CVE-2023-39512

Summary

CVE-2023-39512 is a stored Cross-Site-Scripting (XSS) vulnerability affecting versions of Cacti, an open-source operational monitoring framework. An authenticated user can exploit this weakness by poisoning data in the _cacti_ database and execute JavaScript code in a victim's browser during runtime. The affected component is `data_sources.php`, which displays data source management information, including device names. Malicious device names can be configured by a user with the appropriate permissions, enabling a stored XSS attack against users sharing the same or broader privileges. To mitigate the risk, users are advised to upgrade to version 1.2.25, or manually filter HTML output for those unable to update.
