How the CVE Works:
The vulnerability exists in the `/visitors-form.php` file of PHPGurukul Visitor Management System 2.0. The `fullname` parameter is improperly sanitized, allowing attackers to inject malicious SQL queries. This leads to unauthorized database access, enabling data theft, manipulation, or deletion. The flaw is remotely exploitable without authentication, increasing its severity. Attackers can craft a payload in the `fullname` field, which is concatenated directly into an SQL query, triggering the injection. Publicly disclosed exploits make this CVE highly dangerous for unpatched systems.
DailyCVE Form:
Platform: PHPGurukul CMS
Version: 2.0
Vulnerability: SQL Injection
Severity: Critical

What Undercode Say:
Exploit:
import requests
url = "http://target.com/visitors-form.php"
payload = "' OR 1=1 -- "
data = {'fullname': payload}

if (!preg_match("/^[a-zA-Z ]$/", $fullname)) {
die("Invalid input");
}
3. WAF rules:
location ~ .php$ {
deny all;
}
