafted guest management settings – thus putting your network at risk.

As a senior IT decision-maker, it is essential to stay on top of the latest security threats and how to avoid them. In this blog post, we’ll explore the FortiGate security advisory (FG-IR-23-106) and how you can protect your network.

Understanding The FortiGate Security Vulnerability

The FortiGate security vulnerability can be exploited by a hacker through its guest management settings, which are accessible by an authenticated HTTP session on the FortiGate interface. The attacker can inject malicious JavaScript code into the guest management page, which will then execute when an authorized user views it.

The exploitation of this vulnerability can lead to significant consequences for your business, and the execution of malicious code can allow an attacker to gain complete control of your network – stealing sensitive data and causing serious financial and reputational damage.
