CVE-2020-9583

CVE-2020-9583 is a command injection vulnerability affecting multiple Magento editions and versions: Magento Open Source (formerly Community Edition) up to 2.3.4 and 2.2.11, as well as Magento Commerce (formerly Enterprise Edition) up to 1.14.4.4 and Magento Open Source up to 1.9.4.4 [1]. The vulnerability resides in the way the application handles certain input, allowing an attacker to inject operating system commands into a vulnerable function.

An attacker can exploit this vulnerability without requiring administrative privileges, though some access to the Magento admin panel may be necessary depending on the specific attack vector [1]. The attack surface is primarily through HTTP requests that are processed by the Magento application, where unsanitized or improperly validated command input can be inserted into system calls.

Successful exploitation of this command injection flaw can lead to arbitrary code execution on the underlying server [1]. This means an attacker could potentially execute any system command, install malware, access sensitive data, or compromise the entire e-commerce platform and its connected systems.

Adobe has addressed this vulnerability in security updates for the affected versions [2]. Users are strongly advised to upgrade to Magento 2.3.5, 2.2.12, 1.14.4.5, or 1.9.4.5 respectively, or apply the relevant security patch as provided by Adobe [1][2]. Workarounds may include restricting access to the Magento admin interface and web application firewall rules, but patching is the definitive mitigation.
