Cross-Site Scripting

Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.

Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".

Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.

A vulnerability has been discovered in the Track That Stat plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "data" parameter in wp-content/plugins/track-that-stat/js/trackthatstat.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerability is confirmed in version 1.0.8. Other versions may also be affected.

Update to version 1.1.0.
