Posted by [Systems Engineering](https://blog.systemsengineering.com/blog/author/systems-engineering)

Systems Engineering is aware of two Critical Vulnerabilities, the Fortinet FortiOS - Out-of-bound Write in sslvpnd ([CVE-2024-21762](https://www.fortiguard.com/psirt/FG-IR-24-015)) and FortiOS - Format String Bug in fgfmd ([CVE-2024-23113](https://www.fortiguard.com/psirt/FG-IR-24-029)). 

Fortinet rates this vulnerability as CRITICAL. 

### Description

Fortinet has announced two vulnerabilities, one in the SSLVPNd system that could allow an unauthenticated, remote attacker to execute arbitrary code or commands via crafted HTTP or HTTPS requests. The second vulnerability uses the fgfmd (Fortimanager connector) system that could allow an unauthenticated, remote attacker to execute arbitrary code or commands. A successful attack would allow a malicious attacker to run administrative commands on the FortiGate, compromising the device's integrity.

Please Note that this is potentially being exploited in the wild, according to Fortinet. 

### Scope

This vulnerability is specific to FortiGate FortiOS. From the Fortinet Product Security Incident Response Team (PSIRT) Advisory webpage, the following systems are affected:   

CVE-2024-21762: ![CVE-2024-21762--1](https://blog.systemsengineering.com/hs-fs/hubfs/CVE-2024-21762--1.png?width=500&height=175&name=CVE-2024-21762--1.png)

CVE-2024-23113:![CVE-2024-23113-1](https://blog.systemsengineering.com/hs-fs/hubfs/CVE-2024-23113-1.png?width=500&height=89&name=CVE-2024-23113-1.png)

### Course of Action

Fortinet has released a patch to remediate affected systems.
