Impact

This vulnerability presents a significant real-world risk despite being in a niche application. The CVSS score of 7.3 (High) reflects the network-based attack vector with low complexity and no privilege requirements, enabling unauthenticated remote exploitation. The availability of a public proof-of-concept exploit (https://github.com/zzb1388/cve2/issues/1) dramatically increases exploitation likelihood, as attackers can leverage existing code without developing their own exploits. The CVSS environmental metrics show Exploit Maturity as Proof-of-concept (E:P), confirming active exploit availability. While there is no indication of KEV listing or active widespread exploitation, the low technical barrier combined with public exploit code makes this a genuine priority for organizations running this software. The impact allows confidentiality, integrity, and availability compromise (C:L/I:L/A:L), enabling data theft, modification, and potential service disruption. Organizations should treat this as high-priority despite the software's limited deployment footprint.

Exploit ScenarioDerived

An unauthenticated attacker identifies a Simple Laundry System installation and accesses the publicly available proof-of-concept from GitHub (https://github.com/zzb1388/cve2/issues/1). The attacker crafts a malicious HTTP request to /checkcheckout.php with a SQL injection payload in the serviceId parameter, such as injecting UNION-based queries to extract sensitive data from the database including customer information, payment records, or administrative credentials. With low attack complexity and no authentication required, the attacker can automate this exploitation across multiple installations to harvest data or modify pricing information and transaction records.

AnalysisAIv1 – Mar 25, 2026

SQL injection in Simple Laundry System 1.0 PHP application allows unauthenticated remote attackers to execute arbitrary database queries through the serviceId parameter in /checkcheckout.php. Public exploit code exists for this vulnerability, and no patch is currently available.

Earlier versions of this analysis (1)
v1 Mar 25, 2026 - 01:45 CVSS 6.9

A SQL injection vulnerability exists in Simple Laundry System version 1.0, specifically in the /checkcheckout.php file's Parameter Handler component where the serviceId parameter is not properly sanitized. This remotely exploitable vulnerability requires no authentication or user interaction (CVSS AV:N/AC:L/PR:N/UI:N), allowing attackers to access, modify, or delete database information. A public proof-of-concept exploit has been published on GitHub, significantly lowering the barrier to exploitation.

RemediationAI

No official patch or updated version has been identified in the available references, as indicated by the CVSS Remediation Level of Unavailable (RL:X). Organizations running Simple Laundry System 1.0 should immediately implement input validation and parameterized queries for the serviceId parameter in /checkcheckout.php as a code-level fix. As interim mitigations, deploy a web application firewall (WAF) configured with SQL injection detection rules to filter malicious requests targeting this parameter, restrict network access to the application to trusted IP ranges only, implement principle of least privilege for the database user account used by the application to limit potential damage from successful exploitation, and conduct thorough logging and monitoring of all requests to /checkcheckout.php for anomalous patterns. Consider replacing the application with a maintained alternative if vendor support and patching are not forthcoming, as the application appears to be an unmaintained code project based on the distribution source.

Technical ContextAI · show details

The vulnerability affects code-projects Simple Laundry System 1.0 (CPE: cpe:2.3:a:code-projects:simple_laundry_system:*:*:*:*:*:*:*:*), a PHP-based web application for managing laundry services. The root cause is CWE-89 (SQL Injection), which occurs when user-supplied input is not properly validated or sanitized before being incorporated into SQL queries. In this case, the serviceId parameter in the /checkcheckout.php file's Parameter Handler is vulnerable to SQL injection attacks, allowing attackers to manipulate database queries by injecting malicious SQL commands. This represents a fundamental input validation failure in the application's database interaction layer.

DescriptionCVE.org

A vulnerability was found in code-projects Simple Laundry System 1.0. This affects an unknown function of the file /checkcheckout.php of the component Parameter Handler. The manipulation of the argument serviceId results in sql injection. It is possible to launch the attack remotely. The exploit has been made public and could be used.

Executive ViewAI

Why It Matters

A critical SQL injection vulnerability in Simple Laundry System version 1.0 allows unauthenticated attackers to remotely access, modify, or delete database information without authentication. With a public exploit available and no patch currently available, this poses an immediate risk to data integrity and confidentiality for any organization using this system.

Business Impact: Severe
Compensating Controls

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the serviceId parameter; restrict network access to /checkcheckout.php through firewall rules or IP whitelisting; disable the checkout functionality until a patch is available if operationally feasible; implement database activity monitoring (DAM) to detect unauthorized queries; apply principle of least privilege to database service accounts; consider running the application in a segregated network segment with restricted outbound access.
