Vulnerability Overview

The Import XML and RSS Feeds for WordPress is vulnerable to remote code execution in versions up to, and including, 2.1.4. This is due to the plugin vendor leaving a malicious file behind when patching CVE-2023-4300. This makes it possible for unauthenticated attackers to access the 169227090864de013cac47b.php file and achieve remote code execution.

Technical Analysis

REMEDIATION: Update to version 2.1.5, 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.
