How CVE-2025-3819 Works
This vulnerability exists in PHPGurukul Men Salon Management System 1.0 due to improper input sanitization in the `/admin/search-appointment.php` file. The `searchdata` parameter is directly concatenated into an SQL query without validation, allowing attackers to inject malicious SQL commands. Remote exploitation is possible via crafted HTTP requests, leading to unauthorized database access, data manipulation, or system compromise. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) confirms its network-based attack vector with low attack complexity and high impact on confidentiality, integrity, and availability.
DailyCVE Form
Platform: PHPGurukul
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/14/2025
What Undercode Say:
Exploitation
POST /admin/search-appointment.php HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded searchdata=' UNION SELECT 1,2,3,4,5,user(),7,8,9-- -
Detection
sqlmap -u "http://target.com/admin/search-appointment.php" --data="searchdata=test" --risk=3 --level=5
Mitigation
1. Patch:
// Fix: Parameterized queries
$stmt = $conn->prepare("SELECT FROM appointments WHERE customer_name LIKE ?");
$stmt->bind_param("s", "%".$_POST['searchdata']."%");
2. WAF Rule:
location /admin/ {
modsecurity_rules 'SecRule ARGS:searchdata "@detectSQLi" deny';
}
3. Log Analysis:
grep -E "UNION|SELECT|--|sleep()" /var/log/apache2/access.log
4. Temporary Workaround:
iptables -A INPUT -p tcp --dport 80 -m string --string "searchdata=" --algo bm -j DROP
5. Database Hardening:
REVOKE ALL PRIVILEGES ON . FROM 'app_user'@'%'; GRANT SELECT ONLY ON salon_db. TO 'app_user'@'localhost';
Indicators of Compromise (IoC)
- Abnormal SQL errors in logs
- Unexpected database entries
- Unauthorized admin panel access
