CVE-2020-1829 — Huawei Nip6800 Firmware security vulnerability

High CVSS 7.5

Huawei NIP6800 versions V500R001C30 and V500R001C60SPC500; and Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, and V500R001C60SPC500 have a vulnerability that the IPSec module handles a message improperly. Attackers can send specific message to cause double free memory. This may compromise normal service.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

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

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
