Dalfox XSS Tool
DalFox is an powerful automated 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 that can help you while perfoming bug bounty hunt.
This tool can automated analyze single or multiple websites to find XSS vulnerabilities such as Reflected XSS, Stored XSS or even DOM XSS.
I talk about naming. Dal(달) is the Korean pronunciation of moon, and Fox are made to mean “Finder Of XSS”.
Key features
Mode:
- url : Use single target URL mode
- file : Use file mode(targets list or rawdata)
- payload : Payload mode, make and enum payloads
- pipe : Use pipeline mode
- server : Start API Server
- sxss : Use Stored XSS mode
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 ) | |
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 XSS testing.
