CVE-2018-19240 — Trendnet Tv-Ip110Wn Firmware security vulnerability

Critical CVSS 9.8

Buffer overflow in network.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication).

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.
