CVE-2020-3719

Vulnerability

Description

CVE-2020-3719 is an SQL injection vulnerability in Adobe Magento (formerly Magento Commerce and Magento Open Source). According to the official description, the flaw affects Magento versions 2.3.3 and earlier, 2.2.10 and earlier, 1.14.4.3 and earlier, and 1.9.4.3 and earlier [1]. The root cause is improper sanitization of user-supplied input, allowing an attacker to inject SQL commands into database queries.

Exploitation

Prerequisites

Attackers can exploit this vulnerability by sending crafted requests to the Magento application, likely through an exposed web interface. No authentication is mentioned as a prerequisite, but the vulnerable components may require certain user permissions depending on the Magento version. The vulnerability is categorized as an SQL injection, meaning an attacker could inject malicious SQL statements through input fields or API parameters [1].

Impact

Successful exploitation could lead to sensitive information disclosure [1]. This could include customer data, order details, admin credentials, or other configuration information stored in the Magento database. Since SQL injection can sometimes allow data modification or deletion, the impact may extend beyond disclosure, though the official description and references only mention information disclosure.

Mitigation

Adobe has released security patches to address CVE-2020-3719. Affected users should upgrade to Magento versions later than 2.3.3, 2.2.10, 1.14.4.3, or 1.9.4.3 as applicable. Users still running Magento 1.x (End of Life since June 2020) should either upgrade to Magento 2 or apply any available security patches. The official Magento GitHub repository [2] may contain details on the specific fixes and updated code.
