SourceCodester Client Database Management System (CDMS) version 1.0 faces a critical SQL Injection vulnerability, CVE-2025-46189, posing a significant threat to sensitive data. This flaw, residing in the user_order_customer_update.php
file, allows attackers to inject malicious SQL queries via the order_id
POST parameter. This article provides security professionals with the necessary information to understand, detect, and mitigate this vulnerability, safeguarding their systems from potential compromise.
SourceCodester Client Database Management System (CDMS) is a web application designed to manage client databases, orders, and customer-related information. Commonly used by small to medium-sized businesses, this system helps streamline customer relationship management and order processing. Its functionalities include storing client details, managing order histories, and facilitating updates to customer information. The system's reliance on database interactions makes it a prime target for SQL injection attacks, emphasizing the importance of robust security measures.
CVE ID: CVE-2025-46189
Description: SQL Injection vulnerability in SourceCodester Client Database Management System version 1.0, specifically in the user_order_customer_update.php
file.
CVSS Score: 9.8 (Critical)
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CVE-2025-46189 is a critical SQL injection vulnerability found within the user_order_customer_update.php
file of SourceCodester Client Database Management System version 1.0. It allows a remote, unauthenticated attacker to inject arbitrary SQL commands through the order_id
POST parameter. The lack of proper sanitization and validation of the order_id
input enables malicious actors to manipulate database queries. This vulnerability stems from inadequate neutralization of special elements used within SQL commands, categorized as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')).
The impact of CVE-2025-46189 is severe. Successful exploitation could allow an attacker to bypass authentication, read sensitive database contents, modify or delete database records, and execute unauthorized database operations. This could lead to a complete compromise of the database, potentially exposing customer information, order details, and other critical system data. The potential consequences include data breaches, financial losses, reputational damage, and legal liabilities. A compromised database could also serve as a launchpad for further attacks on interconnected systems, amplifying the overall impact.

To determine if your SourceCodester CDMS is vulnerable, examine the user_order_customer_update.php
file. Manually analyze the code to identify whether the order_id
POST parameter is properly sanitized before being used in SQL queries.
Code Review:
Inspect the user_order_customer_update.php
file.
Check for any SQL queries that directly use the $_POST['order_id']
value without prior sanitization or parameterization.
Manual Testing:
Submit a POST request to user_order_customer_update.php
with a malicious order_id
value, such as: ' OR '1'='1
.
Monitor the database server for any errors or unexpected behavior.
If the application returns sensitive data or allows modifications without proper authentication, the system is likely vulnerable.
Addressing CVE-2025-46189 requires immediate action to secure the SourceCodester CDMS. The primary remediation strategy involves implementing robust input validation and using parameterized queries.
Input Validation:
Implement strict input validation for the order_id
POST parameter.
Use whitelisting to allow only numeric values.
Reject any input containing special characters or SQL keywords.
Parameterized Queries (Prepared Statements):
Rewrite the vulnerable SQL queries to use parameterized queries or prepared statements.
Parameterized queries ensure that user input is treated as data, not as executable code, preventing SQL injection.
Example (using PDO in PHP):
$order_id = $_POST['order_id'];
$stmt = $pdo->prepare("SELECT * FROM orders WHERE order_id = ?");
$stmt->execute([$order_id]);
$results = $stmt->fetchAll();
Principle of Least Privilege:
Ensure that the database user account used by the application has only the necessary permissions.
Limit access to specific tables and operations to minimize the impact of a successful SQL injection attack.
Security Audit:
Conduct a thorough security audit of the entire application to identify and address any other potential vulnerabilities.
Monitor Official Channels:
Since the patch status is not explicitly confirmed, continuously monitor official SourceCodester channels for any security updates or patches related to this vulnerability.
Apply any released patches promptly.
Temporary Isolation:
Consider temporarily isolating the affected system until a fix is available to prevent potential exploitation.
By implementing these measures, organizations can significantly reduce the risk posed by CVE-2025-46189 and protect their SourceCodester CDMS from SQL injection attacks.
