Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

MajorDoMo是MajorDoMo社区的一个开源DIY智能家居自动化平台。 MajorDoMo存在代码注入漏洞，该漏洞源于modules/panel.class.php中的包含顺序错误导致执行在缺少exit语句的redirect()调用后继续，允许未经验证的请求到达inc_panel_ajax.php中的ajax处理程序，该处理程序将来自GET参数的用户输入直接传递给eval()，可能导致远程代码执行。

Vulnerability Title
MajorDoMo Unauthenticated Remote Code Execution via Admin Console Eval
Source: CVE Program / CVE List V5
Vulnerability 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.
