How to Protect Your SourceCodester Eyewear Shop

To mitigate the risk posed by CVE-2024-9906, it is crucial to implement proper input sanitization and validation techniques. Specifically, ensure that any Code argument passed to the vulnerable file (/admin/?page=inventory/view_inventory&id=2) doesn't contain script tags or other malicious content.

Here's an example of input sanitization using PHP

$code = htmlspecialchars($_GET['code'], ENT_QUOTES, 'UTF-8');

This single line of code performs input sanitization by converting special characters, such as <, >, and &, to their respective HTML entity equivalents, thus preventing code execution.

Furthermore, SourceCodester's developers are urged to investigate this vulnerability issue, patch it, and release an updated version of the Online Eyewear Shop application to protect its users from exploitation.
