## Technical details

Multiple command injection vulnerabilities exist in the web-management CGI components of the DWR-M961, affecting parameters in diagnostic functions (ping, traceroute, debug), FOTA upgrade handlers, SMS management, USSD setup, and other interfaces. The vulnerable endpoints include /boafrm/formPingDiagnosticRun, /boafrm/formTracerouteDiagnosticRun, /boafrm/formDebugDiagnosticRun, and others that fail to properly sanitize user input before passing it to system commands. Remote attackers can inject malicious shell commands (e.g., via the host field in ping diagnostics) to achieve arbitrary code execution with root privileges; no authentication is explicitly required based on the advisory. The vulnerabilities were resolved in firmware version 1.1.5_C1_202607071108 and later.
