CVE-2024-56199 Details
Description
phpMyFAQ is an open source FAQ web application. Starting no later than version 3.2.10 and prior to version 4.0.2, an attacker can inject malicious HTML content into the FAQ editor at `http[:]//localhost/admin/index[.]php?action=editentry`, resulting in a complete disruption of the FAQ page's user interface. By injecting malformed HTML elements styled to cover the entire screen, an attacker can render the page unusable. This injection manipulates the page structure by introducing overlapping buttons, images, and iframes, breaking the intended layout and functionality. Exploiting this issue can lead to Denial of Service for legitimate users, damage to the user experience, and potential abuse in phishing or defacement attacks. Version 4.0.2 contains a patch for the vulnerability.
A stored HTML injection vulnerability has been identified in phpMyFAQ versions 3.2.10 prior to 4.0.2. This issue allows authenticated users to inject malicious HTML or JavaScript into the FAQ editor, which is then rendered without proper sanitization. The injected content can disrupt the user interface of the FAQ page by overlapping and obscuring buttons, images, and iframes, effectively rendering the page unusable. This exploitation can lead to a denial-of-service condition for legitimate users, degrade the overall user experience, and potentially be used for phishing or defacement attacks.
Users can upgrade to phpMyFAQ version 4.0.2 or later, where this vulnerability has been patched.
