DescriptionCVE.org

A vulnerability was detected in code-projects Online Shoe Store 1.0. Affected is an unknown function of the file /admin/admin_running.php. Performing a manipulation of the argument product_name results in cross site scripting. It is possible to initiate the attack remotely. The exploit is now public and may be used.

AnalysisAI

Cross-site scripting (XSS) in code-projects Online Shoe Store 1.0 allows authenticated remote attackers with administrative privileges to inject malicious scripts via the product_name parameter in /admin/admin_running.php, requiring user interaction to execute. Publicly available exploit code exists for this vulnerability, though it carries a low CVSS score of 2.4 due to restricted attack vector (high privileges required, user interaction needed) and limited impact (integrity only).

Technical ContextAI

The vulnerability is a reflected or stored cross-site scripting (CWE-79) flaw in a PHP-based e-commerce application. The Online Shoe Store application fails to properly sanitize or encode user-supplied input in the product_name parameter before rendering it in the /admin/admin_running.php administrative interface. Because the vulnerable endpoint is within the /admin/ path and requires PR:H (high privileges), this is a privileged XSS-typically exploitable by compromised administrator accounts or through social engineering of administrators. The attack vector is network-accessible but constrained by the requirement for high administrative privileges and user interaction (UI:R), limiting the threat model to scenarios where malicious administrators attempt code injection or where legitimate administrators are tricked into clicking malicious links.

RemediationAI

Upgrade code-projects Online Shoe Store to a patched version released after version 1.0; consult the vendor at https://code-projects.org/ for specific fixed version availability. Immediate mitigation pending patching includes: implement input validation on the product_name parameter to reject or encode special characters (particularly <, >, ", &), apply output encoding to all user-controlled data rendered in HTML context, and implement Content Security Policy (CSP) headers to restrict script execution. Additionally, restrict access to /admin/admin_running.php via network-level controls (IP whitelisting) and audit administrative accounts for unauthorized modifications. The administrative nature of this vulnerability means limiting admin account distribution and enforcing multi-factor authentication for administrative panels provides defense-in-depth.
