GitHub - hahwul/dalfox: 🌙🦊 Dalfox is a powerful open-source XSS scanner and utility focused on automation.

DalFox is a powerful open-source tool that focuses on automation, making it ideal for quickly scanning for XSS flaws and analyzing parameters. Its advanced testing engine and niche features are designed to streamline the process of detecting and verifying vulnerabilities.

As for the name, Dal(달) is the Korean word for "moon," while "Fox" stands for "Finder Of XSS" or 🦊

Key features

Mode: url sxss pipe file server payload

Class	Key Feature	Description
Discovery	Parameter analysis	- Find reflected param - Find alive/bad special chars, event handler and attack code - Identification of injection points(HTML/JS/Attribute) `inHTML-none` `inJS-none` `inJS-double` `inJS-single` `inJS-backtick` `inATTR-none` `inATTR-double` `inATTR-single`
	Static analysis	- Check bad-header like CSP, XFO, etc.. with req/res base
	BAV analysis	- Testing BAV(Basic Another Vulnerability) , e.g `sqli` `ssti` `open-redirects`, `crlf`, `esii`
	Parameter Mining	- Find new param with Dictionary attack (default is GF-Patterns) - Support custom dictionary file (`--mining-dict-word`) - Find new param with DOM - Use remote wordlist to mining (`--remote-wordlists`)
	Built-in Grepping	- It Identify the basic info leak of SSTi, Credential, SQL Error, and so on
	WAF Detection and Evasion	- Detect to WAF(Web Application Firewall). - if found waf and using special flag, evasion using slow request - `--waf-evasion`
Scanning	XSS Scanning	- Reflected XSS / Stored XSS / DOM XSS - DOM base verifying - Headless base verifying - Blind XSS testing with param, header(`-b` , `--blind` options) - Only testing selected parameters (`-p`, `--param`) - Only testing parameter analysis (`--only-discovery`)
	Friendly Pipeline	- Single url mode (`dalfox url`) - From file mode (`dalfox file urls.txt`) - From IO(pipeline) mode (`dalfox pipe`) - From raw http request file mode (`dalfox file raw.txt --rawdata`)
	Optimization query of payloads	- Check the injection point through abstraction and generated the fit payload. - Eliminate unnecessary payloads based on badchar
	Encoder	- All test payloads(built-in, your custom/blind) are tested in parallel with the encoder. - To Double URL Encoder - To HTML Hex Encoder
	Sequence	- Auto-check the special page for stored xss (`--trigger`) - Support (`--sequence`) options for Stored XSS , only `sxss` mode
HTTP	HTTP Options	- Overwrite HTTP Method (`-X`, `--method`) - Follow redirects (`--follow-redirects`) - Add header (`-H`, `--header`) - Add cookie (`-C`, `--cookie`) - Add User-Agent (`--user-agent`) - Set timeout (`--timeout`) - Set Delay (`--delay`) - Set Proxy (`--proxy`) - Set ignore return codes (`--ignore-return`) - Load cookie from raw request (`--cookie-from-raw`)
Concurrency	Worker	- Set worker's number(`-w`, `--worker`)
	N * hosts	- Use multicast mode (`--multicast`) , only `file` / `pipe` mode
Output	Output	- Only the PoC code and useful information is write as Stdout - Save output (`-o`, `--output`)
	Format	- JSON / Plain (`--format`)
	Printing	- Silence mode (`--silence`) - You may choose not to print the color (`--no-color`) - You may choose not to print the spinner (`--no-spinner`) - You may choose show only special poc code (`--only-poc`)
	Report	- Show detail report (`--report` and `--report-format=<plain/json>`)
Extensibility	REST API	- API Server and Swagger (`dalfox server`)
	Payload Mode	- Generate and Enumerate Payloads for XSS Testing (`dalfox payload`)
	Found Action	- Lets you specify the actions to take when detected. - Notify, for example (`--found-action`)
	Custom Grepping	- Can grep with custom regular expressions on response - If duplicate detection, it performs deduplication (`--grep`)
	Custom Payloads	- Use custom payloads list file (`--custom-payload`) - Custom alert value (`--custom-alert-value`) - Custom alert type (`--custom-alert-type`)
	Remote Payloads	- Use remote payloads from portswigger, payloadbox, etc.. (`--remote-payloads`)
Package	Package manager	- pkg.go.dev - homebrew with tap - snapcraft
	Docker ENV	- docker hub - github package of docker
	Other	- github action

And the various options required for the testing :D

How to Install

Using homebrew (macos)

brew install dalfox

Using snapcraft (ubuntu)

sudo snap install dalfox

From source

go install github.com/hahwul/dalfox/v2@latest

# The actual release might slightly differ. This is because go install references the main branch.

More information? please read Installation guide

Usage

dalfox [mode] [target] [flags]

Single target mode

dalfox url http://testphp.vulnweb.com/listproducts.php\?cat\=123\&artist\=123\&asdf\=ff \
	-b https://your-callback-url

Multiple target mode from file

dalfox file urls_file --custom-payload ./mypayloads.txt

Pipeline mode

POC format

Sample poc log

[POC][G][BUILT-IN/dalfox-error-mysql/GET] http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123DalFox
[POC][V][GET] http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123%22%3E%3Csvg%2Fclass%3D%22dalfox%22onLoad%3Dalert%2845%29%3E

Format

Identity	Type	Information	PoC Code
POC	G	BUILT-IN/dalfox-error-mysql/GET	http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123DalFox
POC	R	GET	http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123%22%3E%3Csvg%2Fclass%3D%22dalfox%22onLoad%3Dalert%2845%29%3E

Type: G(Grep) , R(Reflected) , V(Verify)
Information: Method, grepping name, etc..

Why is there a gap? It is a method to make it easier to parse only the poc code through cut etc. For example, you can do this.

dalfox url http://testphp.vulnweb.com/listproducts.php\?cat\=123\&artist\=123\&asdf\=ff \
	| cut -d " " -f 2 > output
cat output
# http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123DalFox
# http://testphp.vulnweb.com/listproducts.php?artist=123&asdf=ff&cat=123%22%3E%3Csvg%2FOnLoad%3D%22%60%24%7Bprompt%60%60%7D%60%22+class%3Ddalfox%3E

In the code

package main

import (
	"fmt"

	dalfox "github.com/hahwul/dalfox/v2/lib"
)

func main() {
	opt := dalfox.Options{

	result, err := dalfox.NewScan(dalfox.Target{

	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(result)
	}
}

go build -o xssapp ; ./xssapp
