Description

A Local File Include (LFI) vulnerability was discovered in pkg_mgr_install.php, a part of the pfSense WebGUI, via the logfilename parameter. The logfilename parameter on pkg_mgr_install.php in an AJAX request was used to specify a file to read, ending in .txt. This file name was not sanitized or restricted to a specific path. An authenticated user sending a specially crafted POST request could read any file on the filesystem with a name ending in '.txt'.
