      "value": "Froxlor is open source server administration software. Prior to 2.3.8, DNS TXT record content accepted by lib/Froxlor/Api/Commands/DomainZones.php can contain HTML special characters, lib/Froxlor/UI/Callbacks/Text.php returns the content from Text::wordwrap without HTML escaping, and templates/Froxlor/table/table.html.twig renders the callback result with the raw filter. An authenticated customer with DNS editor access can store JavaScript-bearing content in a TXT record. When an administrator views the affected domain's DNS configuration, the payload executes automatically in the administrator's browser session, which can expose session data or perform privileged panel actions. This issue is fixed in version 2.3.8."

Antes de la versión 2.3.8, el contenido de los registros DNS TXT aceptado por lib/Froxlor/Api/Commands/DomainZones.php puede contener caracteres especiales HTML, lib/Froxlor/UI/Callbacks/Text.php devuelve el contenido de Text::wordwrap sin escape HTML, y templates/Froxlor/table/table.html.twig renderiza el resultado de la llamada con el filtro raw. Un cliente autenticado con acceso de editor de DNS puede almacenar contenido que contiene JavaScript en un registro TXT. Cuando un administrador ve la configuración DNS del dominio afectado, la carga útil se ejecuta automáticamente en la sesión del navegador del administrador, lo que puede exponer datos de sesión o realizar acciones privilegiadas del panel. Este problema está solucionado en la versión 2.3.8."
