WordPress vulnerability analysis and mitigation

Overview

The Modern Events Calendar Lite plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter of the 'wpajaxmecloadsingle_page' AJAX action in versions up to and including 6.3.0. This vulnerability exists due to insufficient escaping of user-supplied parameters and inadequate preparation of SQL queries (NVD).

Technical details

The vulnerability is classified as SQL Injection (CWE-89) with a CVSS v3.1 Base Score of 5.9 (MEDIUM). The attack vector is network-accessible (AV:N) with high attack complexity (AC:H), requiring no privileges (PR:N) or user interaction (UI:N). The scope is unchanged (S:U) with potential for high confidentiality impact (C:H) but no impact on integrity (I:N) or availability (A:N) (NVD).

Impact

The vulnerability allows unauthenticated attackers to append additional SQL queries to existing queries, potentially extracting sensitive information from the database. This is only exploitable on sites with addslashes disabled (NVD).

Mitigation and workarounds

The vulnerability was fixed in version 6.4.0 of the Modern Events Calendar Lite plugin. Users should update to this version or later to mitigate the risk (WordPress Plugin).
