Description
HAX CMS PHP allows users to manage their microsite universe with a PHP backend. Prior to version 11.0.0, the application does not sufficiently sanitize user input, allowing for the execution of arbitrary JavaScript code. The 'saveNode' and 'saveManifest' endpoints take user input and store it in the JSON schema for the site. This content is then rendered in the generated HAX site. Although the application does not allow users to supply a `script` tag, it does allow the use of other HTML tags to run JavaScript. Version 11.0.0 fixes the issue.

How can this vulnerability impact me? :

This vulnerability can lead to the execution of arbitrary JavaScript code in the context of the affected site, potentially allowing attackers to steal sensitive information, hijack user sessions, perform actions on behalf of users, or deface the site. Because the vulnerability allows cross-site scripting, it can compromise the confidentiality and integrity of user data and the application.


What immediate steps should I take to mitigate this vulnerability?

Upgrade HAX CMS to version 11.0.0 or later, as this version fixes the issue by properly sanitizing user input to prevent arbitrary JavaScript execution.


Can you explain this vulnerability to me?

This vulnerability in HAX CMS PHP prior to version 11.0.0 allows attackers to execute arbitrary JavaScript code because the application does not sufficiently sanitize user input. Specifically, the 'saveNode' and 'saveManifest' endpoints accept user input that is stored in the site's JSON schema and later rendered in the generated site. While the application blocks the use of <script> tags, it permits other HTML tags that can run JavaScript, leading to cross-site scripting (XSS) attacks. Version 11.0.0 fixes this issue.
