At a glance

CVE-2022-1320 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Slider by 10Web WordPress plugin, affecting versions <= 1.2.51. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). The issue is fixed in version 1.2.52; sites on affected versions should update now. Disclosed April 2022, reported by Fayçal Chena.

Vulnerability Overview

The Sliderby10Web WordPress plugin before 1.2.52 does not properly sanitize and escape some of its settings, which could allow high-privileged users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Slider by 10Web <= 1.2.51 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Slider by 10Web the fix is 1.2.52: builds <= 1.2.51 are affected, anything from 1.2.52 onward is not.

Remediation

Update to version 1.2.52, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Slider by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Slider by 10Web 1.2.52 closes this, and updating the plugin is the step that ends it.
