Cross-site Scripting occurrences in Transposh Wordpress Translation
The Transposh WordPress Translation WordPress plugin before 1.0.8 does not have CSRF check in its tp_translation AJAX action, which could allow attackers to make authorised users add a translation. Given the lack of sanitisation in the tk0 parameter, this could lead to a Stored Cross-Site Scripting issue which will be executed in the context of a logged in admin (2022-08-22, CVE-2021-24912)
The Transposh WordPress Translation WordPress plugin before 1.0.8 does not sanitise and escape the a parameter via an AJAX action (available to both unauthenticated and authenticated users when the curl library is installed) before outputting it back in the response, leading to a Reflected Cross-Site Scripting issue (2022-08-22, CVE-2021-24910)
The Transposh WordPress Translation WordPress plugin before 1.0.8 does not sanitise and escape the tk0 parameter from the tp_translation AJAX action, leading to Stored Cross-Site Scripting, which will trigger in the admin dashboard of the plugin. The minimum role needed to perform such attack depends on the plugin "Who can translate ?" setting. (2022-08-22, CVE-2021-24911)
Why Cross-site Scripting can be dangerous
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>
