What the vulnerability does
The WordPress Visitors plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a spoofed HTTP Header value in versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the nm_vistior page.
Explanation of Vulnerability in Simple Terms
The WordPress Visitors plugin through version 1.0 contains a cross-site scripting (XSS) vulnerability that allows unauthenticated attackers to inject malicious scripts. The vulnerability affects the plugin's handling of user input without proper sanitization. An attacker can inject JavaScript that executes in visitors' browsers, potentially stealing session tokens or redirecting users to malicious sites. The scope is changed, meaning the impact extends beyond the plugin itself.
What an attacker can do
Inject JavaScript code that runs in visitors' browsers to steal data or redirect them to malicious sites.
Potential impact on your site
Visitors to your site may have their sessions hijacked, credentials stolen, or be redirected to phishing pages.
Conditions required to exploit
No authentication or user interaction required; attacker can exploit this remotely over the network.
