CVE-2023-39514

Date: September 5, 2023

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 "graphs.php" displays graph details such as data-source paths, data template information and graph related fields. CENSUS found that an adversary that is able to configure either a data-source template with malicious code appended in the data-source name or a device with a malicious payload injected in the device name, may deploy a stored XSS attack against any user with General Administration>Graphs privileges. A user that possesses the Template Editor>Data Templates permissions can configure the data-source name in cacti. Please note that this may be a low privileged user. This configuration occurs through "http://<HOST>/cacti/data_templates.php"; by editing an existing or adding a new data template. If a template is linked to a graph then the formatted template name will be rendered in the graph's management page. A user that possesses the General Administration>Sites/Devices/Data permissions can configure the device name in cacti. This vulnerability has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to upgrade should add manual HTML escaping.
