Usage of Gxss:
-c int
Set the Concurrency (default 50)
-d string
Request data for POST based reflection testing
-h value
Set Custom Header.
-o string
Save Result to OutputFile
-p string
Payload you want to Send to Check Reflection (default "Gxss")
-u string
Set Custom User agent. Default is Mozilla (default "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36")
-v Verbose mode
-x string
Proxy URL. Example: http://127.0.0.1:8080
-
Checking Single Url
echo "https://target.com/some.php?first=hello&last=world | Gxss -c 100
-
Checking List of Urls
cat urls.txt | Gxss -c 100 -p XssReflected
-
Save Urls Which have Reflecting Params in a file for further analysis
cat urls.txt | Gxss -c 100 -o Result.txt
-
For verbose mode
-v
cat urls.txt | Gxss -c 100 -o Result.txt -v
-
Send Custom Header
-h
cat urls.txt | Gxss -c 100 -p Xss -h "Cookie: Value"
-
Send Custom User-Agent
-u
cat urls.txt | Gxss -c 100 -p Xss -h "Cookie: Value" -u "Google Bot"
- It takes Urls from STDIN
- It check for the reflected value on params one by one. (There are some tool like qsreplace which replace all params value but gxss checks payload one by one which makes it different from all those tools.)
For Example-
Url is https://example.com/?p=first&q=second
First it will check if p param reflects
https://example.com/?p=Gxss&q=second
Then it will check if q param reflects
https://example.com/?p=first&q=Gxss
- If reflection for any param is found it tells which param reflected in response.
echo "testphp.vulnweb.com" | waybackurls | httpx -silent | Gxss -c 100 -p Xss | sort -u | dalfox pipe
