CVSSv3: 9.3
Fortinet has released a critical patch that remediates a newly discovered remote code execution (RCE) vulnerability. This vulnerability has been observed within the FortiOS Operating system and FortiProxy secure Web Gateway systems. Based on the information Fortinet has released, it appears the vulnerability is related to a heap buffer underflow in the administrative interface, that allows an unauthenticated user/ attacker to execute arbitrary code and or to perform a denial of service (DoS) attack on the graphical user interface (GUI).
This vulnerability has been release just 2 weeks after CVE-2022-39952 was announced for an unauthenticated RCE of FortiNAC devices.
Fortinet is not aware of any any exploitations in the wild, however Fortinet is encouraging organizations to remediate as soon as possible.
