1.0.1
A problematic cross-site scripting (XSS) vulnerability has been identified in SourceCodester Medicine Tracker System versions 1.0 through 1.0. This flaw allows attackers to inject malicious scripts by manipulating the 'page' parameter within the index.php file. Successful exploitation could lead to session hijacking and data theft. A patch is available in version 1.0.1.
The XSS vulnerability in Medicine Tracker System allows an attacker to execute arbitrary JavaScript code within the context of a user's browser. This can be leveraged to steal session cookies, redirect users to malicious websites, or deface the application. An attacker could potentially gain unauthorized access to sensitive patient data stored within the system, depending on user privileges and data handling practices. The impact is amplified if the system is used in a healthcare setting, where patient confidentiality is paramount.
This vulnerability has been publicly disclosed and a proof-of-concept may be available. It is not currently listed on the CISA KEV catalog. The LOW CVSS score suggests a relatively low probability of exploitation, but the ease of exploitation and potential impact warrant immediate attention. The vulnerability's presence in a healthcare application increases the potential for significant consequences.
Healthcare providers and organizations utilizing the Medicine Tracker System, particularly those with legacy configurations or shared hosting environments, are at risk. Systems handling sensitive patient data are especially vulnerable and require immediate remediation.
• php: Examine index.php for unsanitized use of the 'page' parameter. Search for instances where user input is directly outputted without proper encoding.
// Example: Check for direct output of $_GET['page']
if (isset($_GET['page'])) {
echo $_GET['page']; // Vulnerable
}• generic web: Use curl to test for XSS by injecting <script>alert(1)</script> into the 'page' parameter and observing the response.
curl 'http://your-medicine-tracker-system/index.php?page=<script>alert(1)</script>' • generic web: Review access and error logs for suspicious requests containing XSS payloads.

The primary mitigation for CVE-2023-5581 is to immediately upgrade to version 1.0.1 of Medicine Tracker System. If upgrading is not immediately feasible, consider implementing input validation and output encoding on the 'page' parameter in index.php to sanitize user-supplied data. Web application firewalls (WAFs) configured to detect and block XSS payloads can also provide a temporary layer of protection. Regularly review and update the application's security configuration to minimize the attack surface.
Actualizar a una versión parcheada o aplicar las medidas de seguridad necesarias para evitar la ejecución de código XSS. Validar y limpiar las entradas del usuario, especialmente el parámetro 'page' en index.php, antes de mostrarlo en la página.
