Smash Balloon Social Post Feed is a popular WordPress plugin used to display social media posts on a website, enhancing user engagement and content diversity. Developed by Smash Balloon, it aggregates posts from various social media platforms into a single feed that can be easily integrated into WordPress sites. This plugin is widely used by bloggers, businesses, and social media marketers to showcase their social media presence directly on their websites. It supports multiple social media platforms, making it a versatile tool for cross-platform social media management. The plugin aims to increase user interaction, site visit time, and the overall aesthetic appeal of websites.
This XSS vulnerability specifically targets the administrative interface of the Smash Balloon Social Post Feed plugin. An attacker must trick an authenticated administrator into clicking a specially crafted link containing malicious JavaScript. The vulnerable endpoint is '/wp-admin/admin.php', with the 'cff_access_token' parameter being susceptible to JavaScript injection. This parameter fails to properly sanitize input, allowing for the execution of arbitrary code. The exploitation of this vulnerability requires user interaction, making social engineering tactics a feasible approach for attackers.
Exploitation of the CVE-2021-25065 vulnerability can lead to several adverse effects. Attackers can hijack user sessions, redirect users to phishing or malware sites, alter the contents of the web page to display false information, or steal sensitive information such as passwords and session tokens. The impact is particularly severe for website administrators, as it can compromise the entire website and affect all users visiting the site.
