CVE intelligence and bounded remediation

CVE-2018-15404 — Cisco Unified Computing System Director security vulnerability

Medium CVSS 6.5

A vulnerability in the web interface of Cisco Integrated Management Controller (IMC) Supervisor and Cisco UCS Director could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient restrictions on the size or total amount of resources allowed via the web interface. An attacker who has valid credentials for the application could exploit this vulnerability by sending a crafted or malformed HTTP request to the web interface. A successful exploit could allow the attacker to cause oversubscription of system resources or cause a component to become unresponsive, resulting in a DoS condition.

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.
