At a glance

CVE-2021-24519 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the VikRentCar Car Rental Management System WordPress plugin, affecting versions < 1.1.10. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 1.1.10; sites on affected versions should update now. Disclosed July 2021, reported by Muhammad Daffa.

Vulnerability Overview

The VikRentCar Car Rental Management System WordPress plugin before 1.1.10 does not sanitise the 'Text Next to Icon' field when adding or editing a Characteristic, allowing high privilege users such as admin to use XSS payload in it, leading to an authenticated Stored Cross-Site Scripting issue.

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 VikRentCar Car Rental Management System < 1.1.10 takes an account at Admin level or above. 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 VikRentCar Car Rental Management System the fix is 1.1.10: builds < 1.1.10 are affected, anything from 1.1.10 onward is not.

Remediation

Update to version 1.1.10, 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. None of that substitutes for the fix: VikRentCar Car Rental Management System 1.1.10 closes this, and updating the plugin is the step that ends it.
