At a glance

CVE-2023-6164 is a low-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the MainWP Dashboard WordPress plugin, affecting versions <= 4.5.1.2. It carries a CVSS score of 2.2 (reachable over the network). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 4.5.1.3; sites on affected versions should update now. Disclosed October 2023, reported by Hüseyin TINTAŞ.

Vulnerability Overview

The MainWP Dashboard – WordPress Manager for Multiple Websites Maintenance plugin for WordPress is vulnerable to CSS Injection via the ‘newColor’ parameter in all versions up to, and including, 4.5.1.2 due to insufficient input sanitization. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary CSS values into the site tags.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

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

Remediation

Update to version 4.5.1.3, or a newer patched version

How does WordSec protect against this?

An attacker needs Administrator 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. None of that substitutes for the fix: MainWP Dashboard 4.5.1.3 closes this, and updating the plugin is the step that ends it.
