Technical details

This is a command injection vulnerability in the /boafrm/formIMEISetup interface of the D-Link DWR-M961 router (hardware revision C1). The IMEI_value parameter fails to properly sanitize user input before passing it to a system command, allowing an attacker to inject arbitrary shell metacharacters and execute commands with root privileges. The vulnerability is network-reachable via the device's web-management interface; no authentication is explicitly mentioned as a requirement. An attacker can achieve arbitrary code execution as root on the device. The vulnerability is resolved in firmware version 1.1.5_C1_202607071108 and later.
