CVE-2022-4636Network attack vector

Unauthenticated file disclosure via path traversal

Published Jan 10, 2023 · Updated Jan 16, 2025

Path traversal in Black Box KVM firmware 3.4.31307 allows remote attackers to read credentials and other sensitive files. Black Box has not disclosed the affected endpoint or the exact path-validation error that permits local file inclusion. Network access is sufficient; no authentication or user interaction is required, and the documented consequence is disclosure without modification or service interruption.
