Vulnerability Overview

The WP Import – Ultimate CSV XML Importer for WordPress plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 7.28. This is due to the write_to_customfile() function writing unfiltered PHP code to a file. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject the customFunction.php file with PHP code that can be accessed to trigger remote code execution.

Technical Analysis

REMEDIATION: Update to version 7.29, 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.
