Readme

# CVE-2024-53376
CyberPanel Authenticated OS Command Injection

### Affected Devices
CyberPanel versions < 2.3.8 are vulnerable to an OS command injection. To exploit the vulnerability the attacker is required to firstly login to the webpanel. 

### Tested With
CyberPanel 2.3.7

### Technical details

An attacker can use a HTTP OPTIONS request to instruct the webserver running the CyberPanel application to execute arbitrary commands. This vulnerability lies in the /websites/submitWebsiteCreation endpoint.

This endpoint calls the submitWebsiteCreation function in the /websiteFunctions/views.py file location.

This function further calls the `wm.submitWebsiteCreation` function found in the /websiteFunctions/website.py file. This function extracts five parameters which are used within the function:
    - domain;
    - adminEmail;
    - phpSelection;
    - packageName;
    - websiteOwner;

These parameters are later parsed directly to a function that executes these:

The Proof-of-Concept (PoC) code can be found in the cyberpanel.py file that is linked in this repo.

### PoC

This Proof-of-Concept can be used to write files with root level permissions, anywhere on the system:

This could result in a complete device compromise. If the device's CyberPanel installation folder is accessible, data can be more easily extracted through the web panel.
