Fortinet FortiWeb CVE-2025-25257 Vulnerability Tester

Description

This PowerShell script is designed for authorized penetration testing purposes only. It tests Fortinet FortiWeb appliances for CVE-2025-25257, an unauthenticated SQL injection vulnerability in the /api/fabric/device/status endpoint.

The script:

• Ignores TLS certificate errors for testing environments.
• Accepts a single target (IP/DNS with optional port) or a list of targets from a file.
• If no port is specified, it scans common ports: 541, 443, 10443, 8443, 4433.
• Sends an HTTP HEAD request to check endpoint accessibility.
• If accessible, sends a GET request with a SQL injection payload in the Authorization header to test for the vulnerability.

Important Disclaimer:
This tool is intended solely for ethical, authorized use in penetration testing or vulnerability assessment scenarios. Unauthorized use may violate laws such as the Computer Fraud and Abuse Act (CFAA) or equivalent regulations in your jurisdiction. Ensure you have explicit permission from the target owner before running this script. The author assumes no liability for misuse.

Requirements

• PowerShell 5.1 or later (compatible with Windows PowerShell or PowerShell Core).
• Administrative privileges may be required depending on your environment.
• No additional modules needed; uses built-in Invoke-WebRequest.

Installation

1. Clone the repository:
   root@kitploit:~

   git clone https://github.com/mr-r3b00t/CVE-2025-25257.git
   

2. Navigate to the project directory:
   root@kitploit:~

   cd CVE-2025-25257
   

The script is located at script.ps1.

Usage

Run the script from PowerShell with one of the following options:

Single Target

Specify a single IP or DNS name, optionally with a port (e.g., 192.168.1.1:443).

.\script.ps1 -Target "192.168.1.1:443"

Or without port (scans default ports):

.\script.ps1 -Target "example.com"

Input File

Provide a text file with one target per line (e.g., targets.txt).

.\script.ps1 -InputFile "targets.txt"

Example targets.txt content:

192.168.1.1:443
example.com
10.0.0.1

Output

The script will output results for each target and port, including:

• Accessibility check (HEAD request).
• Vulnerability test results (GET request with payload).
• Response status and content if applicable.

Sample Output:

Testing https://192.168.1.1:443/api/fabric/device/status for CVE-2025-25257
Endpoint accessible (HEAD 200 OK). Proceeding with GET request for vulnerability test.
GET Response Status: 200
Potential vulnerability detected (200 OK with payload). Check content for confirmation.
GET Response Content: {"devices": [...]}

How It Works

1. TLS Ignoring: Configures PowerShell to bypass certificate validation for testing.
2. Target Parsing: Handles single targets or file inputs, parsing optional ports.
3. Port Scanning: Tries predefined ports if none specified.
4. HEAD Request: Checks if the endpoint is reachable.
5. GET Request with Payload: Uses a SQL injection test in the Authorization header (Bearer AAAAAA'or'1'='1).
6. Vulnerability Indication: A 200 OK response with the payload may indicate vulnerability; manual verification is recommended.

Limitations

• This is a basic proof-of-concept tester and does not exploit the vulnerability—only tests for potential exposure.
• False positives/negatives possible; always confirm with official Fortinet advisories.
• No support for HTTP (only HTTPS).
• Timeout set to 10 seconds per request.
