In 2345 Security Guard 3.7, the driver file (2345NsProtect.sys, X64 version) allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of not validating input values from IOCTL 0x80002019.

Security readout for executives and security teams

Plain-English summary

CVE-2018-11035 is a local vulnerability in the x64 2345NsProtect.sys driver shipped with 2345 Security Guard 3.7. A local user could crash the Windows system with a blue screen, creating downtime. The sources do not confirm remote exposure, active exploitation, a vendor fix, or specific impact beyond denial of service.

Executive priority

Treat this as a targeted endpoint stability risk, not a confirmed remote breach issue. Prioritize validation first, then remove or update affected installations, especially on operationally important systems where a local crash could disrupt service or support workflows.

Technical view

The CVE describes improper input validation in 2345NsProtect.sys for IOCTL 0x80002019. The documented impact is local denial of service through BSOD, with only unspecified possible additional impact. Public metadata does not provide CVSS, CWE, CPE, patch status, or detailed affected-platform boundaries.

Likely exposure

Likely limited to Windows endpoints running 2345 Security Guard 3.7 with the x64 2345NsProtect.sys driver installed and loaded. Exposure requires local user access according to the CVE description. Asset inventories should confirm whether this product and driver exist in the environment.

Exploitation context

The CVE is not listed as KEV in the provided bundle, and the sources do not support active exploitation claims. A public PoC repository is referenced, but the available CVE summary only supports local denial-of-service risk, not remote compromise or confirmed privilege escalation.

Researcher notes

Evidence is sparse. The useful technical signal is the vulnerable x64 driver and IOCTL 0x80002019 input-validation flaw. Do not assume privilege escalation or remote exploitability from the current public metadata. Further analysis should verify driver versions, product packaging, and any vendor remediation history.

Mitigation direction

  • Check vendor guidance for fixed versions or recommended removal steps.
  • Upgrade, replace, or remove 2345 Security Guard 3.7 where business need is absent.
  • Restrict local interactive access on affected systems to trusted users only.
  • Prioritize remediation for shared workstations, kiosks, and high-availability endpoints.
  • Monitor affected hosts for unexpected BSOD or driver-related crash patterns.

Validation and detection

  • Inventory endpoints for 2345 Security Guard 3.7 installations.
  • Confirm whether 2345NsProtect.sys x64 is present and loaded.
  • Review endpoint crash telemetry for BSODs tied to this driver.
  • Check vendor release notes or advisories for a patched driver version.
  • Document compensating controls where upgrade or removal is not immediately possible.
