Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A lack of input validation and access controls in Lua CGIs on D-Link DSR VPN routers may result in arbitrary input being passed to system command APIs, resulting in arbitrary command execution with root privileges. This affects DSR-150, DSR-250, DSR-500, and DSR-1000AC with firmware 3.14 and 3.17.
