CVE-2025-61303
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHatching Triage Sandbox Windows 10 build 2004 (2025-08-14) and Windows 10 LTSC 2021(2025-08-14) contains a vulnerability in its Windows behavioral analysis engine that allows a submitted malware sample to evade detection and cause denial-of-analysis. The vulnerability is triggered when a sample recursively spawns a large number of child processes, generating high log volume and exhausting system resources. As a result, key malicious behavior, including PowerShell execution and reverse shell activity, may not be recorded or reported, misleading analysts and compromising the integrity and availability of sandboxed analysis results.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Hatching Triage Sandbox Windows behavioral analysis engine contains a resource exhaustion vulnerability where malware samples that recursively spawn large numbers of child processes generate excessive log volume, exhausting system resources. This causes key malicious behaviors such as PowerShell execution and reverse shell activity to go unrecorded, enabling evasion and compromising analysis integrity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Hatching Triage Sandbox Windows is in useReview your analysis environment to verify that Hatching Triage Sandbox is deployed for Windows behavioral analysis. Check installation directories, documentation, or running services for 'triage' or 'hatching' indicators.Affected if Hatching Triage Sandbox Windows is deployed as your malware analysis engine
-
Check for process count limitsInspect the Triage Sandbox configuration files for any settings controlling maximum child processes per analysis session. Look for parameters like 'max_processes', 'process_limit', or similar resource constraints in the configuration directory.Affected if No process count limits are configured and recursive process spawning is allowed unchecked
-
Check for log throttling controlsReview the logging configuration to determine if log volume throttling, rate limiting, or log rotation settings are enabled to prevent resource exhaustion from excessive log generation.Affected if Log throttling or volume controls are disabled or absent in the configuration
-
Check for resource quotasExamine system resource quotas or analysis session limits (CPU, memory, disk I/O) that may constrain an individual malware sample's resource consumption during dynamic analysis.Affected if No resource quotas are enforced on analysis sessions
-
Compare installed version to vendor guidanceDetermine the installed Triage Sandbox version by checking the product's about page, version file, or running 'triage --version' if available. Compare against any official vendor security advisories for CVE-2025-61303.Affected if The installed version has not been patched to address the resource exhaustion vulnerability
A user is affected if they run Hatching Triage Sandbox for Windows analysis without process count limits, log throttling, or resource quotas in place, and the installed version lacks the vendor patch for CVE-2025-61303.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-provided patches to the Triage Sandbox. Implement compensating controls such as process count limits, log throttling, and resource quotas in the analysis engine until patches are deployed.
