SB2019011512 - Code Injection in WooCommerce WooCommerce

Description

This security bulletin contains information about 1 vulnerability.

1) Code Injection (CVE-ID: CVE-2017-18356)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote authenticated user to execute arbitrary code.

In the Automattic WooCommerce plugin before 3.2.4 for WordPress, an attack is possible after gaining access to the target site with a user account that has at least Shop manager privileges. The attacker then constructs a specifically crafted string that will turn into a PHP object injection involving the includes/shortcodes/class-wc-shortcode-products.php WC_Shortcode_Products::get_products() use of cached queries within shortcodes.
