Scans on the general public internet present that roughly 150,000 Fortinet FortiOS and FortiProxy safe internet gateway techniques are weak to CVE-2024-21762, a essential safety difficulty that permits executing code with out authentication.
America’s Cyber Protection Company CISA confirmed final month that attackers are actively exploiting the flaw by including it to its Recognized Exploited Vulnerabilities (KEV) catalog.
Susceptible variations all around the world
Virtually a month after Fortinet addressed CVE-2024-21762, The Shadowserver Basis introduced on Thursday that it discovered practically 150,000 weak gadgets.
Shadowserver’s Piotr Kijewski instructed BleepingComputer that their scans verify for weak variations, so the variety of affected gadgets could also be decrease if admins utilized mitigations as a substitute of upgrading.
A distant attacker may exploit CVE-2024-21762 (9.8 severity score as per NIST) by sending specifically crafted HTTP requests to weak machines.
In response to Shadowserver information, most weak gadgets, greater than 24,000, are in the USA, adopted by India, Brazil, and Canada.

Particulars about risk actors actively exploiting CVE-2024-21762 are presently restricted, as public platforms usually are not displaying such exercise or the vulnerability is being leveraged in choose assaults by extra subtle adversaries.
A day after Fortinet’s advisory, the Cybersecurity and Infrastructure Safety Company (CISA) confirmed active exploitation of the vulnerability by including it to its KEV catalog.
Firms can verify if their SSL VPN techniques are weak to this difficulty by operating a easy Python script developed by researchers at offensive safety firm BishopFox.
FortiOS is Fortinet’s working system with security measures comparable to safety towards denial-of-service (DoS) assaults, intrusion prevention (IPS), firewall, and VPN companies.
It powers all Fortinet Safety Cloth gadgets, from firewalls to entry factors, switches, and community entry management merchandise, offering visibility and management, centralized administration throughout the community, and constant deployment and enforcement of safety insurance policies.
