CVE-2026-27174
MajorDoMo Unauthenticated Remote Code Execution via Admin Console Eval
Description

MajorDoMo (aka Major Domestic Module) allows unauthenticated remote code execution via the admin panel's PHP console feature. An include order bug in modules/panel.class.php causes execution to continue past a redirect() call that lacks an exit statement, allowing unauthenticated requests to reach the ajax handler in inc_panel_ajax.php. The console handler within that file passes user-supplied input from GET parameters (via register_globals) directly to eval() without any authentication check. An attacker can execute arbitrary PHP code by sending a crafted GET request to /admin.php with ajax_panel, op, and command parameters.
