CVE-2017-4012
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 · uneditedPrivilege Escalation vulnerability in the server in McAfee Network Data Loss Prevention (NDLP) 9.3.x allows remote authenticated users to view confidential information via modification of the HTTP request.
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 confidenceA privilege escalation vulnerability in McAfee Network Data Loss Prevention (NDLP) 9.3.x allows remote authenticated users to view confidential information by modifying HTTP requests. This indicates insufficient server-side authorization validation after initial authentication, enabling users to access data outside their authorized scope.

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 McAfee NDLP installation and versionCheck the installed version of McAfee Network Data Loss Prevention on the system. This is typically available in the product's about or system information page within the NDLP management console, or via the installed programs list on the server.Affected if The installed version is 9.3.x or any version <= 9.3.0
-
Verify HTTP management interface accessibilityDetermine if the NDLP web-based management console is accessible over HTTP/HTTPS. Check if port 8443 or the default NDLP web interface port is open and reachable from the network.Affected if The NDLP management interface is accessible remotely and accepts authenticated user sessions
-
Review user role assignmentsExamine the authorization configuration within NDLP to identify user roles and their assigned permissions. Check if non-administrative users have access to the management console.Affected if Authenticated users with limited privileges can access the HTTP management interface
-
Check for server-side authorization enforcementInspect the NDLP configuration to determine whether server-side authorization validation is properly enforced for HTTP requests. This typically involves reviewing access control policies and verifying that privilege checks occur on the server for all user actions.Affected if The system relies primarily on client-side or initial authentication without validating authorization for each HTTP request
-
Audit access control configurationsReview the NDLP access control settings to confirm whether users are restricted to only the data and functions within their assigned scope. Look for evidence that users can potentially modify HTTP requests to access data outside their authorized boundaries.Affected if Access controls allow authenticated users to bypass scope restrictions via modified HTTP requests
A user is affected if McAfee NDLP version 9.3.x (specifically <= 9.3.0) is installed, the management interface is accessible to authenticated users, and server-side authorization validation is insufficient for HTTP requests.

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 dataImplement proper server-side authorization checks for all HTTP requests, enforce least-privilege access controls, and apply vendor patches if available. Restrict NDLP administrative access to only essential personnel.
