CVE-2020-4207 — Ibm Iot Messagesight security vulnerability

Critical CVSS 9.8

IBM Watson IoT Message Gateway 2.0.0.x, 5.0.0.0, 5.0.0.1, and 5.0.0.2 is vulnerable to a buffer overflow, caused by improper bounds checking when handling a failed HTTP request with specific content in the headers. By sending a specially crafted HTTP request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service. IBM X-Force ID: 174972.

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.
