Some vulnerabilities have been reported in Ruby on Rails, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting and HTTP response splitting attacks, and conduct SQL injection attacks.

1) Input passed to the "quote_table_name" method is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary code.

2) An error within the template selection mechanism can be exploited to force the application to render using a restricted view.

Successful exploitation requires that the application uses "action:" within its routes.

Note: This vulnerability only affects version 3.0.0 and later.

3) The content type handling does not properly sanitise certain input before returning it to the user. This can be exploited to insert arbitrary HTTP headers, which are included in a response sent to the user.

Note: This vulnerability only affects version 2.3.x.

4) The "strip_tags" function does not properly sanitise certain input, which can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

5) The escaping mechanism does not properly handle certain Unicode sequences, which can be exploited to bypass the escaping mechanism and e.g. conduct cross-site scripting attacks.

Solution
Update to version 2.3.14 or 3.0.10.
