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.
