CVE-2014-8520
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 · uneditedMcAfee Network Data Loss Prevention (NDLP) before 9.3 allows remote attackers to obtain sensitive information via vectors related to open network ports.
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) versions prior to 9.3 contain an information disclosure vulnerability where remote attackers can obtain sensitive information through vectors involving open network ports. The vulnerability allows unauthorized access to potentially confidential data handled by the NDLP system.

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 NDLP versionCheck the McAfee Network Data Loss Prevention version through the product management console, system information panel, or command line interface used by the productAffected if The installed version matches 8.6, 9.2.0, 9.2.1, or any version less than or equal to 9.2.2
-
Enumerate open network ports on NDLP systemUse network scanning tools or system utilities to list all listening ports on the NDLP server, focusing on ports associated with NDLP services and management interfacesAffected if Open network ports are found that accept connections from untrusted network sources
-
Verify accessibility of NDLP management portsReview firewall rules and network configuration to determine if NDLP management or data handling ports are reachable from untrusted or external network segmentsAffected if Management or sensitive NDLP ports are exposed to networks outside the trusted internal environment
-
Review access logs for unauthorized access patternsExamine NDLP system logs, audit logs, and network access logs for connections from external or unexpected IP addresses to open NDLP portsAffected if Logs show connections from untrusted sources to NDLP open ports that may indicate exploitation attempts
A user is affected if their NDLP version is 8.6, 9.2.0, 9.2.1, or any version up to and including 9.2.2 AND the system has open network ports accessible to untrusted parties.

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 dataUpgrade McAfee Network Data Loss Prevention to version 9.3 or later to remediate this vulnerability. Additionally, restrict network access to NDLP management interfaces and monitor open ports for suspicious access patterns.
