Vulnerability Overview

The Quiz And Survey Master plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 7.3.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. If the plugin setting "Require User Login" is disabled, this vulnerability can be exploited by unauthenticated attackers.

Technical Analysis

REMEDIATION: Update to version 7.3.11, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
