Some vulnerabilities have been discovered in Limbo, which can be exploited by malicious people to conduct cross-site scripting, cross-site request forgery, and SQL injection attacks.

1) Input passed to the "com_option" parameter in admin.php 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.

Successful exploitation of this vulnerability requires that the target user is logged in as administrator.

2) Input passed to the "cuid" cookie in admin.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability allows e.g. retrieving administrator password hashes, but requires that the product is configured to use an SQL database.

3) 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. add administrative users when a logged-in administrator visits a malicious web page.

The vulnerabilities are confirmed in version 1.0.4.2 Sec Fixed. Other versions may also be affected.

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