CVE-2026-30480 Details
Description
A Local File Inclusion (LFI) vulnerability in the NFSen module (nfsen.inc.php) of LibreNMS 22.11.0-23-gd091788f2 allows authenticated attackers to include arbitrary PHP files from the server filesystem via path traversal sequences in the nfsen parameter.
A Local File Inclusion (LFI) vulnerability has been identified in the NFSen module of LibreNMS versions 22.11.0-23-gd091788f2. This vulnerability allows authenticated attackers to include arbitrary PHP files from the server filesystem by exploiting path traversal sequences in the 'nfsen' parameter. The issue arises because user input is directly concatenated into the 'include()' statement without proper sanitization, and the only validation performed is a file existence check that does not prevent path traversal.
It is recommended to implement whitelist-based validation for the 'nfsen' parameter or to use the 'basename()' function to strip path traversal characters before including the file.
