How the CVE Works:
CVE-2025-28867 is a critical Cross-Site Request Forgery (CSRF) vulnerability in the Stesvis Frontpage category filter. This flaw allows attackers to trick authenticated users into executing unintended actions on the web application without their knowledge. The vulnerability exists in versions from n/a through 1.0.2 of the Frontpage category filter. By crafting a malicious request and luring a user to click on a link or visit a compromised page, an attacker can exploit this flaw to perform actions such as modifying filters, altering settings, or stealing sensitive data. The lack of proper CSRF tokens or validation mechanisms in the affected versions makes this exploitation possible.
DailyCVE Form:
Platform: Stesvis Frontpage
Version: 1.0.2 and earlier
Vulnerability: CSRF
Severity: Critical
Date: 03/11/2025
What Undercode Say:
Exploitation:
- Craft a malicious HTML form or link targeting the Frontpage category filter endpoint.
- Trick an authenticated user into clicking the link or visiting the malicious page.
- The user’s browser sends the forged request to the server, executing the attacker’s desired action.
Protection:
1. Implement CSRF tokens in all state-changing requests.
- Validate the origin and referrer headers for incoming requests.
3. Use SameSite cookies to prevent cross-origin requests.
Commands and Code:
1. Generate CSRF Token (PHP Example):
<?php
session_start();
if (empty($_SESSION[bash])) {
$_SESSION[bash] = bin2hex(random_bytes(32));
}
?>
<input type="hidden" name="csrf_token" value="<?php echo $_SESSION[bash]; ?>">
2. Validate CSRF Token (PHP Example):
<?php
session_start();
if ($_POST[bash] !== $_SESSION[bash]) {
die("CSRF token validation failed.");
}
?>
3. Enable SameSite Cookies (Apache .htaccess):
Header edit Set-Cookie ^(.)$ "$1; SameSite=Strict"
4. Check Referrer Header (Node.js Example):
app.use((req, res, next) => {
const referrer = req.get('Referrer');
if (!referrer || !referrer.startsWith('https://yourdomain.com')) {
return res.status(403).send('Invalid request origin');
}
next();
});
5. Exploit PoC (Malicious HTML):
<form action="https://target.com/frontpage/filter" method="POST"> <input type="hidden" name="action" value="delete_all"> </form> <script>document.forms[bash].submit();</script>
Analytics:
- Attack Vector: Network (exploitable remotely).
- Impact: Confidentiality, Integrity, and Availability are compromised.
- Mitigation Complexity: Low (requires code changes and proper validation).
- Affected Users: All users of Stesvis Frontpage versions 1.0.2 and earlier.
By following the above steps, developers can mitigate this critical vulnerability and protect their applications from CSRF attacks.
