Last updated: October 8, 2017 | 2,941 views

VHostScan is a Python-based virtual host scanner that can be used with pivot tools, detect catch-all scenarios, aliases and dynamic default pages.

VHostScan - Virtual Host Scanner With Alias & Catch-All Detection

Features of VHostScan Virtual Host Scanner

Quickly highlight unique content in catch-all scenarios
Locate the outliers in catch-all scenarios where results have dynamic content on the page (such as the time)
Identify aliases by tweaking the unique depth of matches
Wordlist supports standard words and a variable to input a base hostname (for e.g. dev.%s from the wordlist would be run as dev.BASE_HOST)
Work over HTTP and HTTPS
Ability to set the real port of the webserver to use in headers when pivoting through ssh/nc
Add simple response headers to bypass some WAF products
Identify new targets by using reverse lookups and append to wordlist

Usage – Using VHostScan

-h, --help	Display help message and exit
-t TARGET_HOSTS	Set the target host.
-b BASE_HOST	Set host to be used during substitution in wordlist (default to TARGET).
-w WORDLISTS	Set the wordlist(s) to use. You may specify multiple wordlists in comma delimited format (e.g. -w "./wordlists/simple.txt, ./wordlists/hackthebox.txt" (default ./wordlists/virtual-host-scanning.txt).
-p PORT	Set the port to use (default 80).
-r REAL_PORT	The real port of the web server to use in headers when not 80 (see RFC2616 14.23), useful when pivoting through ssh/nc etc (default to PORT).
--ignore-http-codes IGNORE_HTTP_CODES	Comma-separated list of HTTP codes to ignore with virtual host scans (default 404).
--ignore-content-length IGNORE_CONTENT_LENGTH	Ignore content lengths of specified amount.
--unique-depth UNIQUE_DEPTH	Show likely matches of page content that is found x times (default 1).
--ssl	If set then connections will be made over HTTPS instead of HTTP.
--fuzzy-logic	If set then all unique content replies are compared and a similarity ratio is given for each pair. This helps to isolate vhosts in situations where a default page isn't static (such as having the time on it).
--no-lookups	Disbale reverse lookups (identifies new targets and append to wordlist, on by default).
--rate-limit	Amount of time in seconds to delay between each scan (default 0).
--random-agent	If set, each scan will use a random user-agent from a predefined list.
--user-agent	Specify a user agent to use for scans.
--waf	If set then simple WAF bypass headers will be sent.
-oN OUTPUT_NORMAL	Normal output printed to a file when the -oN option is specified with a filename argument.
-oJ OUTPUT_JSON	JSON output printed to a file when the -oJ option is specified with a filename argument.
-	By passing a blank '-' you tell VHostScan to expect input from stdin (pipe).
