The purpose of this project is to develop scripts that can be useful in the pentesting workflow, be it for VulnHub VMs, CTFs, hands-on certificates, or real-world targets.
The project currently consists of two major components: a script invoking and aggregating the results of existing tools, and a second script for automated analysis of the aforementioned results from the perspective of exploitability.
In terms of real-world pentesting, these scripts are not meant to replace commercial tools such as Nessus or Nexpose, but they can complement it nicely for finding the latest vulnerabilities and their PoC exploits.
The recon.py script runs various open-source tools in order to enumerate the services on a host. Best run under Kali Linux or similar pentesting-oriented distribution with these tools preinstalled and preconfigured.
The flow followed by the script is as follows:
vulnscan.pyResults will be dumped into the results/$ip_address directory, with the $port_$service_$tool file naming scheme. The tools are mostly run simultaneously (unless one depends on the result of another) and the CLI output will be aggregated and tagged by the script, so you will see the progress and dirt found by each running script in real-time.
This script is inspired by Mike Czumak's Recon Scan, which he wrote during his OSCP exam. Many modifications can be found on GitHub, however, I wanted to write a script from scratch, familiarizing myself with each tool and their parameterization, instead of just reusing a bunch of scripts found scattered in various repositories, leaving me none the wiser.

The vulnscan.py script analyses a specified CPE name to determine whether it has any known vulnerabilities and published exploits.
As input, it takes a CPE name, a full name and version, or a path to an xml-based nmap report, which was generated with service detection. When not providing a CPE name, the free-text provided will be fuzzy-matched with the CPE dictionary to check if the provided software name and version has a CPE name. When an nmap report is provided, the CPE names for the identified services are used for the lookup. If the software name and version is available, but the CPE name is not, it will try to fuzzy-match it.
Based on my previous experiences, directly looking up the affected software entries in the CVE database does not always yield the most accurate results, as a software might have multiple CPE names, all referring to the same software. For example, nginx might be listed as cpe:/a:nginx:nginx or cpe:/a:igor_sysoev:nginx, and on the more extreme side, X11 has 12 CPE aliases. In order to combat this, a CPE alias list is used, which is provided and maintained by the Debian Security team, and all aliases are looked up for a given CPE name. Using this technique tends to generate much better results.
Vulnerabilites are listed and color-coded based on availability:
In order to take it one step further, the ExploitDB and SecurityFocus references are extracted from the CVE entries, which allows the script to provide direct links to the exploits. In order to provide perfect ExploitDB and SecurityFocus results for the vulnerabilities, curated lists will have to be used during database updates. If these lists are missing, ExploitDB and SecurityFocus links will still be displayed, but with issues: the SecurityFocus IDs are listed, but information is not available in the CVE entries themselves on whether the SecurityFocus exploit page has any content or not; similarly, the ExploitDB references seem to be missing quite a few entries.
The curated list for ExploitDB will act as a supplemental EDB-CVE map to the ones found in the CVE references. The SecurityFocus list is a list of SecurityFocus IDs with exploit entries, and this list will be used to determine whether a SecurityFocus CVE reference will be imported or not.
The following exploit databases are currently supported, with provided curated lists:
nvd/exploitdb.lstnvd/securityfocus.lstnvd/metasploit.lstnvd/1337day.lstThe idea for this comes from my other open-source project, Host Scanner, which does exactly this, but is written in C++ and is focused more towards security researchers and system administrators, as opposed to CTF players.
The C++ version has a slightly different feature set compared to this Python version: while the main goal of the Python version is to parse nmap reports and end up at exploit links, the C++ version has its own active and passive network scanner, service identifier, and researcher-oriented features, such as non-intrusive vulnerability validation through package manager changelog reports.
