Wikindx Cross-site Scripting

A cross-site scripting (XSS) vulnerability in many forms of Wikindx before 5.7.0 and 6.x through 6.4.0 allows remote attackers to inject arbitrary web script or HTML via the message parameter to index.php?action=initLogon or modules/admin/DELETEIMAGES.php. (2021-02-01, CVE-2021-3340)

A cross-site scripting (XSS) vulnerability in getPagingStart() in core/lists/PAGING.php in WIKINDX before 5.8.2 allows remote attackers to inject arbitrary web script or HTML via the PagingStart parameter. (2019-07-26, CVE-2019-13588)

A cross-site scripting (XSS) vulnerability in noMenu() and noSubMenu() in core/navigation/MENU.php in WIKINDX prior to version 5.8.1 allows remote attackers to inject arbitrary web script or HTML via the method parameter. (2019-07-08, CVE-2019-12930)

A cross-site scripting (XSS) vulnerability in ressource view in core/modules/resource/RESOURCEVIEW.php in Wikindx prior to version 5.7.0 allows remote attackers to inject arbitrary web script or HTML via the id parameter. (2019-03-26, CVE-2019-9961)

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>
