What is CVE-2020-25757?

A security flaw in Lua CGIs on D-Link DSR VPN routers exposes the devices to potential remote command execution. The vulnerability stems from inadequate input validation and insufficient access controls, which could allow attackers to send arbitrary commands to system APIs.
