The Qilin ransomware group is exploiting two critical Fortinet vulnerabilities in recent attacks. The flaws, CVE-2024-55591 and CVE-2024-21762, allow threat actors to bypass authentication and remotely execute code . Despite previous exploitation of these vulnerabilities by various cyber threat groups, thousands of devices remain vulnerable to the flaws. Administrators of impacted Fortinet devices are highly advised to address these vulnerabilities immediately, updating systems or applying mitigations.
