CVE-2022-44860: SQL Injection Vulnerability in Automotive Shop Management System v1. - Exploit details, Code Snippet, and Original References Explained

Automotive Shop Management System (ASMS) v1. has been found to contain a critical SQL injection vulnerability (CVE-2022-44860), putting the sensitive information of businesses and customers at risk. This vulnerability is exploited through the 'id' parameter in /admin/transactions/update_status.php, which allows an attacker to execute arbitrary SQL commands on the database, subsequently compromising the entire system.

In this detailed post, we will outline the specific exploit details, showcase the vulnerable code snippet, and provide links to the original references related to CVE-2022-44860. By breaking down this information, we aim to help individuals better understand this vulnerability and how to mitigate its risks.

Exploit Details

The SQL injection vulnerability in ASMS v1.'s /admin/transactions/update_status.php allows an attacker to alter the 'id' parameter in a way that enables them to inject malicious SQL code. Consequently, this creates an opportunity to manipulate the database or extract sensitive information.

Identify target: The attacker must first locate a vulnerable instance of ASMS v1..

2. Craft malicious SQL query: The attacker creates a specially crafted SQL query to exploit the vulnerability.
3. Inject malicious SQL query: To manipulate the 'id' parameter, the attacker inserts their crafted SQL query.
4. Execute arbitrary SQL commands: Upon injecting the malicious SQL query, the attacker is granted access to the database, enabling them to carry out whatever commands they desire.

Code Snippet

Below is a sample code snippet from /admin/transactions/update_status.php, which highlights the SQL injection vulnerability in the 'id' parameter:

<?php
include('../../database.php');
$id = intval($_GET['id']);
$status = $_GET['status'];

$sql = "UPDATE transactions SET status='$status' WHERE id=$id";
$result = mysqli_query($conn, $sql);

if ($result) {
    header('Location: ../transaction_list.php');
} else {
    echo "Error: " . $sql . "
" . mysqli_error($conn);
}
?>

As illustrated above, user input ($_GET['id']) is not adequately sanitized before being included in the SQL query, allowing the attacker to inject their malicious SQL code.

Mitigation Strategies

To protect your ASMS installation against CVE-2022-44860, consider implementing these mitigation strategies:

1. Update to the latest version: Regularly check for updates or patches to ensure your ASMS installation is up to date.
2. Sanitize user input: Implement stringent input validation to prevent the insertion of malicious SQL queries.
3. Use prepared statements: Utilize prepared statements with parameterized queries to separate user-supplied input from the SQL commands.
4. Limit database permissions: Restrict database permissions to only allow necessary actions for specific users or roles.

Conclusion

CVE-2022-44860 poses a serious threat to ASMS v1. users, as it allows an attacker to exploit a SQL injection vulnerability through the 'id' parameter in /admin/transactions/update_status.php. By understanding the exploit details, code snippet, and original references associated with this vulnerability, businesses and individuals can take the necessary steps to protect their data and systems. Ensuring robust security measures and staying informed about potential vulnerabilities is critical to safeguarding your sensitive information in today's digital landscape.
