CVE-2019-1667 — Cisco Hyperflex Hx Data Platform security vulnerability

Medium CVSS 4

A vulnerability in the Graphite interface of Cisco HyperFlex software could allow an authenticated, local attacker to write arbitrary data to the Graphite interface. The vulnerability is due to insufficient authorization controls. An attacker could exploit this vulnerability by connecting to the Graphite service and sending arbitrary data. A successful exploit could allow the attacker to write arbitrary data to Graphite, which could result in invalid statistics being presented in the interface. Versions prior to 3.5(2a) are affected.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

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

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
