CVE-2024-5313 — CWE-668: Exposure of the Resource Wrong Sphere vulnerability exists that exposes a SSH interface over the product network interface

Medium CVSS 6.5

CWE-668: Exposure of the Resource Wrong Sphere vulnerability exists that exposes a SSH interface over the product network interface. This does not allow to directly exploit the product or make any unintended operation as the SSH interface access is protected by an authentication mechanism. Impacts are limited to port scanning and fingerprinting activities as well as attempts to perform a potential denial of service attack on the exposed SSH interface.

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.
