CVE-2017-6187 Disksavvy CVE debrief

CVE-2017-6187 is a critical buffer overflow in the built-in web server of DiskSavvy Enterprise 9.4.18. The NVD record rates it 9.8 (CVSS 3.0: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating a network-reachable issue that does not require privileges or user interaction and can impact confidentiality, integrity, and availability. Because the flaw is described as a long-URI GET-request overflow, exposed web interfaces should be treated as high priority until a vendor fix or compensating control is in place.

Who should care

Administrators and security teams responsible for DiskSavvy Enterprise deployments, especially systems running version 9.4.18 or exposing the built-in web server to any network beyond tightly controlled administration paths.

Technical summary

NVD identifies the vulnerability as a CWE-119 buffer overflow in DiskSavvy Enterprise 9.4.18’s built-in web server. The attack surface is remote and unauthenticated: a long URI in a GET request can trigger the overflow. The recorded CVSS vector (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects the possibility of arbitrary code execution or equivalent high-impact compromise. The CVE metadata includes third-party advisory and exploit references, but the supplied corpus does not provide vendor patch details or validated exploit behavior beyond the published description.

Defensive priority

Immediate if the built-in web server is reachable from untrusted networks; otherwise high priority for any internet-facing or broadly accessible deployment.

Recommended defensive actions

  • Identify all DiskSavvy Enterprise instances and confirm whether version 9.4.18 is installed.
  • Restrict or remove network access to the built-in web server, especially from untrusted networks.
  • Apply a vendor fix or upgrade path if one is available from the product vendor.
  • If the service is not required, disable the built-in web server until remediated.
  • Review logs and alerts for suspicious long-URI GET requests against DiskSavvy web endpoints.
  • Treat exposed systems as potentially high-risk and prioritize validation of patch status and exposure scope.

Evidence notes

All key claims are grounded in the supplied NVD/CVE metadata: published description, CVSS vector, and CWE-119 classification. The record’s reference list includes a SecurityFocus BID entry and an Exploit-DB entry, but this debrief does not rely on unverifiable details from those pages. Timing context: CVE published 2017-02-22 and NVD modified 2026-05-13; the modified date is record maintenance, not the vulnerability’s issue date.
