Detailsinfo

A vulnerability was found in fireplugins FireBox Plugin up to 3.1.13. It has been classified as critical. This affects the function preserveCampaignRoleAccess of the component Form Display Condition. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment plugin for WordPress is vulnerable to generic SQL Injection via FireBox Form Display Condition in all versions up to, and including, 3.1.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. On fresh installations of version 3.1.10 and later, exploitation requires administrator-level access; however, on sites upgraded from a version prior to 3.1.10, the preserveCampaignRoleAccess() migration grants the edit_fireboxes capability to any role that previously held edit_posts, reducing the minimum required privilege to Author-level.
