CVE-2024-38465
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 · uneditedShenzhen Guoxin Synthesis image system before 8.3.0 allows username enumeration because of the response discrepancy of incorrect versus error.
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 confidenceThe Shenzhen Guoxin Synthesis image system before version 8.3.0 contains a username enumeration vulnerability in its authentication mechanism. The system returns different HTTP responses or error messages when a provided username does not exist versus when an authentication error occurs, allowing remote attackers to determine valid usernames through brute force or guessing.

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 version of Guoxinled Synthesis Image SystemCheck the system administration panel, About page, or consult system documentation for the version number. If command-line access is available, look for version information in the application binary, configuration files, or startup logs.Affected if The installed version is lower than 8.3.0
-
Locate the web authentication endpointIdentify the login page URL for the Guoxinled Synthesis Image System. This is typically found at paths such as /login, /admin/login, or /auth on the server hosting the application.Affected if The authentication endpoint is accessible over HTTP/HTTPS
-
Test authentication response for non-existent usernameSend an HTTP POST request to the login endpoint with a clearly invalid username (e.g., nonexistentuser123) and any password. Record the HTTP status code and any error message returned.Affected if The response indicates that the username does not exist or is invalid
-
Test authentication response for valid username with wrong passwordSend an HTTP POST request to the login endpoint with a known-valid username and an intentionally incorrect password. Record the HTTP status code and any error message returned.Affected if The response indicates that the password is incorrect or authentication failed
-
Compare authentication error responsesReview the responses from steps 3 and 4. Check for differences in HTTP status codes, error message text, response timing, or any other distinguishing factor between invalid username and incorrect password scenarios.Affected if The responses differ in a way that reveals whether the username is valid
You are affected if the Guoxinled Synthesis Image System version is below 8.3.0 AND the authentication endpoint returns distinguishable error messages for invalid usernames versus incorrect passwords.

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 data8.3.0
Upgrade to version 8.3.0 or later. If immediate patching is not possible, implement uniform error responses for all authentication failures (both invalid username and incorrect password) to prevent response-based enumeration.
