CVE-2023-7343
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 · uneditedHirschmann Industrial HiVision versions 05.0.00 through 08.3.01 prior to 08.3.02 contain an arbitrary code execution vulnerability triggered when an administrator opens a maliciously crafted project file. Successful exploitation allows the attacker to execute code in the context of the HiVision process.
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.

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.
-
Verify HiVision installationCheck system for Hirschmann HiVision application - look for HiVision in installed programs (Windows Add/Remove Programs, or Linux package manager if applicable)Affected if HiVision software is present on the system
-
Determine installed HiVision versionLocate HiVision version information - typically in application About dialog, installation directory, or registry keys under the HiVision install pathAffected if Unable to determine version or version is below 08.3.02
-
Compare version against fixed releaseCompare your installed version number to the fixed version 08.3.02 - versions prior to 08.3.02 are affectedAffected if Installed version is lower than 08.3.02 (e.g., 08.x.x before 08.3.02, or earlier major versions)
-
Identify project file handling exposureCheck if HiVision project files (.hiv or related project formats) are used or stored on the system - look for .hiv files in user directories, network shares, or project backup locationsAffected if Project files exist and could be opened by a user with HiVision installed
A system is affected if HiVision is installed with a version lower than 08.3.02 and users could potentially open project files from untrusted sources.

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.
dbcve · scopedUpdate to HiVision version 08.3.02 or later to remediate. Avoid opening untrusted project files and apply network segmentation to limit exposure.
Upgrade to HiVision version 08.3.02
- Obtain HiVision version 08.3.02 from the official Belden/Hirschmann vendor source (assets.belden.com or through your customer support channel)
- Backup all existing HiVision project files and configuration data
- Close any running HiVision instances and ensure no HiVision processes are active
- Install version 08.3.02 following the vendor's standard installation procedure
- Verify the installed version is 08.3.02 in the application About/Help section
- Test that legitimate project files open and function correctly after the upgrade
