CVE-2017-4016
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 · uneditedWeb Server method disclosure in the server in McAfee Network Data Loss Prevention (NDLP) 9.3.x allows remote attackers to exploit and find another hole via HTTP response header.
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 · moderate confidenceMcAfee Network Data Loss Prevention (NDLP) 9.3.x discloses HTTP methods through server response headers, allowing remote attackers to enumerate available HTTP methods and potentially discover additional attack vectors. This information disclosure enables attackers to map the API surface and identify vulnerable endpoints.

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 installed McAfee NDLP versionLocate the NDLP installation and retrieve the version number through the product's about panel, installer properties, or system information interface. On Windows, check Add/Remove Programs or the installation directory for version files.Affected if The installed version is 9.3.x or lower (specifically 9.3.0 or below)
-
Confirm NDLP web server component is accessibleDetermine if the NDLP management interface or any web-based component is exposed on your network. Identify the IP address or hostname where the NDLP web server listens.Affected if The NDLP web interface is reachable from a network perspective, even if behind authentication
-
Test HTTP response headers for method disclosureSend HTTP requests (OPTIONS, GET, HEAD, etc.) to the NDLP web server endpoint and capture the response headers. Inspect all headers returned, particularly looking for headers that list or suggest available HTTP methods.Affected if Response headers explicitly list allowed HTTP methods (such as an Allow header) or contain method-related information that should not be disclosed
-
Compare headers against hardened configurationReview the HTTP response headers against documented expected headers for NDLP 9.3.x. Any unexpected disclosure of HTTP methods, verbs, or API capabilities indicates the vulnerability may be present.Affected if Headers reveal HTTP methods or verbs that should be suppressed or hidden
You are affected if running McAfee NDLP version 9.3.0 or lower AND the web server response headers expose available HTTP methods to unauthenticated or authenticated users.

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 dataConfigure the web server to suppress or obscure method-related information in HTTP response headers. Apply vendor-provided patches for NDLP 9.3.x and ensure the latest supported version is deployed.
