Netgear Wnr2000v5 Vulnerabilities & CVEs

Q: Is my Netgear Wnr2000v5 affected by these vulnerabilities?

Only if you’re running a firmware version in the affected range listed above and haven’t updated. Check your router's admin panel for its current firmware version and compare it against the ranges below.

Q: How do I update my Netgear Wnr2000v5's firmware?

Log into the router's web admin panel (usually at its local IP address) and look for a Firmware Update or System Update section, or use the vendor's mobile app if it has one.

Q: Does ProbeShield fix these vulnerabilities for me?

No — ProbeShield scans your network and tells you what it finds (open ports, default credentials, outdated firmware signals) so you know what to fix, and how. It never changes your devices’ settings.

Commonly exposed ports

Port 23 (Telnet) — Sends admin credentials unencrypted — a common target on older router firmware.
Port 80 (HTTP admin panel) — The web admin UI; dangerous if remote/WAN administration is left enabled.
Port 7547 (TR-069 (CWMP)) — ISP remote-management protocol — has been the entry point for several router botnets.
Port 1900 (UPnP/SSDP) — Lets apps on your LAN open firewall holes automatically, sometimes without your knowledge.

Default credentials

From ProbeShield's own tested default-credential list (see probeshield.com/default-passwords/): "netgear" / "password" or "admin" / "netgear1" or "admin" / "password123" over HTTP.

Hardening checklist

Disable remote (WAN-side) administration unless you specifically need it.
Turn off UPnP unless a specific app you trust requires it.
Turn off WPS — it can let an attacker bypass your Wi-Fi password.
Change the default admin username and password to something unique.
Check for a firmware update in the router’s admin panel and apply it.
Disable Telnet/SSH management access if you don’t actively use it.
