CVE-2023-32657
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 · uneditedWeintek Weincloud v0.13.6 could allow an attacker to efficiently develop a brute force attack on credentials with authentication hints from error message responses.
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 confidenceWeintek Weincloud v0.13.6 contains an information disclosure vulnerability where authentication error messages reveal hints that enable attackers to conduct efficient credential brute force attacks. The error responses provide different feedback for valid vs invalid usernames, or expose password policy hints, allowing attackers to narrow their attack scope.

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 the installed Weincloud versionCheck the application version through its web interface, configuration files, or software inventory. Look for version information in the product's about page, system settings, or installed packages.Affected if The installed version is exactly 0.13.6
-
Test authentication error response for invalid usernameSubmit a login request with a clearly invalid or non-existent username and capture the exact error message returned by the server.Affected if The error message indicates the username does not exist or provides different feedback than when a valid username is used with a wrong password
-
Test authentication error response for valid username with wrong passwordSubmit a login request using a valid username (or one you control) with an incorrect password and capture the exact error message returned.Affected if The error message differs from the invalid username case, revealing that the username is valid
-
Check for password policy hints in error messagesSubmit various failed login attempts and examine all error messages for any mention of password requirements, complexity rules, or account lockout information.Affected if Any error message reveals password complexity rules, minimum length, character requirements, or hints about account status
A system is affected if it is running Weincloud version 0.13.6 AND the authentication error messages provide different feedback for valid vs invalid usernames OR expose password policy hints.

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 generic authentication error messages that do not reveal whether credentials are valid or provide password hints. Additionally, implement rate limiting and account lockout mechanisms to mitigate brute force attempts.
