At a glance

This record tracks a high-severity Files or Directories Accessible to External Parties vulnerability in the miwoftp WordPress plugin, affecting versions < 1.0.5. It carries a CVSS score of 8.6 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 1.0.5; sites on affected versions should update now. Disclosed April 2015, reported by James Hooker.

Vulnerability Overview

The MiwoFTP plugin for WordPress is vulnerable to Arbitrary File Download in versions before 1.0.5. This is due to the improper use of a hook which utilizes a download file function. This makes it possible for unauthenticated attackers to arbitrarily download files located within the home directory of the affected site.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-552: Files or Directories Accessible to External Parties

The product makes files or directories accessible to unauthorized actors, even though they should not be.

Remediation

Update to version 1.0.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to miwoftp: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: miwoftp 1.0.5 closes this, and updating the plugin is the step that ends it.
