Technical details

This is a command-injection vulnerability in the /boafrm/formUSSDSetup CGI handler on D-Link DWR-M961 hardware revision C1 devices. The vulnerability exists in two operating modes: the ussdValue field when ussdStatusInput=ussd and the selectMenuValue field when ussdStatusInput=menu. Both fields fail to properly sanitize user input before passing it to shell execution, allowing an attacker to inject arbitrary commands. The vulnerability is reachable over the network via the device's web-management interface; no authentication is required. Successful exploitation results in command execution with root privileges. The issue is resolved in firmware version 1.1.5_C1_202607071108.
