CVE-2016-10599
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 · uneditedsauce-connect is a Node.js wrapper over the SauceLabs SauceConnect.jar program for establishing a secure tunnel for intranet testing. sauce-connect 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 confidencesauce-connect, a Node.js wrapper for SauceLabs SauceConnect.jar, downloads binary resources over plain HTTP without any integrity verification. A network attacker performing a MITM attack can substitute the requested binary with a malicious one, potentially leading to remote code execution on the victim's machine.

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 if sauce-connect package is installedRun 'npm list sauce-connect' or check your package.json dependencies for the sauce-connect packageAffected if The package is listed in node_modules or package.json dependencies
-
Determine the installed sauce-connect versionRun 'npm list sauce-connect --depth=0' or inspect the version field in node_modules/sauce-connect/package.jsonAffected if The installed version is 0.1.1 or lower (any version <= 0.1.1)
-
Inspect download mechanism in the packageExamine the source code in node_modules/sauce-connect/ for HTTP URL usage in download functions, or review any configuration files that specify download endpointsAffected if The package retrieves binary resources over plain HTTP (http://) instead of HTTPS (https://)
-
Check for integrity verification on downloaded binariesReview the package source code for checksum, hash, or signature validation logic before executing downloaded binariesAffected if No integrity verification (such as SHA256, MD5, or signature checks) is performed on downloaded binaries before execution
You are affected if sauce-connect version 0.1.1 or lower is installed and the package downloads binaries over HTTP without any integrity verification.

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 download URLs with HTTPS and implement cryptographic checksum or signature verification for all downloaded binaries before execution.
