CVE-2016-10627
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 · uneditedscala-bin is a binary wrapper for Scala. scala-bin 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 binary with an attacker controlled binary 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 scala-bin package downloads Scala binary resources over unencrypted HTTP instead of HTTPS, allowing attackers on the network to perform man-in-the-middle attacks and substitute malicious binaries for the legitimate Scala binaries, potentially achieving remote code execution when users execute the downloaded content.

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 scala-bin package is installedRun 'npm list scala-bin' or check your project's node_modules directory for the scala-bin packageAffected if The scala-bin package is present in the project dependencies or node_modules
-
Determine the installed version of scala-binRun 'npm list scala-bin' or check package.json for the scala-bin version entry, then compare to 0.3.3Affected if The installed version is 0.3.3 or lower
-
Inspect package source for HTTP download URLsExamine the scala-bin package source code (typically in node_modules/scala-bin/) for HTTP:// URLs used to fetch Scala binaries, particularly in installation or download scriptsAffected if The package code contains unencrypted HTTP URLs pointing to Scala binary distribution servers
-
Check for binary download behaviorReview any scripts or code that execute during package installation or runtime that fetch external Scala binaries, noting the protocol usedAffected if The package fetches external Scala binaries over HTTP rather than HTTPS during installation or execution
You are affected if the scala-bin package version 0.3.3 or lower is installed and its code downloads Scala binaries over unencrypted HTTP URLs.

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 all HTTP download URLs with HTTPS and implement proper TLS certificate validation to ensure the authenticity of downloaded binaries. Consider adding cryptographic checksums or signatures for binary verification.
