Vulnerability Overview

The Filr – Secure document library plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to 1.2.3.5 (inclusive). This makes it possible for authenticated attackers, with author-level or above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 1.2.3.6, or a newer patched version --- IDENTIFIER: CWE-94 (Improper Control of Generation of Code ('Code Injection')) The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
