MailArchiver WordPress Plugin SQL Injection Vulnerability in Event Logging Feature

Vulnerability

A SQL injection vulnerability has been identified in the MailArchiver plugin for WordPress, affecting all versions through 4.5.0. The issue arises from inadequate escaping of user-supplied data in the 'logid' parameter, allowing authenticated attackers with Administrator-level access to manipulate SQL queries. Exploitation of this vulnerability could lead to unauthorized access to sensitive database information.

Impact

Exploitation allows authenticated users with Administrator privileges to inject and execute additional SQL commands, potentially leading to unauthorized data access or manipulation.

Reproduction

To reproduce this vulnerability, an authenticated user with Administrator privileges can send a request to the WordPress admin interface, including a crafted 'logid' parameter. The injected SQL payload must be designed to exploit the insufficient escaping and query preparation, appending malicious SQL that could, for example, extract sensitive information from the database.

Remediation

Users are advised to update the MailArchiver plugin to version 4.5.1 or a newer patched version.
