CVE-2020-37234: Internet Download Manager 6.38.12 Scheduler Buffer Overflow
Internet Download Manager 6.38.12 contains a buffer overflow vulnerability in the Scheduler component that allows local attackers to crash the application by supplying oversized input. Attackers can paste malicious data exceeding 5000 bytes into the 'Open the following file when done' field to trigger a denial of service condition.
Security readout for executives and security teams
CVE-2020-37234 is a local denial-of-service issue in Internet Download Manager 6.38.12. A malformed oversized Scheduler value can crash the application. The known impact is loss of application availability, not confirmed system takeover or data theft. Treat this as moderate endpoint software risk where IDM is installed. Exposure appears limited to endpoints running Internet Download Manager 6.38.12. The source bundle does not identify other affected versions, server-side exposure, cloud exposure, or remote network attackability. Local access to the endpoint is the relevant access condition. Prioritize remediation where IDM is present on shared, operational, or high-availability workstations. This is not currently supported as a remote compromise issue, but it can disrupt endpoint productivity and indicates outdated third-party software hygiene. Mitigation focus: Inventory endpoints for Internet Download Manager 6.38.12.; Check vendor and advisory pages for fixed versions or official guidance.; Update or remove IDM where business use is not required..
