Cross-site scripting (XSS) vulnerability in the number_to_currency helper in actionpack/lib/action_view/helpers/number_helper.rb in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via the unit parameter.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1863 advisory.

    Red Hat Subscription Asset Manager acts as a proxy for handling     subscription information and software updates on client machines. Red Hat     Subscription Asset Manager is built on Ruby on Rails, a     model-view-controller (MVC) framework for web application development.
    Action Pack implements the controller and the view components.

    A directory traversal flaw was found in the way Ruby on Rails handled     wildcard segments in routes with implicit rendering. A remote attacker     could use this flaw to retrieve arbitrary local files accessible to a Ruby     on Rails application using the aforementioned routes via a specially     crafted request. (CVE-2014-0130)

    A flaw was found in the way Ruby on Rails handled hashes in certain     queries. A remote attacker could use this flaw to perform a denial of     service (resource consumption) attack by sending specially crafted queries     that would result in the creation of Ruby symbols, which were never garbage     collected. (CVE-2013-1854)

    Two cross-site scripting (XSS) flaws were found in Action Pack. A remote     attacker could use these flaws to conduct XSS attacks against users of an     application using Action Pack. (CVE-2013-1855, CVE-2013-1857)

    It was discovered that the internationalization component of Ruby on Rails     could, under certain circumstances, return a fallback HTML string that     contained user input. A remote attacker could possibly use this flaw to     perform a reflective cross-site scripting (XSS) attack by providing a     specially crafted input to an application using the aforementioned     component. (CVE-2013-4491)

    A denial of service flaw was found in the header handling component of     Action View. A remote attacker could send strings in specially crafted     headers that would be cached indefinitely, which would result in all     available system memory eventually being consumed. (CVE-2013-6414)

    It was found that the number_to_currency Action View helper did not     properly escape the unit parameter. An attacker could use this flaw to     perform a cross-site scripting (XSS) attack on an application that uses     data submitted by a user in the unit parameter. (CVE-2013-6415)

    Red Hat would like to thank Ruby on Rails upstream for reporting these     issues. Upstream acknowledges Ben Murphy as the original reporter of     CVE-2013-1854, Charlie Somerville as the original reporter of     CVE-2013-1855, Alan Jenkins as the original reporter of CVE-2013-1857,     Peter McLarnan as the original reporter of CVE-2013-4491, Toby Hsieh as the     original reporter of CVE-2013-6414, and Ankit Gupta as the original     reporter of CVE-2013-6415.

    All Subscription Asset Manager users are advised to upgrade to these     updated packages, which contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Toby Hsieh, Peter McLarnan, Ankit Gupta, Sudhir Rao and Kevin Reintjes discovered multiple cross-site scripting and denial of service vulnerabilities in Ruby Actionpack.

According to its self-reported version number, the Puppet Enterprise 3.x install on the remote host is prior to 3.1.1.  As a result, it is reportedly affected by multiple vulnerabilities :

  - An input validation error exists related to the     included Ruby version, handling string to floating point     conversions that could allow denial of service attacks     or arbitrary code execution. (CVE-2013-4164)

  - An error exists related to the included RubyGems     version and 'gem build', 'Gem::Package', and     'Gem::PackageTask' API calls that could allow denial     of service attacks. (CVE-2013-4363)

  - An error exists in the 'i18n' gem for Ruby that could     allow cross-site scripting attacks. (CVE-2013-4491)

  - An error exists related to handling temporary files     that could allow a local attacker to overwrite files by     using a symlink attack. (CVE-2013-4969)

  - An error exists related to the included Ruby on Rails,     'Action View', and handling certain headers that could     allow denial of service attacks. (CVE-2013-6414)

  - An input validation error exists related to the     included Ruby on Rails and the 'unit' parameter in the     'number_to_currency' helper that could allow cross-site     scripting attacks. (CVE-2013-6415)

  - An input validation error exists related to the     included Ruby on Rails, JSON parameter parsing and SQL     queries that could allow SQL injection attacks.
    (CVE-2013-6417)
