CVE-2024-6569 Scanner

Campaign Monitor for WordPress is a plugin used to integrate the Campaign Monitor's email marketing services with WordPress sites. It is widely used by website administrators and digital marketers to manage subscribers and automate email campaigns directly from WordPress. The plugin's functionality allows users to create and customize signup forms and track email performance metrics. Its integration capability with Campaign Monitor provides a seamless project management experience for various marketing campaigns conducted by businesses and bloggers alike. Nevertheless, vulnerabilities in plugins like these can be detrimental to the security of the platforms they reside on.

The information disclosure vulnerability detected in Campaign Monitor for WordPress arises from improper access restrictions and the enabling of error messages in the admin create.php view. This flaw allows unauthenticated attackers to retrieve server paths, which could assist in further malicious activities targeted at the website. By exploiting this weakness, attackers can gain insights into the file structure and configuration of the server hosting the site. Such exploits often begin with information gathering, making this vulnerability a valuable target for attackers.

The technical aspects of the vulnerability involve triggering processes within the create.php file, where inadequate restrictions coupled with display_errors being enabled lead to path disclosures. The vulnerable endpoint is accessible via HTTP requests to specific paths within the WordPress plugin's directory. Attackers craft requests that result in error states, revealing paths and potentially sensitive configuration information in the response. This path disclosure may subsequently be employed to inform and execute further attacks against the host system.

Exploitation of this information disclosure vulnerability can have significant consequences for the affected site. Malicious actors may gain insights into the server structure, facilitating escalations to more severe attacks such as code execution or file inclusion vulnerabilities. This level of access increases the likelihood of unauthorized data access or administrative control by the attacker. As a result, the integrity and security of the webserver can be compromised, potentially leading to data breaches and service disruptions.
