Impact

The CVSS 6.9 score with vector AV:N/AC:L/AT:N/PR:N indicates a network-accessible vulnerability requiring no privileges or user interaction and low attack complexity. CVSS 4.0 scoring with E:P (Proof-of-Concept code published) reflects the realistic exploitation potential. The vulnerability lacks authentication barriers (PR:N), making it accessible to anonymous remote actors. While the impact scope is limited (VC:L/VI:L/VA:L-low confidentiality, integrity, and availability impact per the CVSS vector), SQL injection in a laundry system managing user accounts and transactions could expose personal data, modify service records, or enable privilege escalation. The public availability of exploit code elevates real-world risk despite the moderate CVSS score. This is a genuine priority for any organization running Simple Laundry System 1.0, particularly those processing personal or financial data, as SQL injection is routinely weaponized in automated scanning and mass exploitation campaigns.

Exploit ScenarioDerived

An attacker sends a POST or GET request to the /modify.php endpoint with a crafted firstName parameter containing SQL metacharacters, such as firstName=admin' OR '1'='1. The unsanitized parameter is directly concatenated into a database query, allowing the attacker to modify the query logic, bypass authentication checks, extract user data (names, payment details, account information), or alter service records within the laundry system database. Publicly released proof-of-concept code eliminates the need for skilled reverse engineering, enabling script-kiddie level exploitation at scale against deployed instances.

AnalysisAIv1 – Apr 01, 2026

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.

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.

Technical ContextAI · show details

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.
