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
Symantec Endpoint Protection, prior to 14.2 RU2, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

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 confidence

This is a privilege escalation vulnerability in Symantec Endpoint Protection (SEP) versions prior to 14.2 RU2. An attacker who already has limited access to the system could potentially exploit this vulnerability to gain elevated privileges, accessing resources and capabilities that should be restricted from standard users.

MitigationUpgrade Symantec Endpoint Protection to version 14.2 RU2 or later to remediate this vulnerability.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Confirm SEP installation
    Check if Symantec Endpoint Protection is installed by looking for the service 'Symantec Endpoint Protection' in Windows Services (services.msc) or checking for the installation directory typically at C:\Program Files\Symantec\Symantec Endpoint Protection\
    Affected if Symantec Endpoint Protection is not installed on the system
  2. Determine SEP version via command line
    Open a command prompt and run: smc -version. This command displays the installed version and build number of Symantec Endpoint Protection.
    Affected if The version displayed is 14.2 or earlier (any version prior to 14.2 RU2)
  3. Verify version via Windows registry
    Open Registry Editor (regedit) and navigate to HKLM\SOFTWARE\Symantec\Symantec Endpoint Protection\CurrentVersion. Look for the string value 'PRODUCT_VERSION' to read the exact version number.
    Affected if The PRODUCT_VERSION value is 14.2 or lower (for example, 14.0, 14.1, or 14.2)
  4. Confirm the exact RU2 patch level
    If the version shows 14.2, check for the specific RU2 build. In the same registry path, look for 'PRODUCT_VERSION' or 'LIVEUPDATE_VERSION' to determine if RU2 (14.2 RU2) is installed. Alternatively, in the SEP client GUI, go to Help > About Symantec Endpoint Protection to view the full version string including RU2.
    Affected if The version is 14.2 without RU2 patch (14.2 RU1, 14.2 base, or earlier)

The system is affected if Symantec Endpoint Protection version is 14.2 or earlier, meaning any version below 14.2 RU2.
