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.

Chokri B.A. has discovered a vulnerability in GetSimple CMS, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "path" parameter in admin/upload.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 versions 3.1 and 3.1.2. Other versions may also be affected.

Update to version 3.2.0.
