Security News > 2024 > February > New Fortinet RCE flaw in SSL VPN likely exploited in attacks
Fortinet is warning that a new critical remote code execution vulnerability in FortiOS SSL VPN is potentially being exploited in attacks.
For those unable to apply patches, you can mitigate the flaw by disabling SSL VPN on your FortiOS devices.
Threat actors commonly target Fortinet flaws to breach corporate networks for ransomware attacks and cyber espionage.
Yesterday, Fortinet disclosed that Chinese state-sponsored threat actors known as Volt Typhoon targeted FortiOS vulnerabilities to deploy custom malware known as COATHANGER. This malware is a custom remote access trojan designed to infect Fortigate network security appliances and was recently found used in attacks on the Dutch Ministry of Defence.
Due to the high severity of the newly disclosed CVE-2024-21762 flaw and the likelihood of it being exploited in attacks, it is strongly advised that you update your devices as soon as possible.
Fortinet warns of new FortiSIEM RCE bugs in confusing disclosure.
