CVE-2016-10666
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 · uneditedtomita-parser is a Node wrapper for Yandex Tomita Parser tomita-parser downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested resources with an attacker controlled copy if the attacker is on the network or positioned in between the user and the remote server.
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 tomita-parser Node.js wrapper downloads binary resources over plain HTTP instead of HTTPS, enabling man-in-the-middle attackers to intercept and replace the binaries with malicious code. Since the downloaded resources are executed by the parser, a successful MITM attack could result in remote code execution on the user's system.

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.
-
Check if tomita-parser is installedRun 'npm list tomita-parser' in your project directory, or inspect your package.json dependencies sectionAffected if The package appears in your installed dependencies or package.json
-
Identify the installed versionRun 'npm list tomita-parser' to see the installed version number, or check node_modules/tomita-parser/package.jsonAffected if The version is 0.0.3 or lower (any version up to and including 0.0.3)
-
Inspect the package download mechanismExamine the source code in node_modules/tomita-parser - look for URL strings that download binaries or resourcesAffected if The code contains HTTP URLs (not HTTPS) pointing to external domains for binary downloads
-
Check for recent network activity to download endpointsReview proxy logs, network traffic captures, or DNS/cache records for connections made by the tomita-parser package to external HTTP endpointsAffected if Plain HTTP connections were made to retrieve binary resources during package installation or execution
You are affected if tomita-parser version 0.0.3 or lower is installed and the package downloads binaries over plain HTTP.

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 dataUntil a secure version using HTTPS is released, avoid using this package in production environments. If immediate use is required, implement network-level TLS inspection or use a local proxy with signed/verified binary caches to mitigate the MITM risk.
