CVE intelligence and bounded remediation

CVE-2017-17223 — Huawei eSpace 7910 V200R003C30; eSpace 7950 V200R003C30; eSpace 8950 V200R003C00; V200R003C30 have a directory traversal vulnerability

High CVSS 8.8

Huawei eSpace 7910 V200R003C30; eSpace 7950 V200R003C30; eSpace 8950 V200R003C00; V200R003C30 have a directory traversal vulnerability. An authenticated, remote attacker can craft specific URL to the affected products. Due to insufficient verification of the URL, successful exploit will upload and download files and cause information leak and system crash.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

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

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
