CVE-2017-16715: An Information Exposure issue was discovered in Moxa NPort 5110 Version 2.2, NPort 5110 Version 2.4, NPort...
An Information Exposure issue was discovered in Moxa NPort 5110 Version 2.2, NPort 5110 Version 2.4, NPort 5110 Version 2.6, NPort 5110 Version 2.7, NPort 5130 Version 3.7 and prior, and NPort 5150 Version 3.7 and prior. An attacker may be able to exploit a flaw in the handling of Ethernet frame padding that may allow for information exposure.
Security readout for executives and security teams
This CVE affects certain Moxa NPort serial device servers. A network attacker may be able to obtain unintended information because the device mishandles Ethernet frame padding. The listed CVSS score is high, and the issue matters most where these devices bridge industrial serial equipment onto IP networks. Exposure is likely limited to environments running the affected Moxa NPort 5110 versions 2.2, 2.4, 2.6, or 2.7, or NPort 5130/5150 version 3.7 and prior. Risk is higher if these devices are reachable from untrusted networks or flat OT networks. Treat as a high-priority OT exposure review if affected Moxa NPort devices are in production. The main business risk is unintended information leakage from infrastructure that may connect legacy serial equipment to IP networks. Prioritize inventory, network restriction, and vendor-guided remediation. Mitigation focus: Inventory Moxa NPort 5110, 5130, and 5150 devices and firmware versions.; Check the ICS-CERT advisory and Moxa guidance for vendor-approved updates or mitigations.; Remove affected devices from direct internet exposure..

CWE-200: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
