1. Description

PHP `filter_input()` function with `FILTER_VALIDATE_URL` flag is used to validate url inside `savefaq` functionality.

But this function doesn’t protect against XSS.

2. Proof of Concept

By default every user can propose faq entries.

When admin activate article using http://phpmyfaq/admin/?action=view url or records.defaultActivation option is enabled, XSS will be visible on entry page:

http://phpmyfaq/index.php?action=artikel&cat=%cat_id%&id=%article_id%&artlang=pl

For exploitation use folowing url inside Link for this FAQ field:

http://example.com/"><script>alert("xss")</script>

3. Solution:

Update to version 2.9.1
