How the Mentioned CVE Works:
The vulnerability in Froxlor, identified as CVE-2023-XXXX, allows authenticated users (such as resellers or customers) to create accounts using the same email address as an existing account. For example, if an admin account exists with the email [email protected], another user can register an account with the same email. This flaw arises due to insufficient validation during the account creation process, where the system fails to enforce email uniqueness. As a result, multiple accounts can share the same email, leading to potential security conflicts, misidentification, and unauthorized access to sensitive information. The attack vector is email-based, and the impact is primarily on account management and system integrity.
DailyCVE Form:
Platform: Froxlor
Version: Pre-2.0.10
Vulnerability: Account Duplication
Severity: Medium
Date: 2023-10-15
What Undercode Say:
Exploitation:
1. Exploit Scenario:
An attacker with authenticated access (e.g., a reseller) can create a new account using the same email as an admin account. This could lead to confusion in account management and potential privilege escalation if the system relies on email for identification.
2. Exploit Command:
Use the account creation API or web interface to register a new account with a duplicate email:
curl -X POST -d "[email protected]&password=attacker123" http://froxlor-server/create-account
3. Impact Analysis:
- Misidentification of accounts during login or password recovery.
- Potential for unauthorized access to admin-level resources if the system uses email as a primary identifier.
Protection:
1. Patch Application:
Upgrade to Froxlor version 2.0.10 or later, where this vulnerability has been patched.
2. Manual Fix:
Implement email uniqueness validation in the account creation process:
// Example PHP code to enforce email uniqueness
$email = $_POST[bash];
$stmt = $pdo->prepare("SELECT FROM users WHERE email = ?");
$stmt->execute([bash]);
if ($stmt->rowCount() > 0) {
die("Email already exists.");
}
3. Mitigation Steps:
- Review and audit existing accounts for duplicate emails.
- Implement multi-factor authentication (MFA) to reduce the risk of unauthorized access.
- Monitor logs for suspicious account creation attempts.
4. Logging and Monitoring:
Enable detailed logging for account creation events:
tail -f /var/log/froxlor/account_creation.log
5. Security Best Practices:
- Regularly update Froxlor to the latest version.
- Conduct periodic security audits to identify similar vulnerabilities.
- Educate users about the risks of sharing email addresses across accounts.
By following these steps, administrators can mitigate the risks associated with CVE-2023-XXXX and ensure the security of their Froxlor installations.
