CVE-2017-14028 — Moxa Nport 5110 Firmware security vulnerability

High CVSS 7.5

A Resource Exhaustion 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 exhaust memory resources by sending a large amount of TCP SYN packets.

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
