SourceCodester Inventory System Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in SourceCodester Inventory System version 1.0. The issue resides in the view_category.php file, where the application fails to properly sanitize the 'limit' parameter in GET requests. This lack of input validation allows remote attackers to inject arbitrary web scripts or HTML. The vulnerability can be exploited to target logged-in administrators, potentially leading to session cookie theft or unauthorized actions performed on their behalf.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, deploy SourceCodester Inventory System 1.0 locally and log in as an administrator. Then, access the view_category.php file while including a crafted 'limit' parameter that contains the malicious script payload. Once the page loads, the injected script will execute, demonstrating the cross-site scripting vulnerability.
