The cybersecurity community has recently identified a critical SQL injection vulnerability in the Automotive Shop Management System (ASMS) v1.. This vulnerability, assigned the CVE number CVE-2022-44858, poses a significant risk to ASMS users, as it could potentially allow an attacker to gain unauthorized access to sensitive information, modify the application's data, and execute malicious commands. In this comprehensive guide, we will discuss the details of this vulnerability, explain how the exploit works, and outline possible mitigation strategies. We will also provide code snippets and links to original references for better understanding.

Vulnerability Details

Automotive Shop Management System (ASMS) v1. is a web application designed to help automotive repair shops manage their day-to-day operations. The vulnerability in question is a SQL injection vulnerability, which stems from the application's improper validation of input values submitted by users. The specific vulnerability lies in the "id" parameter used in the products/view_product.php file of ASMS.

Here's the affected code snippet from the application

$id = $_GET['id'];
$query = "SELECT * FROM products WHERE id = '$id'";
$result = mysqli_query($conn, $query) or die(mysqli_error($conn));

As evident from the code above, the input value of the "id" parameter is directly used in a SQL query without any proper validation or sanitation. This insecure coding practice allows an attacker to submit carefully crafted SQL statements, which may result in unauthorized database access or manipulation.

Exploit Details

To exploit this SQL injection vulnerability, an attacker can submit a malicious payload through the "id" parameter in an HTTP GET request. A sample payload could look like this:'; OR '1'='1

In this case, the resulting SQL query would be

SELECT * FROM products WHERE id = '1' OR '1'='1'

This query will return all rows in the "products" table, effectively bypassing any access control mechanisms put in place. An attacker could further manipulate the SQL statements to execute various malicious tasks, such as modifying, deleting, or adding data to the database.

Original References

The SQL injection vulnerability in ASMS v1. was initially reported by a security researcher in the following links:

1. CVE-2022-44858 - NIST National Vulnerability Database (NVD)

2. CVE-2022-44858 - Exploit Database

Mitigation Strategies

To safeguard your ASMS v1. application against this SQL injection vulnerability, consider implementing the following security measures:

1. Update the application: If an official patch or newer version addressing this vulnerability is available, be sure to promptly apply the update.

2. Input validation & sanitation: Implement proper input validation and sanitization techniques, such as prepared statements, to ensure that only legitimate data is accepted by the application.

3. Least privilege principle: Configure the application to use database accounts with minimal privileges in order to limit potential damage in the event of a successful attack.

4. Web Application Firewall (WAF): Implement a WAF, which can help detect and block malicious SQL injection attempts.


CVE-2022-44858 is a critical SQL injection vulnerability that affects the Automotive Shop Management System (ASMS) v1.. This vulnerability can be exploited by sending a malicious payload through the "id" parameter in an HTTP GET request. In order to protect your ASMS installation from this vulnerability, it is essential to apply available patches, follow secure coding practices, and implement appropriate security measures.

Stay vigilant, and remember to always prioritize the security of your web applications to ensure that your valuable data and systems remain protected against potential cyber threats.
