CVE-2024-13713 in WPExperts Square for GiveWP Plugin
Summary
by MITRE • 02/21/2025
The WPExperts Square For GiveWP plugin for WordPress is vulnerable to SQL Injection via the 'post' parameter in all versions up to, and including, 1.3.1 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 Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WPExperts Square For GiveWP plugin presents a critical sql injection vulnerability that compromises the integrity of wordpress installations. This vulnerability exists within the plugin's handling of user-supplied input through the 'post' parameter, affecting all versions up to and including 1.3.1. The flaw stems from inadequate input sanitization and insufficient sql query preparation mechanisms that fail to properly escape malicious input before processing. Attackers with subscriber-level privileges or higher can exploit this weakness to manipulate existing sql queries and extract sensitive data from the underlying database.
The technical implementation of this vulnerability demonstrates a classic sql injection flaw that aligns with common weakness enumeration cwes 89 and 77. The plugin fails to employ proper parameterized queries or adequate input validation when processing the 'post' parameter, allowing malicious users to inject additional sql commands into existing queries. This vulnerability operates at the application layer and represents a significant risk to database security since it enables attackers to bypass normal access controls and retrieve confidential information from the wordpress database.
From an operational perspective, this vulnerability creates substantial risk for wordpress sites utilizing the affected plugin. The requirement for only subscriber-level access to exploit the vulnerability means that even relatively low-privilege users can potentially gain unauthorized access to sensitive data including user credentials, personal information, and administrative details. The impact extends beyond simple data theft as attackers could potentially modify database contents, escalate privileges, or use the extracted information for further attacks within the wordpress environment. This vulnerability particularly affects sites that store sensitive user information or financial data through givewp donations.
The exploitation of this vulnerability follows established attack patterns documented in the attack tree framework where authenticated attackers leverage insufficient input validation to achieve unauthorized database access. Mitigation strategies should prioritize immediate plugin updates to versions that address the sql injection flaw, implementation of web application firewalls to detect and block malicious sql injection attempts, and regular database access monitoring to identify unusual query patterns. Additionally, administrators should enforce the principle of least privilege by limiting subscriber permissions and implementing proper input validation controls. The vulnerability also highlights the importance of regular security audits and penetration testing to identify similar weaknesses in wordpress plugins and themes that may not be immediately apparent through standard security scanning processes.
