How to Fix CVE-2022-31069

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

@finastra/nestjs-proxy fixed: 0.7.0 
npm install @finastra/nestjs-proxy@0.7.0
Verify Direct and Transitive Dependencies

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

npm ls @finastra/nestjs-proxy

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-31069, inspect your project dependencies using npm:

npm ls @finastra/nestjs-proxy

Analyze the terminal output to locate any version of @finastra/nestjs proxy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

Note: The npm ls @finastra/nestjs-proxy command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In @finastra/nestjs proxy, 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 nestjs-proxy library did not have a way to control when Authorization headers should should be forwarded for specific backend services configured by the application developer. This could have resulted in sensitive information such as OAuth bearer access tokens being inadvertently exposed to such services that should not see them. A new feature has been introduced in the patched version of nestjs-proxy that allows application developers to opt out of forwarding the Authorization headers on a per service basis using the `forwardToken` config setting. Developers are advised to review the README for this library on Github or NPM for further details on how this configuration can be applied. ### Patches - This issue has been fixed in version 0.7.0 of `@finastra/nestjs-proxy`. - Users of `@ffdc/nestjs-proxy` are advised that this package has been deprecated and is no longer being maintained or receiving updates. Please update your package.json file to use `@finastra/nestjs-proxy` instead. ### References - https://github.com/Finastra/finastra-nodejs-libs/pull/231 - https://github.com/Finastra/finastra-nodejs-libs/blob/master/libs/proxy/README.md
