# CVE-2024-30270

> 6.2 MEDIUM · 🧪 PoC

## Beschreibung

mailcow: dockerized is an open source groupware/email suite based on docker. A security vulnerability has been identified in mailcow affecting versions prior to 2024-04. This vulnerability is a combination of path traversal and arbitrary code execution, specifically targeting the `rspamd_maps()` function. It allows authenticated admin users to overwrite any file writable by the www-data user by exploiting improper path validation. The exploit chain can lead to the execution of arbitrary commands on the server. Version 2024-04 contains a patch for the issue.

## Schwachstellen-Klasse

- **CWE-22** — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
  The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
