DO THIS FIRSTFind out if you use it. If you do, apply the vendor's fix. Not sure if you use it? Send this page to your IT provider or security lead and ask.

TECHNICAL SUMMARY On certain TOTOLINK Realtek SDK based routers, an authenticated attacker may execute arbitrary OS commands via the sysCmd parameter to the boafrm/formSysCmd URI, even if the GUI (syscmd.htm) is not available. This allows for full control over the device's internals.

WHY THIS VERDICT Attack attempts are confirmed, with no confirmed exploitation yet.

WHY IT RANKS HERE Ready-made attack tools are public. The first report is 19 days old.
