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
Installation of the SonicOS SSLVPN NACagent 3.5 on the Windows operating system, an autorun value is created does not put the path in quotes, so if a malicious binary by an attacker within the parent path could allow code execution.

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

The SonicOS SSLVPN NACagent 3.5 installer creates a Windows autorun registry entry without quoting the executable path. This unquoted path vulnerability allows Windows to misinterpret paths containing spaces, potentially executing malicious binaries placed in parent directories instead of the intended application.

MitigationOrganizations should modify the affected autorun registry entry to enclose the executable path in quotes, ensuring proper path resolution and preventing arbitrary code execution via path injection.

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. Verify NACagent 3.5 is installed
    Check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'NACagent' or inspect the program files directory (commonly C:\Program Files\SonicWall\NACagent) for the nacagent.exe file. Use 'wmic product get name,version' or check Add/Remove Programs.
    Affected if The NACagent version 3.5 is present on the system
  2. Locate the autorun registry entry
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Look for a value named 'NACagent', 'NAC Agent', or similar SonicWall NAC-related entry.
    Affected if A registry autorun entry for NACagent exists in the Run key
  3. Inspect the executable path for unquoted spaces
    Examine the data value of the NACagent autorun entry. Identify whether the path to nacagent.exe contains spaces and is not enclosed in quotation marks (e.g., C:\Program Files\SonicWall\NACagent\nacagent.exe instead of "C:\Program Files\SonicWall\NACagent\nacagent.exe").
    Affected if The executable path contains unquoted spaces, making path injection possible

A user is affected if NACagent version 3.5 is installed and its autorun registry entry contains an unquoted executable path with spaces.
