CVE-2023-39511

Description

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 reports_admin.php displays reporting information about graphs, devices, data sources etc. CENSUS found that an adversary that is able to configure a malicious device name, related to a graph attached to a report, can deploy a stored XSS attack against any super user who has privileges of viewing the reports_admin.php page, such as administrative accounts. 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/reports_admin.php when the a graph with the maliciously altered device name is linked to the report. This issue has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to upgrade should manually filter HTML output.
