CVE-2020-37234 Internetdownloadmanager CVE debrief

Who should care

Administrators and users running Internet Download Manager 6.38.12, especially on systems where untrusted local users can interact with the Scheduler dialog or related UI fields.

Technical summary

The supplied record identifies CWE-120 (classic buffer overflow) in the Scheduler component. The issue is triggered by oversized input, with the description stating that pasting data exceeding 5000 bytes into the "Open the following file when done" field can crash the application. The impact described in the record is denial of service rather than code execution.

Defensive priority

Moderate. This is a local denial-of-service flaw with CVSS 6.9 (Medium). Prioritize remediation on endpoints where Internet Download Manager is installed and where local user interaction is feasible or shared systems are in use.

Recommended defensive actions

• Confirm whether Internet Download Manager 6.38.12 is installed anywhere in the environment.
• Check vendor guidance and update to a fixed release if one is available.
• Restrict local access to affected workstations where practical, especially on shared-user systems.
• Monitor for repeated application crashes involving the Scheduler component or the specified dialog field.
• If patching is delayed, limit exposure by reducing access to the affected UI workflow and minimizing untrusted local input on impacted systems.
