PHP-Fusion 9.03.60 allows XSS via the administration/site_links.php Add Site Link field. (2020-06-24, CVE-2020-15041)

In administration/comments.php in PHP-Fusion 9.03.50, an authenticated attacker can take advantage of a stored XSS vulnerability in the Preview Comment feature. The protection mechanism can be bypassed by using HTML event handlers such as ontoggle. (2020-05-08, CVE-2020-12718)

Multiple cross-site scripting vulnerabilities in PHP-Fusion 9.03.50 allow remote attackers to inject arbitrary web script or HTML via the cat_id parameter to downloads/downloads.php or article.php. NOTE: this might overlap CVE-2012-6043. (2020-05-07, CVE-2020-12708)

Multiple Cross-site scripting vulnerabilities in PHP-Fusion 9.03.50 allow remote attackers to inject arbitrary web script or HTML via the go parameter to faq/faq_admin.php or shoutbox_panel/shoutbox_admin.php (2020-05-07, CVE-2020-12706)

An XSS vulnerability exists in the banners.php page of PHP-Fusion 9.03.50. This can be exploited because the only security measure used against XSS is the stripping of SCRIPT tags. A malicious actor can use HTML event handlers to run JavaScript instead of using SCRIPT tags. (2020-04-28, CVE-2020-12438)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
