Detailsinfo

A vulnerability, which was classified as problematic, has been found in cozyvision1 SMS Alert Plugin up to 3.9.7. This issue affects the function SA_CodTOPrepaid::sendSms of the component Settings. The manipulation of the argument checkout_payment_plans/order_status with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to generic SQL Injection via 'checkout_payment_plans' and 'order_status' Settings in all versions up to, and including, 3.9.7 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: the malicious payload is stored in the 'checkout_payment_plans' and 'order_status' settings via update_option() and executed later when the cod_to_prepaid_cart_notification_sendsms_hook WP-Cron event fires SA_CodTOPrepaid::sendSms().
