Technical details
The vulnerability is a command injection flaw in the /boafrm/formL2tpv3ConfigSetup endpoint of the D-Link DWR-M961 web-management CGI. The tunnelid and sessionid input parameters are not properly sanitized before being passed to shell commands, allowing an unauthenticated or low-privilege attacker to inject arbitrary shell metacharacters. No authentication is required to access the vulnerable endpoint. Successful exploitation results in command execution with root privileges. The vulnerability was resolved in firmware version 1.1.5_C1_202607071108 and later.
