CVE intelligence and bounded remediation

CVE-2022-1677 — Redhat Openshift Container Platform security vulnerability

Medium CVSS 6.3

In OpenShift Container Platform, a user with permissions to create or modify Routes can craft a payload that inserts a malformed entry into one of the cluster router's HAProxy configuration files. This malformed entry can match any arbitrary hostname, or all hostnames in the cluster, and direct traffic to an arbitrary application within the cluster, including one under attacker control.

Matched remediation archetype

Resource exhaustion and denial of service

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

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
