CVE-2016-10635
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 · uneditedbroccoli-closure is a Closure compiler plugin for Broccoli. broccoli-closure before 1.3.1 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 confidencebroccoli-closure before version 1.3.1 downloads Closure compiler binary resources over unencrypted HTTP instead of HTTPS, allowing a man-in-the-middle attacker to intercept and replace the binary with a malicious payload, potentially achieving remote code execution on the build 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.
-
Locate broccoli-closure in your project dependenciesInspect your project's package.json file and look for broccoli-closure in the dependencies or devDependencies sectionAffected if broccoli-closure is listed as a dependency
-
Identify the installed version of broccoli-closureRun 'npm list broccoli-closure' in your project directory, or check the package-lock.json file for the broccoli-closure entry to find the installed version numberAffected if The installed version is less than 1.3.1 (for example, 1.3.0, 1.2.0, etc.)
-
Verify the download mechanism being usedExamine the node_modules/broccoli-closure/index.js or lib files to see if HTTP (non-SSL) URLs are used when fetching Closure compiler binariesAffected if HTTP URLs (not HTTPS) are present in the download code
You are affected if broccoli-closure is installed with a version prior to 1.3.1 and your build process downloads Closure compiler binaries over unencrypted 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 data1.3.1
Update broccoli-closure to version 1.3.1 or later, which uses HTTPS for downloading binary resources. Verify the update through full build testing to ensure the patched version functions correctly.
