Assigner: Wordfence

Description

The Extensions for Leaflet Map plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'elevation-track' shortcode in all versions up to, and including, 4.14. This is due to insufficient input sanitization and output escaping on user supplied attributes. 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.

Attack-Flow Graph

Executive Summary

The Extensions for Leaflet Map plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'elevation-track' shortcode in all versions up to and including 4.14.

This vulnerability exists because the plugin does not properly sanitize or escape user-supplied input attributes.

As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages, which will execute whenever any user views those pages.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access or above to inject arbitrary scripts into web pages.

These scripts can execute in the context of other users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.

Because the attack is stored, the malicious script persists on the site and affects all users who access the infected pages.

Compliance Impact

The vulnerability allows authenticated attackers with Contributor-level access to inject arbitrary web scripts via Stored Cross-Site Scripting (XSS). This can lead to unauthorized access or manipulation of user data when users access the injected pages.

Such unauthorized data access or manipulation could potentially violate data protection requirements under standards like GDPR and HIPAA, which mandate safeguarding personal and sensitive information against unauthorized disclosure or alteration.

However, specific impacts on compliance depend on the context of use, the nature of the data involved, and the presence of mitigating controls.
