CVE-2020-37198: Duplicate Cleaner Pro 4 - Denial of Service

Duplicate Cleaner Pro 4.1.3 contains a denial of service vulnerability that allows attackers to crash the application by injecting an oversized buffer into the license key field. Attackers can generate a 6000-byte payload and paste it into the license activation field to trigger an application crash.

Security readout for executives and security teams

Plain-English summary

Duplicate Cleaner Pro 4 has a reported crash flaw in its license activation field. An oversized license key value can cause the application to stop working. The known impact is availability loss for this specific desktop application, not data theft or system takeover based on the provided sources.

Executive priority

Treat as a targeted application availability risk. Prioritize if Duplicate Cleaner Pro is used on business-critical workstations or operational workflows. Otherwise, handle through normal endpoint hygiene: inventory, remove unnecessary software, and update or replace unsupported versions.

Technical view

CVE-2020-37198 affects DigitalVolcano Duplicate Cleaner Pro 4, specifically described as 4.1.3. The issue is reported as CWE-121, triggered by an oversized buffer in the license key field, causing denial of service. Public exploit information exists on Exploit-DB, but the source bundle does not show confirmed active exploitation.

Likely exposure

Exposure is likely limited to endpoints where Duplicate Cleaner Pro 4 or 4.1.3 is installed and reachable by a user who can access the license activation field. The CVSS vector says network, no user interaction, but the narrative describes pasting input into a GUI field, so exposure mechanics are unclear.

Exploitation context

A public Exploit-DB entry is referenced, indicating proof-of-concept availability. The CVE is not marked as KEV, and no cited source confirms active exploitation. The business impact appears to be application disruption rather than broader host compromise, based on the provided evidence.

Researcher notes

The source data contains a practical inconsistency: CVSS lists network/no-user-interaction, while the description requires input into a license activation field. Do not assume remote exploitability without confirming original advisory details. No patch details are provided in the supplied sources.

Mitigation direction

  • Inventory endpoints for Duplicate Cleaner Pro 4, especially version 4.1.3.
  • Check DigitalVolcano guidance for supported versions, patches, or upgrade paths.
  • Remove or replace unsupported installations where the application is not business-critical.
  • Restrict use of affected systems to trusted users until vendor guidance is confirmed.
  • Avoid testing oversized license input on production systems.

Validation and detection

  • Confirm installed Duplicate Cleaner Pro version on managed endpoints.
  • Review application crash logs for repeated activation-field failures.
  • Compare findings against the CVE and VulnCheck advisory.
  • Verify whether a vendor-supported upgrade or replacement has been deployed.
  • Document exceptions where removal or upgrade is not immediately possible.
