CVE-2022-2552 Scanner

The Duplicator plugin is a widely used tool for WordPress, allowing users to create backups of their sites for easy migration or restoration. Developed by Snapcreek, this plugin is integral to website management for developers and administrators who rely on WordPress. It is especially useful for seamless site transfers between different domains or servers, helping in maintaining data integrity and minimizing downtime. The plugin is popular among users who need robust and reliable solutions for moving their WordPress setups. Its user-friendliness and comprehensive features make it a favorite in the WordPress community. However, like any software, maintaining its security is crucial to prevent potential vulnerabilities.

This vulnerability involves an information disclosure flaw present in the Duplicator WordPress plugin versions before 1.4.7.1. The flaw allows unauthenticated access to sensitive system information by exposing server details, PHP versions, and file paths without proper authorization. Attackers can leverage this vulnerability to gain insights into the server's configuration, potentially leading to further exploitation. The plugin's failure to authenticate or authorize access before displaying this information is a critical oversight. Such vulnerabilities can provide attackers with critical data to craft more precise attacks, putting server integrity at risk. The disclosure of system information should be limited only to authorized users to mitigate unwanted exposure.

The technical details of the vulnerability indicate a lack of adequate access control mechanisms in the Duplicator plugin. Specifically, the vulnerable endpoint is the main.installer.php file, found in the wp-content/backups-dup-lite directory. By making a GET request to this endpoint with the parameter view=1, attackers can retrieve sensitive information without needing authentication. This endpoint is crucial as it should ideally be protected to prevent data leakage. The presence of particular keywords such as 'SERVER DETAILS' in the response body confirms the information disclosure. Furthermore, a HTTP 200 status code upon successful exploitation signals the flaw's presence, necessitating immediate mitigation.

If malicious individuals exploit this vulnerability, they can gain unauthorized knowledge about the server's configuration and other critical details. Such information can be used for subsequent attacks, including but not limited to targeted SQL injections, cross-site scripting (XSS), or launching more sophisticated exploits. The disclosure of sensitive server and file path data can aid attackers in identifying other potential weak points within the infrastructure. Compromised systems could then face data breaches, service disruptions, or unauthorized data manipulations. The damage could extend to loss of user trust, legal penalties, and significant financial costs for remediation.
