Several cross-site-scripting and denial of service vulnerabilities were discovered in Ruby on Rails, a Ruby framework for web application development.

The remote host is running a version of Mac OS X 10.6 or 10.7 that does not have Security Update 2013-002 applied.  This update contains numerous security-related fixes for the following components :

  - CoreMedia Playback (10.7 only)
  - Directory Service (10.6 only)
  - OpenSSL
  - QuickDraw Manager
  - QuickTime
  - Ruby (10.6 only)
  - SMB (10.7 only)

The remote Mac OS X host has a version of OS X Server installed that is prior to 3.0. It is, therefore, affected by the following vulnerabilities :

  - A denial of service vulnerability exists in the     included JSON Ruby Gem, which can be abused to exhaust     all available memory resources. (CVE-2013-0269)

  - Multiple cross-site scripting vulnerabilities exist in     the included Ruby on Rails software. (CVE-2013-1854 /     CVE-2013-1855 / CVE-2013-1856 / CVE-2013-1857)

  - A buffer overflow exists in the included FreeRADIUS     software that can be triggered when parsing the 'not     after' timestamp in a client certificate when using     TLS-based EAP methods. (CVE-2012-3547)

  - A logic issue exists whereby the RADIUS service could     choose an incorrect certificate from a list of     configured certificates.

Fix for CVE-2013-1854.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Changes in rubygem-activerecord-3_2 :

  - add patch to fix security issue :

  - bug-809932_3-2-attribute_symbols.patch: fix     CVE-2013-1854: rubygem-activerecord*: Symbol DoS     vulnerability in Active Record (bnc#809932)

Updated Subscription Asset Manager 1.4 packages that fix multiple security issues are now available.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0699 advisory.

  - rubygem-activerecord: attribute_dos Symbol DoS vulnerability (CVE-2013-1854)

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

The remote host is affected by the vulnerability described in GLSA-201412-28 (Ruby on Rails: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Ruby on Rails. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could execute arbitrary code or cause a Denial of       Service condition. Furthermore, a remote attacker may be able to execute       arbitrary SQL commands, change parameter names for form inputs and make       changes to arbitrary records in the system, bypass intended access       restrictions, render arbitrary views, inject arbitrary web script or       HTML, or conduct cross-site request forgery (CSRF) attacks.
  Workaround :

    There is no known workaround at this time.
