CVE-2024-6016: Laundry Management System SQLi Flaw

CVE-2024-6016 Overview

CVE-2024-6016 is a SQL injection vulnerability in itsourcecode Online Laundry Management System 1.0. The flaw resides in the admin_class.php file, where the id parameter is concatenated into a SQL query without proper sanitization. Authenticated remote attackers can manipulate the id argument to inject arbitrary SQL statements. The issue is tracked as VDB-268724, and the exploit details have been publicly disclosed. The weakness is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Remote attackers with low privileges can inject arbitrary SQL to read, modify, or delete records in the application database, including administrative account data.

Affected Products

• itsourcecode Online Laundry Management System 1.0

Technical Details for CVE-2024-6016

Vulnerability Analysis

The vulnerability stems from improper neutralization of user-supplied input in admin_class.php. The application accepts an id argument from HTTP requests and concatenates it directly into a SQL statement. Because no parameterized queries or input filtering are applied, attackers can break out of the intended query context. Successful exploitation yields limited impact on confidentiality, integrity, and availability of the backend database, consistent with a low-privileged authenticated injection point.

Root Cause

The root cause is unsanitized inclusion of the id parameter in dynamic SQL within admin_class.php. The application does not use prepared statements, bound parameters, or strict input typing. This pattern aligns with CWE-89, Improper Neutralization of Special Elements used in an SQL Command. The flaw is typical of PHP-based projects that build queries through string concatenation against MySQL backends.

Attack Vector

The attack is launched remotely over the network against an authenticated session. An attacker submits a crafted value for the id parameter to a vulnerable endpoint handled by admin_class.php. The malicious payload modifies the SQL query logic, enabling UNION-based or boolean-based extraction of database contents. Because the exploit has been publicly disclosed, low-skill attackers can reproduce it against exposed instances. See the GitHub issue discussion and VulDB entry #268724 for technical references.

No verified exploit code is reproduced here. See the referenced VulDB and GitHub
advisory entries for disclosed technical details of the injection point in admin_class.php.

Detection Methods for CVE-2024-6016

Indicators of Compromise

• HTTP requests to endpoints handled by admin_class.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the id parameter.
• Web server access logs showing repeated requests to the same admin_class.php action with varying id values consistent with enumeration.
• Unexpected database errors or query execution time anomalies tied to requests carrying the id parameter.

Detection Strategies

• Deploy a Web Application Firewall (WAF) rule set that flags classic SQL injection patterns against the Laundry Management System admin endpoints.
• Enable MySQL general query logging or slow query logging to identify malformed or abnormally complex statements originating from the application.
• Correlate authenticated session activity with database error responses to detect injection probing.

Monitoring Recommendations

• Monitor outbound traffic from the database server for unusual data egress patterns indicating extraction.
• Track failed and successful admin logins, then correlate with subsequent requests to admin_class.php containing suspicious id values.
• Alert on web server 500-class responses generated by requests to the affected PHP files.

How to Mitigate CVE-2024-6016

Immediate Actions Required

• Restrict access to the Online Laundry Management System admin interface using network ACLs or VPN-only access until a fix is applied.
• Audit the admin_class.php file and replace dynamic SQL with prepared statements using PDO or mysqli parameterized queries.
• Rotate database and application credentials if exploitation is suspected, and review audit logs for unauthorized data access.

Patch Information

No official vendor patch is referenced in the NVD entry for CVE-2024-6016. The itsourcecode project distributes the Online Laundry Management System as source code, so remediation requires manual code changes by the operator. Refer to the VulDB submission #357463 and the GitHub issue discussion for disclosure details and community guidance.

Workarounds

• Implement server-side input validation that enforces a numeric type on the id parameter before it reaches any SQL statement.
• Deploy WAF rules that block SQL injection signatures targeting admin_class.php.
• Apply the principle of least privilege to the database account used by the application, removing rights such as DROP, ALTER, and FILE.

# Example PHP remediation pattern using PDO prepared statements
$stmt = $pdo->prepare('SELECT * FROM users WHERE id = :id');
$stmt->bindValue(':id', (int)$_POST['id'], PDO::PARAM_INT);
$stmt->execute();
