Description

Command-injection vulnerabilities exist in diag_smart.php and diag_routes.php. These allow authenticated WebGUI users with privileges for diag_smart.php or diag_routes.php to execute commands in the context of the root user. A user on pfSense version 2.3.1 or earlier, granted limited access to the pfSense web configurator GUI including access to diag_smart.php and diag_routes.php via their associated privileges: "WebCfg - Diagnostics: S.M.A.R.T. Status" and "WebCfg - Diagnostics: Routing Tables" respectively, could leverage these vulnerabilities to gain increased privileges, read other files, execute commands, or perform other alterations. This is not relevant for admin-level users as there are other deliberate means by which an administrator could run commands.
