Vulnerability Overview

The Ads by datafeedr.com plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 1.1.3 via the 'dfads_ajax_load_ads' function.

Technical Analysis

REMEDIATION: Update to version 1.2.0, 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.
