Official description

The Cookie Notice & Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the uuid parameter in all versions up to, and including, 1.6.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The underlying weakness: Improper Neutralization of Script-Related HTML Tags in a Web Page

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.

How developers prevent this class of flaw

  • With Struts, write all data from form beans with the bean's filter attribute set to true.
