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 · unedited
An unquoted search path or element vulnerability has been reported to affect NetBak Replicator. If a local attacker gains a user account, they can then exploit the vulnerability to execute unauthorized code or commands. We have already fixed the vulnerability in the following version: NetBak Replicator 4.5.15.0807 and later

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 confidence

NetBak Replicator contains an unquoted service path vulnerability where the executable path includes spaces without proper quotation marks. A local attacker with a user account can place a malicious executable in an intermediate directory along the path, which Windows will execute when the service starts, achieving privilege escalation to execute unauthorized code or commands.

MitigationUpgrade NetBak Replicator to version 4.5.15.0807 or later to obtain the patched binaries with properly quoted service paths.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate NetBak Replicator service
    Open Command Prompt or PowerShell and run: sc query NetBak Replicator or Get-Service -Name *NetBak*
    Affected if No service found means not installed or differently named - you are not affected
  2. Query the service executable path
    Run: sc qc "NetBak Replicator" (use the exact service name from step 1). Check the BINARY_PATH_NAME field for the executable path.
    Affected if If the BINARY_PATH_NAME contains spaces and is NOT enclosed in quotation marks, you are vulnerable to CVE-2025-57714
  3. Inspect path for unquoted spaces
    Examine the BINARY_PATH_NAME from step 2. Look for directory names with spaces that are not surrounded by double quotes, for example: C:\Program Files\NetBak\Replicator\netbak.exe would be unquoted.
    Affected if Any directory in the path with spaces that lacks surrounding quotes indicates the unquoted path vulnerability is present
  4. Check installed NetBak Replicator version
    Locate the NetBak Replicator installation directory (commonly in Program Files) and check the file version of the main executable, or look in Programs and Features for the installed version.
    Affected if Version is >= 4.5.0.0209 and < 4.5.15.0807 means the version range is affected; version >= 4.5.15.0807 means it is patched

You are affected by CVE-2025-57714 if NetBak Replicator is installed, the service BINARY_PATH_NAME contains unquoted spaces, and the installed version is below 4.5.15.0807.
