CVE-2023-4094
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 · uneditedARCONTE Aurea's authentication system, in its 1.5.0.0 version, could allow an attacker to make incorrect access requests in order to block each legitimate account and cause a denial of service. In addition, a resource has been identified that could allow circumventing the attempt limit set in the login form.
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 confidenceARCONTE Aurea 1.5.0.0 authentication system contains two related flaws: an attacker can make incorrect access requests to block legitimate accounts (account lockout DoS), and a resource exists that allows bypassing the login attempt limit set in the login form. Combined, these enable systematic account lockout attacks against 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 Arconte Aurea versionAccess the system administration panel, check the 'About' or 'System Information' section, or query the application version via command line if available (e.g., arconte --version). Compare the reported version number to 1.5.0.0.Affected if The installed version is exactly 1.5.0.0
-
Verify login attempt limit configurationNavigate to the authentication or security settings in the Arconte Aurea admin console. Look for 'Login Attempts', 'Account Lockout', or 'Rate Limiting' configuration options. Inspect whether a maximum number of failed login attempts is defined and enforced.Affected if No maximum failed login attempt limit is configured, or the limit can be bypassed via an alternate resource endpoint
-
Test for login attempt limit bypassSubmit multiple failed authentication requests through the standard login form, then attempt authentication through an alternate endpoint, API resource, or mobile interface (if available). Document whether additional login attempts are allowed beyond the defined limit.Affected if After exhausting the login attempt limit on one endpoint, additional authentication attempts succeed on another resource
-
Check account lockout notificationTrigger an account lockout by making incorrect access requests against a test account. Verify whether the affected user receives notification of the lockout or whether the lockout occurs without warning.Affected if Accounts become locked without user notification, indicating a DoS-prone lockout policy
The environment is affected if Fujitsu Arconte Aurea version 1.5.0.0 is running AND the authentication system either lacks enforced login attempt limits or allows those limits to be bypassed, enabling arbitrary account lockout.

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 proper account lockout policies with user notification, enforce stricter rate limiting on authentication endpoints, and remediate the attempt limit bypass vulnerability. Consider CAPTCHA or progressive delays after failed attempts.
