DalFox is a fast, powerful parameter analysis and XSS scanner, based on a golang/DOM parser. supports friendly Pipeline, CI/CD and testing of different types of XSS. I talk about naming. Dal(달) is the Korean pronunciation of moon and fox was made into Fox(Find Of XSS).
Mode: url sxss pipe file server
| 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 |
|
| Parameter Mining | - Find new param with Dictonary attack (default is GF-Patterns) - Support custom dictonary file ( --mining-dict-word)- FInd new param with DOM |
|
| Built-in Grepping | - It Identify the basic info leak of SSTi, Credential, SQL Error, and so on | |
| Scanning | XSS Scanning | - Reflected xss / stored xss - DOM 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) |
| 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) |
|
| Extensibility | REST API | - API Server and Swagger (dalfox server) |
| 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) |
|
| Package | Package manager | - homebrew with tap - snapcraft |
| Docker ENV | - docker hub - gitub package of docker |
And the various options required for the testing :D

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
