CVE-2023-39513: Stored Cross-site Scripting on host.php verbose data-query debug view in Cacti

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 host.php is used to monitor and manage hosts in the cacti app, hence displays useful information such as data queries and verbose logs. CENSUS found that an adversary that is able to configure a data-query template with malicious code appended in the template path, in order to deploy a stored XSS attack against any user with the General Administration>Sites/Devices/Data privileges. A user that possesses the Template Editor>Data Queries permissions can configure the data query template path in cacti. Please note that such a user may be a low privileged user. This configuration occurs through http://<HOST>/cacti/dataqueries.php by editing an existing or adding a new data query template. If a template is linked to a device then the formatted template path will be rendered in the device's management page, when a verbose data query is requested. This vulnerability has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to update should manually filter HTML output.
