CVE-2014-4705 — Huawei S9300 Firmware security vulnerability

High CVSS 7.8

Multiple heap-based buffer overflows in the eSap software platform in Huawei Campus S9300, S7700, S9700, S5300, S5700, S6300, and S6700 series switches; AR150, AR160, AR200, AR1200, AR2200, AR3200, AR530, NetEngine16EX, SRG1300, SRG2300, and SRG3300 series routers; and WLAN AC6005, AC6605, and ACU2 access controllers allow remote attackers to cause a denial of service (device restart) via a crafted length field in a packet.

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.
