How the Mentioned CVE Works:
CVE-2025-28866 is a Cross-Site Request Forgery (CSRF) vulnerability found in the Login Logger plugin. This vulnerability allows attackers to trick authenticated users into executing unintended actions on the web application without their knowledge. When a user is logged into the application, an attacker can craft a malicious request (e.g., changing user settings or logging out) and send it to the application via a forged link or form. If the user clicks the link or submits the form while authenticated, the application processes the request as legitimate, leading to unauthorized actions. This vulnerability affects Login Logger versions from n/a through 1.2.1.
DailyCVE Form:
Platform: Login Logger
Version: 1.2.1 and earlier
Vulnerability: CSRF
Severity: Medium
Date: 03/11/2025
What Undercode Say:
Exploitation:
1. Crafting Malicious Requests:
Attackers create forged requests targeting authenticated users.
Example:
<form action="http://target-site.com/change-password" method="POST"> <input type="hidden" name="new_password" value="hacked123"> </form> <script>document.forms[bash].submit();</script>
2. Social Engineering:
Attackers trick users into clicking malicious links or visiting compromised websites.
Example:
<a href="http://target-site.com/logout">Click here for a free gift!</a>
3. Exploit Execution:
When the user clicks the link or visits the page, the malicious request is sent with the user’s session, executing the action.
Protection:
1. CSRF Tokens:
Implement unique CSRF tokens for each session and validate them on the server side.
Example:
session_start();
if ($_SERVER[bash] === 'POST') {
if (!isset($_POST[bash]) || $_POST[bash] !== $_SESSION[bash]) {
die("CSRF validation failed.");
}
}
$_SESSION[bash] = bin2hex(random_bytes(32));
2. SameSite Cookies:
Set the `SameSite` attribute for cookies to prevent cross-origin requests.
Example:
setcookie('session_id', $sessionId, [bash]);
3. Input Validation:
Validate and sanitize all user inputs to prevent malicious payloads.
Example:
$new_password = htmlspecialchars($_POST[bash], ENT_QUOTES, 'UTF-8');
4. Security Headers:
Use security headers like `Content-Security-Policy` to mitigate risks.
Example:
Header set Content-Security-Policy "default-src 'self'; script-src 'self';"
5. Patch Management:
Update Login Logger to the latest version or apply patches provided by the vendor.
Analytics:
- Attack Vector: Network
- Complexity: Low
- Privileges Required: None
- User Interaction: Required
- Scope: Unchanged
Commands:
- Check for Vulnerable Versions:
grep -r "Login Logger Version" /var/www/html/
- Generate CSRF Token:
openssl rand -hex 32
- Test CSRF Protection:
Use tools like Burp Suite or OWASP ZAP to test for CSRF vulnerabilities.
By following these steps, users can mitigate the risks associated with CVE-2025-28866 and secure their applications against CSRF attacks.
