IPPlan 4.91a contains flaws that allow cross site request forgery and cross site scripting.

1) Input passed to the "grp" parameter in admin/usermanager 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.

2) 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. change the password, or add or delete arbitrary users when an administrative user visits a malicious web site.

The vulnerabilities are confirmed in version 4.91a. Other versions may also be affected.
