Critical Fortinet flaw may impact 150,000 exposed devices
Scans on the public web show that approximately 150,000 Fortinet FortiOS and FortiProxy secure web gateway systems are vulnerable to CVE-2024-21762, a critical security issue that allows executing code without authentication. America’s Cyber Defense Agency CISA confirmed last month that attackers are actively exploiting the flaw by adding it to its Known Exploited Vulnerabilities (KEV) catalog.
Almost a month after Fortinet addressed CVE-2024-21762, The Shadowserver Foundation announced on Thursday that it found nearly 150,000 vulnerable devices. Shadowserver’s Piotr Kijewski told BleepingComputer that their scans check for vulnerable versions, so the number of affected devices may be lower if admins applied mitigations instead of upgrading. According to Shadowserver data, most vulnerable devices, more than 24,000, are in the United States, followed by India, Brazil, and Canada.
