CVE-2023-39516

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
etc.) for different data visualizations of the cacti app. CENSUS found
that an adversary that is able to configure a malicious data-source path,
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 data
source path in Cacti. This configuration occurs through
http://<HOST>/cacti/data_sources.php. The same page can be used for
previewing the data source path. This issue has been addressed in version
1.2.25. Users are advised to upgrade. Users unable to upgrade should
manually escape HTML output.
