actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain "['xyz', nil]" values, a related issue to CVE-2012-2660.

actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.0.13, 3.1.x before 3.1.5, and 3.2.x before 3.2.4 does not properly consider differences in parameter handling between the Active Record component and the Rack interface, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks via a crafted request, as demonstrated by certain "[nil]" values, a related issue to CVE-2012-2694.

The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.

Cross-site scripting (XSS) vulnerability in Ruby on Rails 2.x before 2.2.3, and 2.3.x before 2.3.4, allows remote attackers to inject arbitrary web script or HTML by placing malformed Unicode strings into a form helper.

Multiple cross-site scripting (XSS) vulnerabilities in the mail_to helper in Ruby on Rails before 2.3.11, and 3.x before 3.0.4, when javascript encoding is used, allow remote attackers to inject arbitrary web script or HTML via a crafted (1) name or (2) email value.

Cross-site scripting (XSS) vulnerability in the strip_tags helper in actionpack/lib/action_controller/vendor/html-scanner/html/node.rb in Ruby on Rails before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a tag with an invalid name.

The template selection functionality in actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.10 and 3.1.x before 3.1.0.rc6 does not properly handle glob characters, which allows remote attackers to render arbitrary views via a crafted URL, related to a "filter skipping vulnerability."

The to_s method in actionpack/lib/action_dispatch/middleware/remote_ip.rb in Ruby on Rails 3.0.5 does not validate the X-Forwarded-For header in requests from IP addresses on a Class C network, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header.

Ruby on Rails 2.1 before 2.1.3 and 2.2.x before 2.2.2 does not verify tokens for requests with certain content types, which allows remote attackers to bypass cross-site request forgery (CSRF) protection for requests to applications that rely on this protection, as demonstrated using text/plain.

actionpack/lib/action_view/template/resolver.rb in Ruby on Rails 3.0.x before 3.0.4, when a case-insensitive filesystem is used, does not properly implement filters associated with the list of available templates, which allows remote attackers to bypass intended access restrictions via an action name that uses an unintended case for alphabetic characters.

A certain algorithm in Ruby on Rails 2.1.0 through 2.2.2, and 2.3.x before 2.3.4, leaks information about the complexity of message-digest signature verification in the cookie store, which might allow remote attackers to forge a digest via multiple attempts.

Ruby on Rails 2.1.x, 2.2.x, and 2.3.x before 2.3.11, and 3.x before 3.0.4, does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via forged (1) AJAX or (2) API requests that leverage "combinations of browser plugins and HTTP redirects," a related issue to CVE-2011-0696.

There is a possible XSS vulnerability in Action View. Text declared as HTML safe will not have quotes escaped when used as attribute values in tag helpers.

Applications that pass unverified user input to the render method in a controller or a view may be vulnerable to a code injection. An attacker could use the request parameters to coerce the controller to execute arbitrary ruby code.

Applications that pass unverified user input to the render method in a controller may be vulnerable to an information leak vulnerability. Impacted code will look something like this: def index; render params[:id]; end. Carefully crafted requests can cause the above code to render files from unexpected places like outside the application's view directory, and can possibly escalate this to a remote code execution attack.

Due to the way that Action Controller compares user names and passwords in basic authentication authorization code, it is possible for an attacker to analyze the time taken by a response and intuit the password. You can tell you application is vulnerable to this attack by looking for http_basic_authenticate_with method calls in your application.

A carefully crafted Accept header can cause a global cache of mime types to grow indefinitely which can lead to a possible denial of service attack in Action Pack.

Applications that pass unverified user input to the render method in a controller may be vulnerable to an information leak vulnerability. Carefully crafted requests can render files from unexpected places like outside the application's view directory, and can possibly escalate this to a remote code execution attack.

Users that have a route that contains the string :controller are susceptible to objects being leaked globally which can lead to unbounded memory growth. To identify if your application is vulnerable, look for routes that contain :controller.

Specially crafted requests can be used to determine whether a file exists on the filesystem that is outside the Rails application's root directory. The files will not be served, but attackers can determine whether the file exists. This only impacts Rails applications that enable static file serving at runtime. For example, the application's production configuration will say: config.serve_static_assets = true

Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails, when certain route globbing configurations are enabled, allows remote attackers to read arbitrary files via a crafted request.

Multiple cross-site scripting (XSS) vulnerabilities in actionview/lib/action_view/helpers/number_helper.rb in Ruby on Rails beta2 allow remote attackers to inject arbitrary web script or HTML via the (1) format, (2) negative_format, or (3) units parameter to the (a) number_to_currency, (b) number_to_percentage, or (c) number_to_human helper.

actionpack/lib/action_view/template/text.rb in Action View in Ruby on Rails converts MIME type strings to symbols during use of the :text option to the render method, which allows remote attackers to cause a denial of service (memory consumption) by including these strings in headers.

actionpack/lib/action_view/lookup_context.rb in Action View in Ruby on Rails allows remote attackers to cause a denial of service (memory consumption) via a header containing an invalid MIME type that leads to excessive caching.

The simple_format helper converts user supplied text into html text which is intended to be safe for display. A change made to the implementation of this helper means that any user provided HTML attributes will not be escaped correctly. As a result of this error, applications which pass user-controlled data to be included as html attributes will be vulnerable to an XSS attack.

The number_to_currency helper allows users to nicely format a numeric value. The unit parameter is not escaped correctly. Application which pass user controlled data as the unit parameter are vulnerable to an XSS attack.

There is a vulnerability in the internationalisation component of Ruby on Rails. When the i18n gem is unable to provide a translation for a given string, it creates a fallback HTML string. Under certain common configurations this string can contain user input which would allow an attacker to execute a reflective XSS attack.

Due to the way that Rack::Request and Rails::Request interact, it is possible for a 3rd party or custom rack middleware to parse the parameters insecurely and store them in the same key that Rails uses for its own parameters. In the event that happens the application will receive unsafe parameters and could be vulnerable to the earlier vulnerability: it would be possible for an attacker to issue unexpected database queries …

The sanitize helper in Ruby on Rails is designed to filter HTML and remove all tags and attributes which could be malicious.

Carefully crafted text can bypass the sanitization provided in the sanitize_css method in Action Pack.

There are multiple weaknesses in the parameter parsing code for Ruby on Rails which allows attackers to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on a Rails application.

There is an XSS vulnerability in the strip_tags helper in Ruby on Rails, the helper does not correctly handle malformed html. As a result, an attacker can execute arbitrary javascript through the use of specially crafted malformed html. All users who rely on strip_tags for XSS protection should upgrade or use the work around immediately.

When a value for the prompt field is supplied to the select_tag helper, the value is not escaped. If untrusted data is not escaped, and is supplied as the prompt value, there is a potential for XSS attacks.

All users using Digest Authentication support in Rails should upgrade immediately. Impacted code uses any of the with_http_digest controller helper methods.

Ruby on Rails is vulnerable to remote cross-site scripting because the application does not validate manually generated select tag options upon submission to actionpack/lib/action_view/helpers/form_options_helper.rb. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.

The helper method for i18n translations has a convention whereby translations strings with a name ending in 'html' are considered HTML safe. There is also a mechanism for interpolation. It has been discovered that these 'html' strings allow arbitrary values to be contained in the interpolated input, and these values are not escaped.

A response splitting flaw can allow a remote attacker to inject arbitrary HTTP headers into a response due to insufficient sanitization of the values provided for response content types.
