CVE-2024-53647
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 · uneditedTrend Micro ID Security, version 3.0 and below contains a vulnerability that could allow an attacker to send an unlimited number of email verification requests without any restriction, potentially leading to abuse or denial of service.
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 confidenceTrend Micro ID Security v3.0 and below lacks rate limiting on its email verification endpoint, allowing an unauthenticated attacker to programmatically submit unlimited email verification requests. This can exhaust server resources, cause denial of service, and result in emailbombing attacks against targeted users.

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 installed Trend Micro ID Security versionCheck the application version through the installed software inventory, about dialog, or version file in the installation directoryAffected if The installed version is 3.0 or lower (any version <= 3.0)
-
Confirm email verification feature is enabledLocate the email verification or email lookup feature in the application settings or configuration panel and verify it is activeAffected if The email verification endpoint is exposed and enabled in the application
-
Check for rate limiting configurationInspect the application configuration files, web server settings, or API gateway settings for rate limiting rules applied to the email verification endpointAffected if No rate limiting rules exist (e.g., no limit on requests per IP per minute)
-
Review request logs for abuse indicatorsExamine application access logs or security logs for patterns of repeated email verification requests from single IP addressesAffected if Logs show excessive verification requests from the same source without throttling
-
Verify CAPTCHA or challenge mechanismCheck if the email verification endpoint has CAPTCHA, proof-of-work, or similar challenge mechanisms configuredAffected if No challenge mechanism is present on the verification endpoint
A defender is affected if Trend Micro ID Security version 3.0 or below is installed with the email verification endpoint enabled and no rate limiting or challenge mechanism is configured.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedImplement rate limiting on the email verification endpoint (e.g., 3-5 requests per IP per minute), add CAPTCHA or proof-of-work challenges for repeated requests, and enable request logging to detect abuse patterns.
Version 3.1 or later (latest available version)
- Upgrade Trend Micro ID Security to the latest available version from the official Trend Micro website or your application's update mechanism
- After upgrading, verify that email verification requests are now subject to rate limiting or throttling controls
