Executive Summary

CVE-2025-67683 is a reflected Cross-Site Scripting (XSS) vulnerability in Quick.Cart version 6.7. It occurs via the 'sSort' parameter, where an attacker can craft a malicious URL that, when opened by a victim, executes arbitrary JavaScript code in the victim's browser. This happens because the input is not properly neutralized during web page generation. [1]

Detection Guidance

This vulnerability can be detected by testing the Quick.Cart application, specifically by checking if the sSort parameter in URLs is vulnerable to reflected XSS. You can try crafting a URL with a JavaScript payload in the sSort parameter and observe if the script executes in the browser. For example, you can use curl or a browser to send a request like: curl 'http://your-quickcart-site/?sSort=<script>alert(1)</script>' and check if the script is reflected and executed. There are no specific commands provided in the resources, but manual testing of the sSort parameter with XSS payloads is recommended. [1]

Mitigation Strategies

Immediate mitigation steps include sanitizing and properly encoding the sSort parameter input to prevent execution of arbitrary JavaScript. If possible, apply any available patches or updates from the vendor. Since the vendor did not provide details or affected version ranges and only version 6.7 is confirmed vulnerable, consider restricting access to the affected version or disabling the vulnerable functionality until a fix is available. Additionally, educate users to avoid clicking on suspicious URLs that may exploit this vulnerability. [1]
