CVE-2020-25757: Input Validation
First published: Tue Dec 15 2020(Updated: )
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.
