CVE-2022-3864 — A vulnerability exists in the Relion update package signature validation

Medium CVSS 4.5

A vulnerability exists in the Relion update package signature validation. A tampered update package could cause the IED to restart. After restart the device is back to normal operation. An attacker could exploit the vulnerability by first gaining access to the system with security privileges and attempt to update the IED with a malicious update package. Successful exploitation of this vulnerability will cause the IED to restart, causing a temporary Denial of Service.

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.
