## Technical details

The vulnerability is a command injection flaw in the /boafrm/formPingDiagnosticRun web CGI interface of the D-Link DWR-M961. The vulnerable "host" parameter fails to properly sanitize user input before passing it to a system command, allowing an attacker to inject arbitrary shell commands. The vulnerability requires network access to the web management interface (typically port 80 or 8080) but no authentication is explicitly mentioned as a prerequisite in the advisory. Successful exploitation results in arbitrary command execution with root-level privileges. The vulnerability is resolved in firmware version 1.1.5_C1_202607071108 and later.
