Huawei AR120-S V200R006C10, V200R007C00, AR1200 V200R006C10, V200R006C13, V200R007C00, V200R007C02, AR1200-S V200R006C10, V200R007C00, V200R008C20, AR150 V200R006C10, V200R007C00, V200R007C02, AR150-S V200R006C10, V200R007C00, AR160 V200R006C10, V200R006C12, V200R007C00S, V200R007C02, AR200 V200R006C10, V200R007C00, AR200-S V200R006C10, V200R007C00, AR2200 V200R006C10, V200R006C13, V200R006C16, V200R007C00, V200R007C02, AR2200-S V200R006C10, V200R007C00, V200R008C20, AR3200 V200R006C10, V200R006C11, V200R007C00, V200R007C02, AR3600 V200R006C10, V200R007C00, AR510 V200R006C12, V200R006C13, V200R006C15, V200R006C16, V200R006C17, V200R007C00, IPS Module V500R001C30, NIP6300 V500R001C30, NetEngine16EX V200R006C10, V200R007C00 have an insufficient input validation vulnerability. An unauthenticated, remote attacker may send crafted IKE V2 messages to the affected products. Due to the insufficient validation of the messages, successful exploit will cause invalid memory access and result in a denial of service on the affected products.

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.
