Vulnerability Overview

The Hustle (aka wordpress-popup) plugin 6.0.7 for WordPress is vulnerable to CSV Injection as it allows for injecting malicious code into a pop-up window. Successful exploitation grants an attacker with a right to execute malicious code on the administrator's computer through Excel functions as the plugin does not sanitize the user's input and allows insertion of any text.

Technical Analysis

REMEDIATION: Update to version 6.0.8.1, or a newer patched version --- IDENTIFIER: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')) The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
