Lifecycle Timeline
6DescriptionCVE.org
A vulnerability was found in code-projects Simple Laundry System 1.0. This impacts an unknown function of the file /checkcheckout.php. Performing a manipulation of the argument serviceId results in cross site scripting. The attack is possible to be carried out remotely. The exploit has been made public and could be used.
AnalysisAI
Reflected cross-site scripting (XSS) in code-projects Simple Laundry System 1.0 allows unauthenticated remote attackers to inject arbitrary JavaScript via the serviceId parameter in /checkcheckout.php, requiring user interaction to execute. Publicly available exploit code exists for this vulnerability, and the low CVSS score of 4.3 reflects the need for user click-through and limited scope (integrity impact only), though the attack vector is network-accessible and requires no special privileges or authentication.
Technical ContextAI
The vulnerability is a reflected cross-site scripting (XSS) flaw classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), a common web application vulnerability class. The Simple Laundry System is a PHP-based web application, and the flaw exists in the /checkcheckout.php file where user-supplied input from the serviceId parameter is not properly sanitized or encoded before being returned in the HTTP response. This allows an attacker to craft a malicious URL containing JavaScript code that executes in the victim's browser within the security context of the vulnerable application. The affected product spans all versions of Simple Laundry System as indicated by the CPE wildcard pattern cpe:2.3:a:code-projects:simple_laundry_system:*:*:*:*:*:*:*:*.
RemediationAI
Implement input validation and output encoding on the serviceId parameter in /checkcheckout.php to prevent XSS injection. Specifically, use context-appropriate encoding (HTML entity encoding for HTML context, JavaScript escaping for JavaScript context, or URL encoding for URL context) on all user-supplied input before rendering it in the HTTP response. Additionally, implement a Content Security Policy (CSP) header to restrict script execution sources and reduce the impact of any reflected XSS. Contact code-projects at https://code-projects.org/ to request a patched version; if a patch is not available, consider disabling or restricting access to the vulnerable /checkcheckout.php endpoint until a fix is released. Web Application Firewall (WAF) rules can be configured to block requests containing common XSS payloads as a temporary mitigation.
