CVE-2024-3561: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in mgibbs189 Custom Field Suite
The Custom Field Suite plugin for WordPress is vulnerable to SQL Injection via the the 'Term' custom field in all versions up to, and including, 2.6.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2024-3561 is an SQL Injection vulnerability in the Custom Field Suite WordPress plugin (versions up to 2.6.7). The flaw arises from improper neutralization of special elements in the 'Term' custom field parameter, due to insufficient escaping and lack of prepared statements. This enables authenticated users with contributor-level access or higher to inject additional SQL queries, potentially leading to unauthorized data disclosure and full compromise of confidentiality, integrity, and availability of the database.
Potential Impact
Successful exploitation can lead to extraction of sensitive information from the database and potentially full compromise of the affected WordPress site's data. The vulnerability affects the confidentiality, integrity, and availability of the database. It requires authenticated access with contributor-level privileges or higher, limiting the attack surface to users with some level of trust on the site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level and higher access to trusted users only. Monitor for updates from the plugin vendor or WordPress security advisories to apply any forthcoming patches promptly.
