Multiple vulnerabilities have been discovered in Saurus CMS, 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 via the "pealkiri" parameter to admin/edit.php while editing articles is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

Successful exploitation requires that the attacker has "Article list" edit permissions.

2) The application allows users to perform certain actions via HTTP requests without making any validity checks to verify the requests. This can be exploited to e.g. change the password of the administrator, by tricking a logged in administrator into visiting a malicious web site.

The vulnerabilities are confirmed in version 4.7.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised. Do not visit malicious web sites or follow untruest links while being logged-in to the application.
