What it is

⚠️ A crafty command execution vulnerability hides in the TOTOLINK T6 — it’s like finding a secret backdoor in a supposedly secure building! 🏢 Imagine a maintenance worker who can wander through a building without anyone checking their ID — that’s how an attacker could run any command they wish through cstecgi.cgi without proper authorization. It’s a surprisingly sneaky oversight! An attacker could exploit this flaw to execute arbitrary commands on the router, potentially compromising the entire network. This could lead to unauthorized access, data breaches, or even network manipulation — all without needing valid credentials. Yikes!
