Zxyel Routers Beware

This week we've released a module written by first time community contributor shr70 that can exploit roughly 45 different Zyxel router and VPN models. The module exploits a buffer overflow vulnerability that results in unauthenticated remote code execution on affected devices. It's rare we see a module affect this many devices once and are excited to see this ship in the framework. We hope pentesters and red-teamers alike can make good use of this module in their day to day operations.

Monitorr unauthenticated RCE

Community contributor h00die-gr3y strikes again this time with a module for an Unauthenticated RCE vulnerability in Monitorr. Monitorr is a simple web application that allows you to set up a dashboard to monitor various web sites / web applications up or down state. Vulnerable versions allow an attacker to upload a webshell tagged as a GIF image and execute malicious php code in the upload directory where the malicious file is stored.

More Metasploit Twitch Streaming

In case you missed it or were previously unaware, our very own Spencer McIntyre has been doing live exploit development on Twitch the second Friday of the month at 4pm EST. This past week Spencer (aka zerosteiner) shared in real time the trials and tribulations of reverse engineering an authenticated SolarWinds information service deserialization RCE. The pull request for this work can be found here: In the live stream he explained how he takes a blog posted with limited technical details, decompiles and debugs the application to figure out what makes the vulnerability tick. Come watch the next on Friday April 14th, at:, there's a good chance you'll learn something new and be sure to invite your family and friends!
