xssmap

xssmap is a tiny tool to scan for (DOM)XSS vulnerabilities by using a headless browser based on webkit (PhantomJS). This enables evaluation of attack vectors and is nearly false positive free.

Requirements

• PhantomJS (command line tool)

Installation

1. Install the phantomjs command line tool.
2. go get github.com/rverton/xssmap
3. xssmap -h

Usage

XSSMAP v0.1. github.com/rverton/xssmap

Usage:
    xssmap [--method=<method>] [--data=<data>] [--json] [--failed] [--payloads=<payloads.txt>] URL
    xssmap -h | --help
    xssmap --version

Arguments:
    URL  insert {XSS} as a placeholder for payloads

Options:
    --failed  Show failed attempts.
    --json  Use JSON as output format.
    -h --help  Show this screen.
    --version  Show version.

Example:
    xssmap http://server.com/foo{XSS}
    xssmap --method=POST --data="foo={XSS}" http://server.com/vuln
    xssmap --failed http://server.com/foo#{XSS}

Payloads

Payloads are located in payloads.txt. xssmap checks if window.xssmap is defined. All payloads are either

• setting window.xssmap = true; or
• calling xssm(), a function which is injected and executes window.xssmap = true.

Most of payloads were slightly modified from ra2-dom-xss-scanner.
