How to Fix CVE-2017-16005

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

http-signature fixed: 0.10.0
npm install http-signature@0.10.0
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 http-signature

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-16005, inspect your project dependencies using npm:

npm ls http-signature

Analyze the terminal output to locate any version of Http signature in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.0), your application is affected.

Note: The npm ls http-signature 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Http signature, 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

Affected versions of `http-signature` contain a vulnerability which can allow an attacker in a privileged network position to modify header names and change the meaning of the request, without requiring an updated signature. This problem occurs because vulnerable versions of `http-signature` sign the contents of headers, but not the header names. ## Proof of Concept Consider this to be the initial, untampered request: ```http POST /pay HTTP/1.1 Host: example.com Date: Thu, 05 Jan 2012 21:31:40 GMT X-Payment-Source: src@money.com X-Payment-Destination: dst@money.com Authorization: Signature keyId="Test",algorithm="rsa-sha256",headers="x-payment-source x-payment-destination" MDyO5tSvin5... ``` And the request is intercepted and tampered as follows: ```http X-Payment-Source: dst@money.com // Emails switched X-Payment-Destination: src@money.com Authorization: Signature keyId="Test",algorithm="rsa-sha256",headers="x-payment-destination x-payment-source" MDyO5tSvin5... ``` In the resulting responses, both requests would pass signature verification without issue. ``` src@money.com\n dst@money.com\n ``` ## Recommendation Update to version 0.10.0 or higher.
