How to Fix CVE-2015-9284

To remediate this vulnerability, upgrade all affected Omniauth dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

omniauth fixed: 2.0.0 
Upgrade omniauth to 2.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for omniauth

How to Check if You Are Affected

To determine whether your application is affected by CVE-2015-9284, inspect your project dependencies for Omniauth:

inspect dependencies for omniauth

Analyze the terminal output to locate any version of Omniauth in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Omniauth, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The request phase of the OmniAuth Ruby gem (1.9.2 and earlier) is vulnerable to Cross-Site Request Forgery when used as part of the Ruby on Rails framework, allowing accounts to be connected without user intent, user interaction, or feedback to the user. This permits a secondary account to be able to sign into the web application as the primary account. As of v2 OmniAuth no longer has the vulnerable configuration by default, but it is still possible to configure OmniAuth in such a way that the web application becomes vulnerable to Cross-Site Request Forgery. There is a recommended remediation described [here](https://github.com/omniauth/omniauth/wiki/Resolving-CVE-2015-9284).
