Description:
mrzayas.es has discovered some vulnerabilities in Nuke ET, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site request forgery attacks.
1) Input passed to the "mensaje" parameter when sending private messages is not properly sanitised before being stored. This can be exploited to insert <div> HTML elements with JavaScript code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
Successful exploitation requires that both the attacker and the victim have valid user credentials, and that the victim uses e.g. Internet Explorer.
2) The problem is caused due to the application allowing users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited e.g. to conduct script insertion or cross-site scripting attacks by tricking an administrator into opening a malicious web page.
The vulnerabilities are confirmed in version 3.4 and reported in version 3.2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised. Do not browse untrusted websites while being logged on to the application.
