CVE-2019-5982
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 · uneditedImproper download file verification vulnerability in VAIO Update 7.3.0.03150 and earlier allows remote attackers to conduct a man-in-the-middle attack via a malicous wireless LAN access point. A successful exploitation may result in a malicious file being downloaded/executed.
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 confidenceVAIO Update versions 7.3.0.03150 and earlier lack proper cryptographic verification of downloaded update files. When a user connects to a malicious wireless LAN access point, an attacker positioned as a man-in-the-middle can intercept and replace update files with malicious payloads before the application downloads and executes them.

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.
-
Confirm VAIO Update is installedLocate VAIO Update on the system via Windows Programs and Features, or query installed programs using PowerShell (Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like '*VAIO*Update*'}), or check common installation directories under Program FilesAffected if VAIO Update application exists on the system
-
Retrieve installed VAIO Update versionRight-click the VAIO Update executable (typically in Program Files/Sony/VAIO Update folder) and select Properties, then inspect the Version tab; alternatively, view version info in Programs and Features listAffected if Version displays as 7.3.0.03150 or any version number lower than this
-
Verify automatic update download is enabledOpen VAIO Update application and navigate to Settings or Preferences, or examine configuration files in the VAIO Update data directory for auto-download settingsAffected if Automatic download of updates is turned on and the vulnerable version is installed
-
Check network exposure historyReview system network connection history or logs to determine if VAIO Update has been used while connected to wireless networks (especially public or untrusted WLAN access points)Affected if The system has performed updates over wireless connections and runs the vulnerable version
The environment is affected if VAIO Update version 7.3.0.03150 or earlier is installed and automatic update downloads are enabled, particularly if the system uses or used wireless networks for updates.

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 dataUpdate VAIO Update to a version beyond 7.3.0.03150 to obtain the patched file verification mechanism. Avoid performing software updates over untrusted or public wireless networks until the patch is applied.
