Background
Fork CMS is an open-source content management system (CMS) developed by the Fork CMS community. It provides a user-friendly interface for managing website content and includes various features such as multi-language support, SEO optimization, and customizable templates. However, Fork CMS versions before 3.2.5 are vulnerable to a cross-site scripting (XSS) attack through the highlight parameter in the backend/core/engine/base.php file. This vulnerability allows remote attackers to inject arbitrary web script or HTML, potentially leading to unauthorized access, data theft, or other malicious activities.
Vulnerability Detail
The XSS vulnerability in Fork CMS arises due to insufficient input sanitization in the highlight parameter. Attackers can exploit this by injecting malicious code or HTML into the parameter, which is then rendered on the affected page. This can trick users into executing unintended actions or disclosing sensitive information. The vulnerability has a moderate severity rating and is classified under CWE-79 (Cross-Site Scripting).

Workaround
If upgrading to the latest version is not immediately feasible, a temporary workaround is to manually sanitize the highlight parameter before using it in the affected code. This can be achieved by applying appropriate input validation and escaping techniques, such as HTML entity encoding or using a dedicated HTML sanitization library. Here's an example of how to sanitize the highlight parameter using PHP's htmlspecialchars function:
$highlight = htmlspecialchars($_GET['highlight'], ENT_QUOTES, 'UTF-8');
Conclusion
The XSS vulnerability in Fork CMS versions before 3.2.5 can allow remote attackers to inject arbitrary web script or HTML through the highlight parameter. To mitigate this vulnerability, it is crucial to upgrade to the latest version of Fork CMS (3.2.5 or later) or apply appropriate input sanitization techniques.
