CVE-2023-39510

Summary

CVE-2023-39510 is a stored Cross-Site-Scripting (XSS) vulnerability affecting Cacti, an open-source operational monitoring framework. Affected versions allow authenticated users to inject malicious JavaScript code into the _cacti_ database. This data is then displayed in the `reports_admin.php` script, which is accessible to administrative Cacti accounts. An attacker with the ability to configure a malicious device name can exploit this vulnerability, potentially executing JavaScript code in the victim's browser. Users with "General Administration>Sites/Devices/Data" permissions can configure device names via `http://<HOST>/cacti/host.php`, and the malicious payload is displayed at `http://<HOST>/cacti/reports_admin.php` when a graph with the altered device name is accessed. Version 1.2.25 has addressed this issue, and users are advised to upgrade. Those unable to update should manually filter HTML output.
