CVE-2023-34020 Scanner Detail

The Uncanny Toolkit for LearnDash is a WordPress plugin that enhances the functionality of the LearnDash LMS (Learning Management System) by adding over a dozen new features. It is designed to make LearnDash more powerful and user-friendly for administrators, course creators, and students. This toolkit simplifies the management of LearnDash sites by providing modules that automate and streamline common tasks, improve user navigation, and extend the capabilities of LearnDash courses. It is widely used by educational institutions, training organizations, and individual educators to deliver online courses more effectively.

The Open Redirection vulnerability in the Uncanny Toolkit for LearnDash plugin allows attackers to redirect users to arbitrary external URLs by manipulating query parameters in a request. This could potentially be used for phishing attacks, misleading users by redirecting them from a trusted site to a malicious site designed to collect personal information or distribute malware. The vulnerability exploits the lack of proper validation and sanitization of the redirection target URL.

Specifically, the vulnerability is triggered through a manipulated URL that includes the plugin's 'redirect_url' parameter. An attacker crafts a URL that appends a malicious external link to this parameter. When an unsuspecting user clicks on this URL, they are redirected to the attacker's specified website. This issue arises due to the plugin's failure to adequately verify and sanitize input passed to the 'redirect_url' parameter before processing the redirection.

The primary risk associated with this vulnerability is the potential for phishing attacks, where attackers deceive users into providing sensitive information under the guise of a legitimate request. Additionally, this vulnerability could be used to redirect users to sites containing malicious content, including malware, potentially compromising the user's device security. Trust in the original site may also be undermined, damaging the reputation of organizations relying on LearnDash for their e-learning platforms.
