At a glance

CVE-2023-7002 is a high-severity Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the Backup Migration WordPress plugin, affecting versions <= 1.3.9. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 1.4.0; sites on affected versions should update now. Disclosed December 2023, reported by Françoa Taffarel.

Vulnerability Overview

The Backup Migration plugin for WordPress is vulnerable to OS Command Injection in all versions up to, and including, 1.3.9 via the 'url' parameter. This vulnerability allows authenticated attackers, with administrator-level permissions and above, to execute arbitrary commands on the host operating system.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Remediation

Update to version 1.4.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Backup Migration 1.4.0 closes this, and updating the plugin is the step that ends it.
