CVE-2017-17166 — Huawei Dp300 Firmware security vulnerability

Medium CVSS 5.3

Huawei DP300 V500R002C00, Secospace USG6300 V500R001C00, V500R001C20, V500R001C30, V500R001C50, Secospace USG6500 V500R001C00, V500R001C20, V500R001C30, V500R001C50, Secospace USG6600 V500R001C00, V500R001C20, V500R001C30, V500R001C50, TP3206 V100R002C00, VP9660 V500R002C00, V500R002C10 have a resource exhaustion vulnerability. The software does not process certain field of H.323 message properly, a remote unauthenticated attacker could send crafted H.323 message to the device, successful exploit could cause certain service unavailable since the stack memory is exhausted.

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.
