Cross Site "Scripter" is an automatic -framework- to detect, exploit and
report XSS vulnerabilities in web-based applications.

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -s, --statistics      show advanced statistics output results
  -v, --verbose         active verbose mode output results
  --gtk                 launch XSSer GTK Interface
  --wizard              start Wizard Helper!

  *Special Features*:
    You can set Vector(s) and Bypasser(s) to build complex scripts for XSS
    code embedded. XST allows you to discover if target is vulnerable to
    'Cross Site Tracing' [CAPEC-107]:

    --imx=IMX           IMX - Create an image with XSS (--imx image.png)
    --fla=FLASH         FLA - Create a flash movie with XSS (--fla movie.swf)
    --xst=XST           XST - Cross Site Tracing (--xst http(s)://host.com)

  *Select Target(s)*:
    At least one of these options must to be specified to set the source
    to get target(s) urls from:

    --all=TARGET        Automatically audit an entire target
    -u URL, --url=URL   Enter target to audit
    -i READFILE         Read target(s) urls from file
    -d DORK             Search target(s) using a query (ex: 'news.php?id=')
    -l                  Search from a list of 'dorks'
    --De=DORK_ENGINE    Use this search engine (default: DuckDuckGo)
    --Da                Search massively using all search engines

  *Select type of HTTP/HTTPS Connection(s)*:
    These options can be used to specify which parameter(s) we want to use
    as payload(s). Set 'XSS' as keyword on the place(s) that you want to
    inject:

    -g GETDATA          Send payload using GET (ex: '/menu.php?id=XSS')
    -p POSTDATA         Send payload using POST (ex: 'foo=1&bar=XSS')
    -c CRAWLING         Number of urls to crawl on target(s): 1-99999
    --Cw=CRAWLER_WIDTH  Deeping level of crawler: 1-5 (default: 2)
    --Cl                Crawl only local target(s) urls (default: FALSE)

  *Configure Request(s)*:
    These options can be used to specify how to connect to the target(s)
    payload(s). You can choose multiple:

    --head              Send a HEAD request before start a test
    --cookie=COOKIE     Change your HTTP Cookie header
    --drop-cookie       Ignore Set-Cookie header from response
    --user-agent=AGENT  Change your HTTP User-Agent header (default: SPOOFED)
    --referer=REFERER   Use another HTTP Referer header (default: NONE)
    --xforw             Set your HTTP X-Forwarded-For with random IP values
    --xclient           Set your HTTP X-Client-IP with random IP values
    --headers=HEADERS   Extra HTTP headers newline separated
    --auth-type=ATYPE   HTTP Authentication type (Basic, Digest, GSS or NTLM)
    --auth-cred=ACRED   HTTP Authentication credentials (name:password)
    --check-tor         Check to see if Tor is used properly
    --proxy=PROXY       Use proxy server (tor: http://localhost:8118)

    --follow-redirects  Follow server redirection responses (302)
    --follow-limit=FLI  Set limit for redirection requests (default: 50)

  *Checker Systems*:
    These options are useful to know if your target is using filters
    against XSS attacks:

    --hash              Send a hash to check if target is repeating content
    --heuristic         Discover parameters filtered by using heuristics
    --discode=DISCODE   Set code on reply to discard an injection
    --checkaturl=ALT    Check reply using: <alternative url> [aka BLIND-XSS]
    --checkmethod=ALTM  Check reply using: GET or POST (default: GET)
    --checkatdata=ALD   Check reply using: <alternative payload>
    --reverse-check     Establish a reverse connection from target to XSSer

  *Select Vector(s)*:
    These options can be used to specify injection(s) code. Important if
    you don't want to inject a common XSS vector used by default. Choose
    only one option:

    --payload=SCRIPT    OWN   - Inject your own code
    --auto              AUTO  - Inject a list of vectors provided by XSSer

    --auto-info         AINFO - Select ONLY vectors with INFO (default: FALSE)
    --auto-random       ARAND - Set random to order (default: FALSE)

    --Phpids0.7         PHPIDS (0.7) [ALL]

    --Iexplorer         IExplorer 9 & Firefox 12 [& below]

  *Select Bypasser(s)*:
    These options can be used to encode vector(s) and try to bypass
    possible anti-XSS filters. They can be combined with other techniques:

    --Str               Use method String.FromCharCode()
    --Une               Use Unescape() function

    --Doo               Encode IP addresses with Octal
    --Cem=CEM           Set different 'Character Encoding Mutations'
                        (reversing obfuscators) (ex: 'Mix,Une,Str,Hex')

  *Special Technique(s)*:
    These options can be used to inject code using different XSS
    techniques and fuzzing vectors. You can choose multiple:

    --Coo               COO - Cross Site Scripting Cookie injection
    --Xsa               XSA - Cross Site Agent Scripting
    --Xsr               XSR - Cross Site Referer Scripting
    --Dcp               DCP - Data Control Protocol injections
    --Dom               DOM - Document Object Model injections
    --Ind               IND - HTTP Response Splitting Induced code

  *Select Final injection(s)*:
    These options can be used to specify the final code to inject on
    vulnerable target(s). Important if you want to exploit 'on-the-wild'
    the vulnerabilities found. Choose only one option:

    --Fp=FINALPAYLOAD   OWN    - Exploit your own code
    --Fr=FINALREMOTE    REMOTE - Exploit a script -remotely-

  *Special Final injection(s)*:
    These options can be used to execute some 'special' injection(s) on
    vulnerable target(s). You can select multiple and combine them with
    your final code (except with DCP exploits):

    --Anchor            ANC  - Use 'Anchor Stealth' payloader (DOM shadows!)
    --B64               B64  - Base64 code encoding in META tag (rfc2397)
    --Onm               ONM  - Use onMouseMove() event
    --Ifr               IFR  - Use <iframe> source tag
    --Dos               DOS  - XSS (client) Denial of Service
    --Doss              DOSs - XSS (server) Denial of Service

  *Reporting*:
    --save              Export to file (XSSreport.raw)
    --xml=FILEXML       Export to XML (--xml file.xml)

  *Miscellaneous*:
    --silent            Inhibit console output results
    --alive=ISALIVE     Set limit of errors before check if target is alive
    --update            Check for latest stable version

----------------------------------------

* Apply Anti-antiXSS bypassers (ex: Imperva) before to inject you -own- code with verbose output:
