Summary
by MITRE • 09/25/2024
The Spreadsheet Integration – Automate Google Sheets With WordPress, WooCommerce & Most Popular Form Plugins. Also, Display Google sheet as a Table. plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 3.7.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to edit post status, edit Google sheet integrations, and create Google sheet integrations.

The CVE-2024-6590 vulnerability affects the Spreadsheet Integration plugin for WordPress, a widely used tool that enables integration with Google Sheets for WordPress, WooCommerce, and various form plugins. This plugin allows users to display Google Sheets as tables within WordPress environments. The vulnerability stems from insufficient access control mechanisms within the plugin's codebase, specifically missing capability checks on critical functions that handle data modification operations. Attackers exploiting this weakness can manipulate the plugin's functionality without proper authorization, potentially compromising the integrity of integrated data flows between WordPress and Google Sheets systems. The vulnerability impacts all versions up to and including 3.7.9, making it a significant concern for WordPress administrators who have not yet updated their installations.
The technical flaw manifests as a lack of proper capability verification within the plugin's core functions, which should enforce access controls based on user roles and permissions. This missing validation allows authenticated users with Subscriber-level access or higher to perform operations that should typically require administrator privileges. The vulnerability specifically affects functions responsible for modifying post statuses, editing existing Google sheet integrations, and creating new integration configurations. Without proper capability checks, these functions execute regardless of the user's permission level, creating an unauthorized modification path. This type of flaw aligns with CWE-285, which addresses insufficient authorization in software systems, and represents a classic privilege escalation vulnerability that can be exploited through the principle of least privilege violations.
The operational impact of this vulnerability extends beyond simple data manipulation to potentially compromise entire WordPress installations and their integrated data ecosystems. Attackers with Subscriber-level access can modify Google Sheet integrations, which may contain sensitive business data, customer information, or financial records. The ability to edit post statuses through this vulnerability could enable attackers to manipulate content visibility, potentially hiding malicious modifications or creating backdoors within the WordPress environment. Additionally, the capability to create new Google sheet integrations allows attackers to establish persistent access points that can be used for data exfiltration or further exploitation of the WordPress system. This vulnerability creates a pathway for attackers to gain deeper access to WordPress functionality and can facilitate more complex attack vectors including data corruption, information disclosure, or even full system compromise.
Organizations should immediately implement mitigation strategies to address this vulnerability by updating to the latest version of the Spreadsheet Integration plugin where the capability checks have been properly implemented. System administrators should also review user permissions and ensure that only trusted individuals have Subscriber-level access or higher to WordPress installations. Monitoring for unusual activity related to Google Sheet integrations and post status modifications should be implemented to detect potential exploitation attempts. The vulnerability demonstrates the critical importance of proper access control implementation in WordPress plugins and highlights the need for regular security auditing of third-party software components. Organizations should consider implementing network segmentation and additional monitoring controls around WordPress environments to reduce the impact of similar vulnerabilities. This case exemplifies the ATT&CK technique of privilege escalation through software vulnerabilities, where attackers leverage weak access controls to gain unauthorized capabilities within web applications.
