CVE-2019-12804
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 · uneditedIn Hunesion i-oneNet version 3.0.7 ~ 3.0.53 and 4.0.4 ~ 4.0.16, due to the lack of update file integrity checking in the upgrade process, an attacker can craft malicious file and use it as an update.
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 i-oneNet software's upgrade process lacks integrity verification (e.g., cryptographic signature validation), allowing attackers to craft malicious update files that the system will accept and execute during the upgrade process.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 Hunesion I Onenet versionLocate the software version information in the application interface, system registry, or installation directory. Common locations include: About dialog, version info in control panel, or version file in the installation folder.Affected if The version falls within >= 3.0.7 and <= 3.0.53, OR within >= 4.0.4 and <= 4.0.16
-
Confirm upgrade feature is accessibleDetermine whether the upgrade or update functionality is available and enabled in the installation. Check if users have access to upgrade menus, commands, or automated update checks.Affected if The upgrade feature is present and can be invoked by users or automated processes
-
Inspect upgrade source configurationExamine how the system obtains update files. Look at configuration files, network settings, or update server settings that define where the system pulls updates from.Affected if The upgrade source is configured to accept updates from locations accessible to untrusted attackers, or source is not restricted to a trusted vendor server
-
Verify if signature validation existsAttempt to locate or trigger an upgrade and observe whether the system performs any cryptographic signature or integrity verification on the update files before execution.Affected if The system accepts and executes upgrade files without verifying cryptographic signatures or checksums, or no signature validation code is present in upgrade handling
A user is affected if Hunesion I Onenet is installed with a version between 3.0.7-3.0.53 or 4.0.4-4.0.16 and the upgrade functionality is accessible without signature verification.

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 dataRestrict update source access to trusted, controlled network paths until the vendor releases a patch implementing cryptographic signature verification for all updates.
