Descriptions

Cacti is an open source operational monitoring and fault management framework. Affected versions are subject to a Stored Cross-Site-Scripting (XSS) Vulnerability which allows an authenticated user to poison data stored in the _cacti_'s database. These data will be viewed by administrative _cacti_ accounts and execute JavaScript code in the victim's browser at view-time. The script under `data_sources.php` displays the data source management information (e.g. data source path, polling configuration, device name related to the datasource etc.) for different data visualizations of the _cacti_ app. _CENSUS_ found that an adversary that is able to configure a malicious device name, can deploy a stored XSS attack against any user of the same (or broader) privileges. A user that possesses the _General Administration>Sites/Devices/Data_ permissions can configure the device names in _cacti_. This configuration occurs through `http://<HOST>/cacti/host.php`, while the rendered malicious payload is exhibited at `http://<HOST>/cacti/data_sources.php`. This vulnerability has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to update should manually filter HTML output.

Cacti es un framework de monitorización operativo y gestión de fallos de código abierto. Las versiones afectadas están sujetas a una vulnerabilidad de Cross-Site Scripting (XSS) almacenado que permite a un usuario autenticado envenenar los datos almacenados en la base de datos de _cacti_. Estos datos serán vistos por las cuentas administrativas de _cacti_ y ejecutarán código JavaScript en el navegador de la víctima en tiempo de visualización. El script bajo "data_sources.php" muestra la información de gestión de la fuente de datos (por ejemplo, ruta de la fuente de datos, configuración de sondeo, nombre del dispositivo relacionado con la fuente de datos, etc.) para diferentes visualizaciones de datos de la aplicación _cacti_. _CENSUS_ descubrió que un adversario que es capaz de configurar un nombre de dispositivo malicioso, puede desplegar un ataque de XSS almacenado contra cualquier usuario con los mismos privilegios (o más amplios). Un usuario que posea los permisos de _Administración General - Sitios/Dispositivos/Datos_ puede configurar los nombres de los dispositivos en _cacti_. Esta configuración se produce a través de "http:///cacti/host.php", mientras que el payload malicioso renderizado se exhibe en "http:///cacti/data_sources.php". Esta vulnerabilidad se ha solucionado en la versión 1.2.25. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deberán filtrar manualmente la salida HTML.
