CVE-2017-15323 — Huawei Dp300 Firmware security vulnerability

Medium CVSS 5.5

Huawei DP300 V500R002C00, NIP6600 V500R001C00, V500R001C20, V500R001C30, Secospace USG6500 V500R001C00, V500R001C20, V500R001C30, TE60 V100R001C01, V100R001C10, V100R003C00, V500R002C00, V600R006C00, TP3106 V100R001C06, V100R002C00, VP9660 V200R001C02, V200R001C30, V500R002C00, V500R002C10, ViewPoint 8660 V100R008C03, ViewPoint 9030 V100R011C02, V100R011C03, eCNS210_TD V100R004C10, eSpace U1981 V200R003C30 have a DoS vulnerability caused by memory exhaustion in some Huawei products. For lacking of adequate input validation, attackers can craft and send some malformed messages to the target device to exhaust the memory of the device and cause a Denial of Service (DoS).

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.
