In short
The TP-Link Archer routers (NX200, NX210, NX500, NX600) have a flaw where certain functions skip authentication checks, letting anyone access admin features like firmware uploads and settings changes without logging in.
Technical detail
Missing authentication validation in HTTP CGI endpoints allows unauthenticated remote attackers to execute privileged operations including firmware upload and configuration modifications. Pre-condition: network accessibility to the HTTP server; impact includes complete router compromise and arbitrary code execution.
Summary generated and translated by AI from the official description.
A missing authentication check in the HTTP server on TP-Link Archer NX200, NX210, NX500 and NX600 to certain cgi endpoints allows unauthenticated access intended for authenticated users. An attacker may perform privileged HTTP actions without authentication, including firmware upload and configuration operations.
