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 · moderate confidenceBitdefender Total Security 2020 contains a vulnerability in how it handles Windows filesystem junctions before deletion. This improper handling can be exploited to trigger a denial of service on the affected system, likely due to the antivirus software entering a deadlock or crash state when processing malicious junction points.

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 Bitdefender Total Security 2020 is installedOpen Programs and Features or use command: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object {$_.DisplayName -like '*Bitdefender*Total Security*2020*'}Affected if The product is not listed in installed programs
-
Retrieve the installed version numberRun: (Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object {$_.DisplayName -like '*Bitdefender*Total Security*2020*'}).DisplayVersionAffected if Unable to retrieve version number or version is missing
-
Compare version against the affected rangeCompare the displayed version to 24.9. Versions below 24.9 (such as 24.0, 23.0, etc.) are within the affected range.Affected if Installed version is less than 24.9
-
Verify real-time protection is enabledOpen Bitdefender interface, go to Protection > Antiviral, and confirm 'File Shield' or real-time protection is turned ONAffected if File system protection is enabled and version is below 24.9
User is affected if Bitdefender Total Security 2020 version is below 24.9 and real-time file protection is enabled, as the junction handling flaw would be triggered during filesystem scans.
