#
#
# FaceSentry Access Control System 6.4.8 Remote Root Exploit
#
#
# Vendor: iWT Ltd.
# Product web page: http://www.iwt.com.hk
# Affected version: Firmware 6.4.8 build 264 (Algorithm A16)
#                   Firmware 5.7.2 build 568 (Algorithm A14)
#                   Firmware 5.7.0 build 539 (Algorithm A14)
#
# Summary: FaceSentry 5AN is a revolutionary smart identity
# management appliance that offers entry via biometric face
# identification, contactless smart card, staff ID, or QR-code.
# The QR-code upgrade allows you to share an eKey with guests
# while you're away from your Office and monitor all activity
# via the web administration tool. 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:    }
# ==============================================================
