Vulnerability Overview

The Newscrunch theme for WordPress is vulnerable to arbitrary file uploads due to a missing capability check in the newscrunch_install_and_activate_plugin() function in all versions up to, and including, 1.8.4.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 1.8.4.1, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
