Nagios XI < 2024R1.1.4 Authenticated Local File Inclusion via NagVis
Nagios XI versions prior to 2024R1.1.4 contain a local file inclusion (LFI) vulnerability via its NagVis integration. An authenticated user can supply crafted path values that cause the server to include local files, potentially exposing sensitive information from the underlying host.
Nagios addresses this vulnerability as "Nagios XI is vulnerable to an authenticated Local File Inclusion attack via Nagvis." and as part of "Fixed both XSS in Executive Summary report and ajaxhelper endpoint that was too open."
