CVE-2025-66838
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 · uneditedIn Aris v10.0.23.0.3587512 and before, the file upload functionality does not enforce any rate limiting or throttling, allowing users to upload files at an unrestricted rate. An attacker can exploit this behavior to rapidly upload a large volume of files, potentially leading to resource exhaustion such as disk space depletion, increased server load, or degraded performance
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 · high confidenceAris v10.0.23.0.3587512 and earlier versions lack rate limiting on the file upload functionality, allowing unlimited file uploads in rapid succession. Attackers can exploit this to upload excessive volumes of files, causing resource exhaustion through disk space depletion, increased server load, and service degradation.

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.
-
Identify Aris installation and versionLocate the Aris installation directory and check the version file or use the product's version information command. Compare the installed version number to the affected range: <= 10.0.23.0.3587512Affected if The installed version is 10.0.23.0.3587512 or any earlier version
-
Verify file upload functionality is accessibleDetermine if the file upload feature is exposed in the Aris web interface or API endpoints. Check if upload endpoints are reachable without authentication or accessible to the users in questionAffected if File upload endpoints are exposed and accessible without adequate access controls
-
Check for rate limiting configuration on upload endpointsInspect the web server configuration, load balancer settings, or application-level configuration for any rate limiting rules targeting the file upload URLs. Look for configurations related to upload request throttlingAffected if No rate limiting rules exist for file upload endpoints, or rate limiting is not configured
-
Inspect upload quota and throttling settingsReview Aris application configuration files and administrative settings for per-user upload quotas, file size limits, or request throttling parameters. Check both application and infrastructure layersAffected if No per-user upload quotas or throttling mechanisms are defined
-
Monitor for upload activity anomaliesReview server access logs and application audit logs for patterns of rapid, repeated upload requests from single IP addresses or user accounts. Check for unusual upload volumesAffected if Logs show excessive upload requests from single sources indicating lack of rate limiting
A defender is affected if Aris version 10.0.23.0.3587512 or earlier is running with accessible file upload functionality that lacks rate limiting or upload quotas configured.

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 dataImplement rate limiting, throttling, and per-user upload quotas on file upload endpoints to restrict upload frequency and volume, preventing resource exhaustion attacks.
