CVE-2019-14242
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 · uneditedAn issue was discovered in Bitdefender products for Windows (Bitdefender Endpoint Security Tool versions prior to 6.6.8.115; and Bitdefender Antivirus Plus, Bitdefender Internet Security, and Bitdefender Total Security versions prior to 23.0.24.120) that can lead to local code injection. A local attacker with administrator privileges can create a malicious DLL file in %SystemRoot%\System32\ that will be executed with local user privileges.
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 confidenceA DLL hijacking vulnerability in Bitdefender products for Windows allows a local attacker with administrator privileges to place a malicious DLL in %SystemRoot%\System32\, which gets loaded and executed by Bitdefender components with local user privileges. This enables code injection and potential privilege persistence.

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 Bitdefender product and versionOpen Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*Bitdefender*"}' in PowerShell to list installed Bitdefender products with their version numbers.Affected if The installed version falls below 23.0.24.120 for consumer products (Antivirus Plus, Internet Security, Total Security) or below 6.6.8.115 for Bitdefender Endpoint Security Tool.
-
Confirm Bitdefender services are presentOpen Services (services.msc) and look for Bitdefender-related services such as 'Bitdefender Endpoint Security Agent', 'Bitdefender Antivirus', or check via command: 'Get-Service | Where-Object {$_.DisplayName -like "*Bitdefender*"}'Affected if Bitdefender services are running on the system, indicating the vulnerable software is active and could be exploited.
-
Verify user privileges on the systemCheck if standard or low-privilege users have access to the system. Run 'whoami /all' to see your current privileges and 'net user' to enumerate local users.Affected if An administrator-level account could place a malicious DLL in %SystemRoot%\System32\, which would then be loaded by Bitdefender components running under lower-privilege user contexts.
You are affected if a Bitdefender product (Antivirus Plus, Internet Security, Total Security, or Endpoint Security Tool) is installed with a version below the safe thresholds (23.0.24.120 or 6.6.8.115) and the system has multiple user accounts where an administrator could perform DLL hijacking.

From vendor data6.6.8.11523.0.24.120
Upgrade Bitdefender Endpoint Security Tool to version 6.6.8.115 or later, and consumer products (Antivirus Plus, Internet Security, Total Security) to version 23.0.24.120 or later. Apply the vendor patches through standard Bitdefender update mechanisms.
