FortiOS & FortiProxy SSL-VPN Flaw Allows IP Spoofing via Malicious Packets

A critical vulnerability has been discovered in Fortinet’s FortiOS SSL-VPN and FortiProxy SSL-VPN.

The flaw, identified as FG-IR-23-225, allows attackers to spoof IP addresses and bypass security controls by sending specially crafted packets. It affects multiple versions of FortiOS and FortiProxy.

According to the advisory published by Fortinet, the vulnerability stems from improper validation of packets within the SSL-VPN portal and proxy services.

An attacker can exploit this issue by crafting malicious packets that manipulate the source IP address, effectively spoofing their identity and potentially gaining unauthorized access to protected network resources.

Live API Attack Simulation

94% of organizations experience security problems in production APIs, and one in five suffers a data breach. As a result, cyber-attacks on APIs increased from 35% in 2022 to 46% in 2023, and this trend continues to rise.
Key takeaways include:

  • An exploit of OWASP API Top 10 vulnerability
  • A brute force ATO (Account Takeover) attack on API
  • A DDoS attack on an API
  • Positive security model automation to prevent API attacks
