CVE-2023-4096
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 · uneditedWeak password recovery mechanism vulnerability in Fujitsu Arconte Áurea version 1.5.0.0, which exploitation could allow an attacker to perform a brute force attack on the emailed PIN number in order to change the password of a legitimate user.
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 confidenceWeak password recovery mechanism in Fujitsu Arconte Áurea 1.5.0.0 allows attackers to brute force the emailed PIN number to change legitimate user passwords. The PIN lacks sufficient complexity or rate limiting protections.

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 Fujitsu Arconte Áurea is installedCheck the installed software inventory or run a product-specific query to identify if Fujitsu Arconte Áurea is present in the environmentAffected if The product is installed and running
-
Identify the exact version numberUse the product's built-in version check, about dialog, or system information panel to determine the installed version of Fujitsu Arconte ÁureaAffected if The installed version is exactly 1.5.0.0
-
Locate the password recovery endpointAccess the application's login page and locate the 'forgot password' or password reset functionality to confirm the PIN-based recovery mechanism existsAffected if The password reset feature uses a PIN code sent via email
-
Verify rate limiting on PIN submissionAttempt multiple rapid PIN submissions to the password reset endpoint to observe if the application throttles or blocks repeated attemptsAffected if No rate limiting is enforced and unlimited PIN attempts can be made
-
Check PIN complexity requirementsReview the password reset workflow or application configuration to determine if the PIN meets minimum complexity standards (length, character variety)Affected if The PIN is short, uses only digits, or lacks sufficient complexity
If Fujitsu Arconte Áurea version 1.5.0.0 is running with the PIN-based password reset feature exposed and no rate limiting or PIN complexity requirements are enforced, the environment is affected by this vulnerability.

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 account lockout policies, increase PIN complexity and length, add rate limiting or CAPTCHA to prevent automated PIN guessing, and consider adding multi-factor authentication to the password reset process.
