WordPress Plugin Vulnerabilities

Download Manager <= 2.7.94 - Authenticated Stored XSS

Description

The stored XSS vulnerability allows any authenticated user to inject malicious code via the name of the uploaded file:

Example: <svg onload=alert(0)>.jpg

The vulnerability exists because the file name is not properly sanitized 
and this can lead to malicious code injection that will be executed on the 
target’s browser.

Proof of Concept

1. The attacker creates a new download package via the plugin's menu
and uploads a file with the name: <svg onload=alert(0)>.jpg 

2. The stored XSS can be triggered when an authenticated user (e.g. admin)
attempts to edit this download package
