![]() This article is a bit of a divergence for me, I recently had the need to scan an entire network for a particularly nasty Microsoft security vulnerability MS15-034 ↗. There are a few ways to check for this, the first is obvious, check what servers have IIS installed. However, this bug isn’t limited to IIS, rather anything using HTTP.sys and, of course, a HTTP server can be spun up on any port you want so we need to check for servers that have HTTP exposed on any port from 1-65535. Nobody wants to manually log on to every server and check if the specific KB patch ↗ is installed though, that takes a lot of effort and time. So is there a way we can scan for vulnerabilities in a “start and forget” sort of way? ZENMAP NSE PATCH Sure, we can use Zenmap ↗ - Zenmap is a GUI built on top of nmap, a network scanner that can gather info on open ports, OS detection, etc. It has tons of really cool features, but one thing it allows for that is of particular benefit is scripting of particular scan parameters, this makes it ideal for vulnerability scanning. ![]() This is possible through the Nmap Scripting Engine (NSE), Nmap's most powerful feature that gives its users the ability to write their own scripts and use Nmap for more than just. The reason I use Zenmap is that it provides a nice summarised output of nmap commands and supports all of the features nmap does. Nmap is not only the best port-scanning tool out there, but also a very good service-level enumeration tool with support for customized scripts and hundreds of publicly available scripts ready to use out of the box.
