Two vulnerabilities have been discovered in Ushahidi, which can be exploited by malicious people to conduct cross-site request forgery and script insertion attacks.
1) 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. create an arbitrary user with administrative privileges if a logged-in administrative user visits a malicious web site.
2) Input passed via the "name" parameter to index.php/login (when parameter "action" is set to "new") when creating an user account is not properly sanitised before being used. 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.
The vulnerabilities are confirmed in version 2.2. Other versions may also be affected.
