CVE-2018-16307 — An "Out-of-band resource load" issue was discovered on Xiaomi MIWiFi Xiaomi_55DD Version 2.8.50 devices

High CVSS 7.5

An "Out-of-band resource load" issue was discovered on Xiaomi MIWiFi Xiaomi_55DD Version 2.8.50 devices. It is possible to induce the application to retrieve the contents of an arbitrary external URL and return those contents in its own response. If a domain name (containing a random string) is used in the HTTP Host header, the application performs an HTTP request to the specified domain. The response from that request is then included in the application's own response.

Matched remediation archetype

Information disclosure and sensitive data exposure

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

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
