Loading vulnerability…
Horde Groupware Webmail 5.2.17 and 5.2.22 contain a path traversal vulnerability in the image-upload handling of Horde_Form_Type_image. The upload workflow uses an unsanitized user-controlled POST parameter as the destination path passed to PHP's file-moving operation. An attacker can manipulate this parameter to place an uploaded PHP file in a web-accessible, writable location, enabling remote code execution.

This repository contains a single Metasploit module (modules/exploits/multi/http/horde_form_file_upload.rb) targeting CVE-2019-9858, a file upload vulnerability in Horde Groupware Webmail (specifically with the Turba subcomponent and Horde Form < 2.0.19). The exploit requires valid user credentials and knowledge of the web root path. It authenticates to the Horde webmail interface, retrieves necessary CSRF tokens, and uploads a PHP payload using a crafted multipart/form-data POST request to /turba/add.php. The payload is written to the web root's static directory and then executed via an HTTP GET request, resulting in remote code execution. The module uses Metasploit's payload system, allowing for arbitrary PHP code execution (e.g., reverse shell, Meterpreter). The code is written in Ruby and leverages Metasploit's HttpClient and FileDropper mixins. The main endpoints involved are /login.php for authentication, /turba/add.php for file upload, and /static/<random>.php for payload execution. The repository is operational and suitable for authenticated remote code execution against vulnerable Horde installations.
