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 reported a vulnerability in GENU, which can be exploited by malicious people to conduct cross-site request forgery attacks.
The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. delete arbitrary user accounts by tricking a logged in administrator into visiting a malicious web site.
The vulnerability is reported in version 2012.4 and confirmed in version 2012.3. Other versions may also be affected.
Do not browse untrusted sites or follow untrusted links while being logged-in to the application.
