DescriptionCVE.org

A flaw has been found in code-projects Simple Laundry System 1.0. This vulnerability affects unknown code of the file /modify.php of the component Parameter Handler. This manipulation of the argument firstName causes sql injection. Remote exploitation of the attack is possible. The exploit has been published and may be used.

AnalysisAI

SQL injection in code-projects Simple Laundry System 1.0 allows unauthenticated remote attackers to manipulate the firstName parameter in /modify.php, enabling arbitrary database queries and potential data exfiltration or modification. The vulnerability affects the Parameter Handler component through CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). Publicly available exploit code exists, and the CVSS 6.9 score reflects moderate impact with low attack complexity and no authentication requirement.

Technical ContextAI

The vulnerability exists in the Parameter Handler component of Simple Laundry System 1.0, specifically within the /modify.php file. The root cause is classified as CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which indicates insufficient input validation or sanitization of user-supplied parameters before use in SQL queries. The firstName parameter is passed unsanitized into a downstream SQL context, allowing attackers to inject arbitrary SQL commands. This is a classic PHP-based SQL injection flaw where user input is concatenated directly into query strings without prepared statements or parameterized query mechanisms.

RemediationAI

Immediate mitigation requires upgrading Simple Laundry System to a patched version if available from code-projects.org; however, no explicit patched version number is confirmed in the available data. Users unable to upgrade immediately should implement input validation and parameterized queries (prepared statements) for the firstName parameter in /modify.php to prevent SQL injection. Recommended steps: (1) Replace all string concatenation in SQL queries with parameterized prepared statements using PHP's mysqli or PDO libraries; (2) Apply strict input validation to reject or escape special SQL characters in the firstName field; (3) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in /modify.php requests; (4) Review database user permissions to apply least-privilege principles, limiting the laundry system's database account to only necessary operations. Additional technical guidance is available from the VulDB submission and GitHub issue referenced at https://github.com/kunlan567-boop/test/issues/1 and https://vuldb.com/vuln/354446.
