CVE-2018-11315 — The Local HTTP API in Radio Thermostat CT50 and CT80 1.04.84 and below products allows unauthorized access via a DNS rebinding attack

Medium CVSS 6.5

The Local HTTP API in Radio Thermostat CT50 and CT80 1.04.84 and below products allows unauthorized access via a DNS rebinding attack. This can result in remote device temperature control, as demonstrated by a tstat t_heat request that accesses a device purchased in the Spring of 2018, and sets a home's target temperature to 95 degrees Fahrenheit. This vulnerability might be described as an addendum to CVE-2013-4860.

Matched remediation archetype

General vulnerability remediation

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

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
