CVE-2020-37201: NetShareWatcher 1.5.8.0 - 'Name' Denial Of Service

NetShareWatcher 1.5.8.0 contains a buffer overflow vulnerability in the registration name input that allows attackers to crash the application. Attackers can generate a 1000-character payload and paste it into the 'Name' field to trigger an application crash.

Analyst readout for executives and security teams

Plain-English summary

NetShareWatcher 1.5.8.0 can be crashed through an overlong value in the registration “Name” field. The known impact is denial of service to the application, not data theft or remote code execution based on provided sources. Public exploit information exists, so teams using this exact version should treat remediation as time-sensitive.

Executive priority

Prioritize if NetShareWatcher 1.5.8.0 is used in operations or monitoring workflows where downtime matters. The issue is availability-focused, but public exploit information lowers the barrier for disruption. If the product is absent, no action beyond recordkeeping is needed.

Technical view

CVE-2020-37201 is a CWE-120 buffer overflow in Nsasoft Nsauditor NetShareWatcher 1.5.8.0. The CVSS 3.1 score is 7.5, with availability impact rated high and confidentiality/integrity impact none. The described trigger is malformed registration-name input causing application crash. Sources do not identify a patched version.

Likely exposure

Exposure appears limited to environments running Nsasoft Nsauditor NetShareWatcher version 1.5.8.0. The source bundle does not show affected CPEs, deployment prevalence, or whether the vulnerable input is reachable remotely in typical installations.

Exploitation context

The CVE is not listed as KEV in the provided data. ExploitDB is cited, indicating public exploit information exists. Provided sources support application crash denial of service, but do not support claims of active exploitation, privilege escalation, or code execution.

Researcher notes

Evidence is narrow: one affected version, denial-of-service behavior, CVSS 7.5, CWE-120, and public exploit reference. The provided sources do not name a fixed version, confirm active exploitation, or demonstrate impact beyond crashing the application. Avoid broad product-family assumptions without additional vendor confirmation.

Mitigation direction

  • Inventory systems for NetShareWatcher 1.5.8.0.
  • Check Nsasoft/vendor guidance for an update or supported replacement.
  • Restrict access to registration or configuration interfaces where feasible.
  • Remove or replace unsupported installations if no vendor fix is available.
  • Monitor affected systems for repeated application crashes.

Validation and detection

  • Confirm installed product name and version.
  • Review crash logs for NetShareWatcher application failures.
  • Verify whether public-facing or shared systems expose the vulnerable workflow.
  • Check vendor and advisory pages for updated remediation information.
  • Document compensating controls if no patch is available.
