At a glance

CVE-2020-9335 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Photo Gallery by 10Web WordPress plugin, affecting versions <= 1.5.45. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). The issue is fixed in version 1.5.46; sites on affected versions should update now. Disclosed February 2020, reported by Vishnupriya Ilango.

Vulnerability Overview

Multiple stored XSS vulnerabilities exist in the 10Web Photo Gallery plugin before 1.5.46 WordPress. Successful exploitation of this vulnerability would allow a authenticated admin user to inject arbitrary JavaScript code that is viewed by other users.

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 Photo Gallery by 10Web <= 1.5.45 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 Photo Gallery by 10Web the fix is 1.5.46: builds <= 1.5.45 are affected, anything from 1.5.46 onward is not.

Remediation

Update to version 1.5.46, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Photo Gallery by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Photo Gallery by 10Web 1.5.46 closes this, and updating the plugin is the step that ends it.
