CVE-2020-37189: TaskCanvas 1.4.0 - 'Registration' Denial Of Service

TaskCanvas 1.4.0 contains a denial of service vulnerability in the registration code input field that allows attackers to crash the application. Attackers can generate a 1000-character buffer payload and paste it into the registration field to trigger an application crash.

Security readout for executives and security teams

Plain-English summary

TaskCanvas 1.4.0 can be crashed through its registration code input field. The reported impact is availability only: the application stops working, with no source evidence of data theft or privilege gain. Business urgency depends on whether TaskCanvas is used in operational workflows.

Executive priority

Prioritize if TaskCanvas supports important business tasks or is widely installed. This is not currently evidenced as actively exploited, but public exploit information exists and crashes can disrupt users.

Technical view

CVE-2020-37189 affects DigitalVolcano Software TaskCanvas 1.4.0. Sources describe a denial-of-service issue in the registration input field, mapped to CWE-120, with CVSS 3.1 score 7.5. ExploitDB and VulnCheck reference a crash condition. No vendor patch details are provided in the supplied sources.

Likely exposure

Exposure appears limited to environments running TaskCanvas 1.4.0. Confirm installed versions on endpoints. The supplied sources do not identify affected versions beyond 1.4.0 or provide server-side deployment details.

Exploitation context

A public ExploitDB entry exists, so proof-of-concept information is publicly available. CISA KEV is false in the supplied data, and no cited source states active exploitation in the wild.

Researcher notes

The source description is narrow: registration field denial of service in TaskCanvas 1.4.0. CVSS lists network, low complexity, no privileges, no user interaction, and high availability impact. Evidence does not establish code execution, persistence, or confidentiality impact.

Mitigation direction

  • Inventory endpoints for TaskCanvas installations and identify version 1.4.0.
  • Check DigitalVolcano guidance or downloads for a newer supported release.
  • Remove TaskCanvas where it is not business-critical.
  • Limit access to registration workflows to trusted users.
  • Prepare helpdesk guidance for application crashes affecting users.

Validation and detection

  • Confirm whether TaskCanvas 1.4.0 is installed in software inventory.
  • Review endpoint crash logs for TaskCanvas application failures.
  • Check vendor download and advisory sources for updated guidance.
  • Document business owners and workflows dependent on TaskCanvas.
  • Track remediation status for each affected endpoint.
