Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Creative Themes Blocksy allows Stored XSS.This issue affects Blocksy: from n/a through 2.0.19.

Neutralización inadecuada de la entrada durante la vulnerabilidad de generación de páginas web ('Cross-site Scripting') en Creative Themes Blocksy permite almacenar XSS. Este problema afecta a Blocksy: desde n/a hasta 2.0.19.

The Blocksy theme for WordPress is vulnerable to Stored Cross-Site Scripting via headers/footers in all versions up to, and including, 2.0.19 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
