CVE-2016-10594
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedipip is a Node.js module to query geolocation information for an IP or domain, based on database by ipip.net. ipip downloads data resources over HTTP, which leaves it vulnerable to MITM attacks.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe ipip Node.js module downloads geolocation database resources from ipip.net over unencrypted HTTP connections, allowing an attacker on the network path to intercept and modify the downloaded data through Man-In-The-Middle attacks, potentially injecting malicious content into the application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ipip module usageSearch your project dependencies (package.json, package-lock.json, yarn.lock) for the 'ipip' module, or check node_modules for the ipip package directoryAffected if The ipip module is listed in dependencies or present in node_modules
-
Check for HTTP connections to ipip.netReview the ipip module source code in node_modules/ipip for network requests. Look for URLs using 'http://' instead of 'https://' pointing to ipip.net or related domainsAffected if The module makes network requests over unencrypted HTTP (http://) protocol
-
Monitor network trafficUse a network monitoring tool (tcpdump, Wireshark, or a proxy) to observe if your application establishes unencrypted HTTP connections to ipip.net or IP addresses resolving to that domainAffected if HTTP traffic to ipip.net is observed on port 80
-
Check for HTTPS URL configurationSearch project configuration files and ipip module initialization code for any HTTPS URL overrides or secure connection settings. Look for configuration options that might enable encrypted downloadsAffected if No HTTPS URL is configured and the module defaults to HTTP connections
Your environment is affected if the ipip Node.js module is installed and downloads geolocation data over unencrypted HTTP connections to ipip.net, allowing potential MITM injection of malicious content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace HTTP URLs with HTTPS and ensure proper TLS certificate validation is enforced when downloading ipip data resources, or migrate to a geolocation library that provides secure data delivery mechanisms.
