Description

The Sticky Chat Widget plugin for WordPress is vulnerable to SQL Injection via the 'scw_form_fields' parameter array keys of the 'scw_save_form_data' AJAX action in versions up to, and including, 1.4.2. This is due to the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(), which wraps column identifiers in backticks without escaping them, allowing a backtick in an attacker-supplied key to break out of the column-identifier list into raw SQL; additionally, the use of filter_input() bypasses WordPress's wp_magic_quotes() protection, and the widget_id validation loop is skipped entirely when no valid widget_id is supplied, leaving $isValid at 1. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The Sticky Chat Widget plugin for WordPress has a SQL Injection vulnerability in versions up to 1.4.2. Attackers can exploit the 'scw_form_fields' parameter in the 'scw_save_form_data' AJAX action to inject malicious SQL queries. This happens because the plugin passes user-controlled input directly to a database query without proper sanitization, allowing attackers to extract sensitive data from the database.

Detection Guidance

This vulnerability is specific to the Sticky Chat Widget WordPress plugin. To detect it, check if the plugin version is up to and including 1.4.2. Use WordPress admin to inspect installed plugins or run SQL queries on the WordPress database to check the plugin version in the wp_options table.

Impact Analysis

Unauthenticated attackers can exploit this to extract sensitive information from the WordPress database, such as user credentials, personal data, or other confidential details. This could lead to data breaches, unauthorized access, or further attacks on the system.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations using this plugin may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Immediately update the Sticky Chat Widget plugin to the latest version if available. If no update is available, consider disabling or removing the plugin until a patch is released. Ensure your WordPress core and all plugins are regularly updated to prevent similar issues.
