CVE intelligence and bounded remediation

CVE-2021-45460 — A vulnerability has been identified in SICAM PQ Analyzer (All versions < V3.18)

High CVSS 8.1

A vulnerability has been identified in SICAM PQ Analyzer (All versions < V3.18). A service is started by an unquoted registry entry. As there are spaces in this path, attackers with write privilege to those directories might be able to plant executables that will run in place of the legitimate process. Attackers might achieve persistence on the system ("backdoors") or cause a 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.
