🌙🦊=XSS

DalFox is an powerful open source XSS scanning tool and parameter analyzer and utility that fast the process of detecting and verify XSS flaws. It comes with a powerful testing engine, many niche features for the cool hacker!

I talk about naming. Dal(달) is the Korean pronunciation of moon, and Fox are made to mean "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 Dictonary attack (default is GF-Patterns) - Support custom dictonary 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)
	Optimizaion query of payloads	- Check the injection point through abstraction and generated the fit payload. - Eliminate unnecessary payloads based on badchar
	Encoder	- All test payloads(build-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 - gitub package of docker
	Other	- github action

And the various options required for the testing :D

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	BLANK	PoC Code

• Type: G(Grep) , R(Reflected) , V(Verify)
• Informatin: 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
