Read Me
Cross Site "Scripter" (aka XSSer) is an automatic -framework- to detect, exploit and report XSS vulnerabilities in web-based applications.
It provides several options to try to bypass certain filters and various special techniques for code injection.
Key features:
- [ > 1500 ] pre-installed XSS attacking vectors (automatic fuzzing).
- Validation: each finding is verified for real executability. A context-aware engine tells apart executable contexts (HTML, JS, event handlers, javascript:/data: URIs) from harmless reflections, with an optional headless-browser reverse connection (--reverse-check) to confirm findings and cut false positives.
- Targeting: URL, file, stdin/pipe, raw HTTP request (-r), 'dorking' (multiple engines) and crawler.
- Injection: GET/POST, Cookie/User-Agent/Referer, DOM and HTTP Response Splitting.
- Evasion: per-WAF bypassers + character-encoding bypassers; proxy/Tor; client-certificate auth.
- Reporting: PDF (professional), XML and JSON (for CI / pipelines).
It can also bypass-exploit code on several WAFs:
[Cloudflare]: Cloudflare WAF
[Akamai]: Akamai (Kona / App & API Protector)
[AWS]: AWS WAF
[Azure]: Azure Front Door WAF
[Imperva]: Imperva (Incapsula / Cloud WAF)
[F5]: F5 BIG-IP ASM / Advanced WAF
[Barracuda]: Barracuda WAF
[ModSec]: Mod-Security + OWASP CRS v3
[Wordfence]: Wordfence (WordPress)
[Sucuri]: Sucuri (CloudProxy)
[FortiWeb]: Fortinet FortiWeb
[WebKnight]: AQTRONIX WebKnight
Installing:
XSSer runs on many platforms. It requires Python (>=3.9).
Only two libraries are mandatory (the core HTTP engine and the HTML parser):
- pycurl - Python bindings to libcurl
- beautifulsoup4 - error-tolerant HTML parser
The rest are optional and only needed for a specific feature. If missing, XSSer
can auto-install them on demand (pip) the first time the feature is used, except
on 'externally-managed' (PEP 668) Python environments, where it prints the manual
install command instead (set XSSER_AUTOINSTALL=1 to override):
- fpdf2 - '--pdf' report exporter [extra: pdf]
- ddgs - 'dorking' engine ('-d' / '-l') [extra: dork]
- selenium - DOM / reverse-check browser ('--Dom') [extra: dom]
- PyGObject + pycairo + pygeoip + Pillow - GTK GUI + GeoMap ('--gtk') [extra: gtk]
Install (from the source tree), core only or with the extras you want:
pip3 install . # mandatory libs only
pip3 install .[pdf] # + PDF reporting
pip3 install .[full] # everything (all optional features)
On Debian-based systems (ex: Kali, Ubuntu, ParrotSec) the same libs are also
packaged. The distro package name differs from the pip name; the mapping is:
pip name Debian/Ubuntu/Kali package
------------ --------------------------
beautifulsoup4 python3-bs4
pycurl python3-pycurl
fpdf2 python3-fpdf2
selenium python3-selenium
PyGObject python3-gi
pycairo python3-cairo (+ python3-gi-cairo for GTK integration)
Pillow python3-pil
pygeoip python3-geoip
(ddgs has no distro package yet: install it with pip)
# mandatory:
sudo apt-get install python3-pycurl python3-bs4
# optional (per feature you want to enable):
sudo apt-get install python3-fpdf2 python3-selenium python3-gi python3-gi-cairo python3-cairo python3-pil python3-geoip
Note: some optional features also need system-level (non-pip) components:
- '--Dom' / '--reverse-check' : firefox + geckodriver (the Firefox WebDriver).
- '--gtk' : GTK 3 plus its GObject-Introspection typelib
files (the .typelib for Gtk-3.0). That typelib
ships under different system package names per
distro, e.g. 'gir1.2-gtk-3.0' on Debian/Ubuntu/
Kali, and 'gtk3' on Fedora/Arch.
