What the vulnerability does
The Watu Quiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the HTTP Referer header in versions less than, or equal to, 3.4.4 due to insufficient input sanitization and output escaping when the "Save source URL" option is enabled. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Watu Quiz versions 3.4.4 and earlier contain a cross-site scripting (XSS) vulnerability that allows unauthenticated attackers to inject malicious scripts into the application. The vulnerability can be exploited over the network without user interaction, and the impact extends beyond the vulnerable component. This can lead to unauthorized access to user data or session hijacking.
What an attacker can do
Inject malicious JavaScript that executes in users' browsers and steals session data or credentials.
Potential impact on your site
Visitors' browsers may execute attacker-controlled code, compromising user accounts and site data.
Conditions required to exploit
No authentication or user interaction required; attacker can exploit remotely.
