CVE-2021-3341Network attack vector

Unauthenticated file disclosure via HTTP path traversal

Published Jan 29, 2021 · Updated Aug 3, 2024

Path traversal in DxWebEngine in DH2i DxEnterprise and DxOdyssey before 20.0.219.0 allows remote attackers to read host files via HTTP. The public advisory does not identify the HTTP path field or disclose how DxWebEngine fails to constrain attacker-controlled paths to its intended directory. No authentication or user interaction is required, and the documented consequence is arbitrary host-file disclosure without file modification or service interruption.
