CVE-2017-17150 — Huawei Dp300 Firmware security vulnerability

Medium CVSS 5.5

Timergrp module in Huawei DP300 V500R002C00; RP200 V500R002C00; V600R006C00; TE30 V100R001C10; V500R002C00; V600R006C00; TE40 V500R002C00; V600R006C00; TE50 V500R002C00; V600R006C00; TE60 V100R001C10; V500R002C00; V600R006C00 have an DoS vulnerability due to insufficient validation of the parameter. An authenticated local attacker may call a special API with special parameter, which cause an infinite loop. Successful exploit of this vulnerability can allow an attacker to launch DOS attack.

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.
