CVE-2014-8533
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 execute arbitrary code via vectors related to ICMP redirection.
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 a vulnerability that allows remote unauthenticated attackers to execute arbitrary code through malicious ICMP redirection packets. The ICMP redirection mechanism is exploited to inject and execute code on affected NDLP systems.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 versionAccess the NDLP management console or use the product's built-in version check command (typically via the ePO console or running 'ndlp --version' from the NDLP installation directory). Check the About/Version section in the NDLP web interface if available.Affected if The installed version is 8.6, 9.2.0, 9.2.1, or any version <= 9.2.2 (versions prior to 9.3)
-
Confirm NDLP is running as a network gateway or sensorReview the NDLP deployment configuration in the ePO console or NDLP management interface. Check if the system is configured in inline, bridge, or tap mode where it processes network traffic directly.Affected if NDLP is deployed in a mode where it processes ICMP traffic from untrusted network segments (inline/bridge/sensor modes)
-
Verify ICMP redirection handling is enabledCheck the NDLP network configuration settings for ICMP redirection handling or 'accept ICMP redirects' policy. This is typically found under Network Settings, Protocol Handling, or ICMP settings in the NDLP/ePO console.Affected if ICMP redirection packets from external or untrusted networks are allowed to be processed by NDLP (the setting is enabled or not explicitly disabled)
-
Assess network exposure to untrusted ICMP sourcesReview firewall rules and network segmentation around the NDLP appliance. Determine if the NDLP interface handling external/partner traffic can receive ICMP redirection packets from non-trusted hosts or only from explicitly trusted gateways.Affected if The NDLP sensor/gateway interface can receive ICMP redirect packets from hosts other than trusted network infrastructure devices (routers/gateways)
-
Check for recent ICMP-related events or anomaliesReview NDLP event logs, system logs, or ePO events for unusual ICMP redirection traffic, especially ICMP type 5 (redirect) packets, or spikes in ICMP traffic around the time frame of potential exploitation.Affected if There are logged ICMP redirection packets from unexpected sources or anomalous ICMP traffic patterns
A system is affected if it runs McAfee NDLP version 9.2.2 or earlier (including 8.6, 9.2.0, 9.2.1) and is configured to process network traffic where ICMP redirection packets from untrusted sources can reach the NDLP sensor.

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 NDLP to version 9.3 or later. As an interim defense-in-depth measure, filter or disable untrusted ICMP redirects at network perimeter devices and implement network segmentation to limit exposure.
