Page Builder: Pagelayer – Drag and Drop website builder

The Page Builder: Pagelayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Button widget's Custom Attributes field in all versions up to, and including, 2.0.8. This is due to an incomplete event handler blocklist in the 'pagelayer_xss_content' XSS filtering function, which blocks common, but not all, event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Improper Neutralization of CRLF Sequences ('CRLF Injection') in all versions up to, and including, 2.0.7. This is due to the contact form handler performing placeholder substitution on attacker-controlled form fields and then passing the resulting values into email headers without removing CR/LF characters. This makes it possible for unauthenticated attackers to inject arbitrary email headers (for example Bcc / Cc) and abuse form email delivery via the 'email' parameter granted they can target a contact form configured to use placeholders in mail template headers.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.0.8. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive user or configuration data.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.5 via the pagelayer_replace_page function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to replace media files belonging to other users, including administrators.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘login_url’ parameter in all versions up to, and including, 2.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. A valid username/password pair needs to be supplied in order to be successfully exploited and any injected scripts will only execute in the context of that authenticated user.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to unauthorized post publication due to insufficient validation on the pagelayer_save_content() function in all versions up to, and including, 1.9.8. This makes it possible for authenticated attackers, with Contributor-level access and above, to bypass post moderation and publish posts to the site.

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.9.8. This is due to missing or incorrect nonce validation on the pagelayer_save_post function. This makes it possible for unauthenticated attackers to modify post contents via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

The PageLayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.9.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
