At a glance
CVE-2019-19134 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Hero Maps Premium WordPress plugin, affecting versions <= 2.2.2. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.2.3; sites on affected versions should update now. Disclosed February 2020, reported by Hooper Labs.
Vulnerability Overview
The Hero Maps Premium plugin 2.2.2 and prior for WordPress is prone to unauthenticated XSS via the views/dashboard/index.php p parameter because it fails to sufficiently sanitize user-supplied input. An attacker may leverage this issue to inject HTML or arbitrary JavaScript within the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based tokens or to launch other attacks.
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 privileges on the target site.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Hero Maps Premium <= 2.2.2 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 Hero Maps Premium the fix is 2.2.3: builds <= 2.2.2 are affected, anything from 2.2.3 onward is not.
Remediation
Update to version 2.2.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Hero Maps Premium: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Hero Maps Premium 2.2.3 closes this, and updating the plugin is the step that ends it.
