How to Fix CVE-2019-16751

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

devise_token_auth fixed: 1.1.3 
Upgrade devise_token_auth to 1.1.3
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 devise_token_auth

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-16751, inspect your project dependencies for Devise token auth:

inspect dependencies for devise_token_auth

Analyze the terminal output to locate any version of Devise token auth in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.3), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Devise token auth, 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

An issue was discovered in Devise Token Auth through 1.1.2. The omniauth failure endpoint is vulnerable to Reflected Cross Site Scripting (XSS) through the message parameter. Unauthenticated attackers can craft a URL that executes a malicious JavaScript payload in the victim's browser. This affects the `fallback_render` method in the omniauth callbacks controller.
