Summary

The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    descriptionThe 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.

    descriptionUpdated 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.

    descriptionUpdated ruby193-rubygem-activerecord packages that fix one security issue are now available for Red Hat OpenShift Enterprise 1.1.3. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. Ruby on Rails is a model-view-controller (MVC) framework for web application development. Active Record implements object-relational mapping for accessing database entries using objects. A flaw was found in the way hashes were handled 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.
