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
Unquoted Windows search path vulnerability in the client in Symantec Endpoint Protection (SEP) 11.x before 11.0.7.4 and 12.x before 12.1.2 RU2 and Endpoint Protection Small Business Edition 12.x before 12.1.2 RU2 allows local users to gain privileges via a crafted program in the %SYSTEMDRIVE% directory.

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

Symantec Endpoint Protection client contains an unquoted Windows service path vulnerability. When the service executes, Windows searches for the service binary without proper path quoting, allowing a local attacker to place a malicious executable with the same name in the %SYSTEMDRIVE% directory. Windows will execute this attacker-controlled program instead of the legitimate service binary, resulting in privilege escalation from low-privileged user to SYSTEM level access.

MitigationUpdate Symantec Endpoint Protection to version 11.0.7.4, 12.1.2 RU2, or later which includes the patched service binary with proper path quoting. Alternatively, identify and quote the vulnerable service paths in the registry manually.

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. Check installed Symantec Endpoint Protection version
    Check the registry key HKLM\SOFTWARE\Symantec\SYMEP\Version or run 'wmic product where "name like '%Symantec Endpoint Protection%'" get version'
    Affected if The version matches 11.0.7.3 or earlier, or equals 11.0, 11.0.1, 11.0.2, 11.0.4, 11.0.3001, 11.0.6000, 11.0.6100, 11.0.6200, 11.0.6200.754, 11.0.6300, or 11.0.7000
  2. Identify SEP services in Windows registry
    Open Registry Editor and navigate to HKLM\SYSTEM\CurrentControlSet\Services, then look for service names containing 'Sep', 'Smc', or 'Symantec' such as SepMasterService, SmcService, or related services
    Affected if Any Symantec Endpoint Protection service exists on the system
  3. Check service ImagePath for unquoted paths with spaces
    In the services registry key from the previous step, examine the ImagePath value for each SEP service. If the path contains spaces and is not enclosed in double quotes, it is unquoted. For example: C:\Program Files\Symantec\Symantec Endpoint Protection\smc.exe is unquoted
    Affected if The ImagePath value contains a space and is not surrounded by quotation marks
  4. Verify executable location for path injection risk
    Identify the directory portion of the unquoted path (e.g., C:\Program Files\Symantec\Symantec Endpoint Protection\) and check if any executable files with the same name as the service binary exist in parent directories that Windows would search before the intended location. Also check the %SYSTEMDRIVE% root for files matching the service binary name
    Affected if A malicious executable with the service binary name exists in a directory Windows searches before the legitimate location, or in the system drive root

A system is affected if it runs a vulnerable version of Symantec Endpoint Protection (11.0 through 11.0.7.3) AND has any SEP service with an unquoted path in its ImagePath registry value, creating an opportunity for path injection privilege escalation.

From vendor data
Upgrade available Upgrade to a release after 11.0.7.3
Interim mitigation

Update Symantec Endpoint Protection to version 11.0.7.4, 12.1.2 RU2, or later which includes the patched service binary with proper path quoting. Alternatively, identify and quote the vulnerable service paths in the registry manually.
