How the CVE Works:
CVE-2025-25379 is a CSRF vulnerability in 07FLYCMS v1.3.9 that allows remote attackers to execute arbitrary code via the `id` parameter in the `del.html` component. The flaw occurs due to insufficient anti-CSRF token validation, enabling an attacker to craft a malicious request that triggers unauthorized actions when an authenticated admin visits a malicious page. The `del.html` endpoint fails to verify the origin of requests, permitting unintended deletions or code execution.
DailyCVE Form:
Platform: 07FLYCMS
Version: 1.3.9
Vulnerability: CSRF → RCE
Severity: Critical
Date: 04/15/2025
What Undercode Say:
Exploit:
<!-- Malicious page exploiting CSRF --> <form action="http://target.com/del.html" method="POST"> <input type="hidden" name="id" value="malicious_payload"> </form> <script>document.forms[bash].submit();</script>
Protection:
1. Implement CSRF tokens:
<?php session_start(); $csrf_token = bin2hex(random_bytes(32)); $_SESSION['csrf_token'] = $csrf_token; ?> <input type="hidden" name="csrf_token" value="<?php echo $csrf_token; ?>">
2. Validate tokens server-side:
if ($_POST['csrf_token'] !== $_SESSION['csrf_token']) {
die("CSRF validation failed.");
}
3. Use SameSite cookies:
php.ini or .htaccess session.cookie_samesite = "Strict"
Detection:
curl -v http://target.com/del.html -d "id=test" -H "Origin: evil.com"
Mitigation Commands:
- Patch via vendor update.
- Disable `del.html` if unused:
chmod 000 /var/www/html/del.html
Log Analysis:
grep "POST /del.html" /var/log/apache2/access.log | cut -d ' ' -f1 | uniq
