CVE-2021-38174Network attack vector

Application crash via improperly validated file

Published Sep 14, 2021 · Updated Aug 4, 2024

Improper input validation in SAP 3D Visual Enterprise Viewer 9 allows remote attackers to crash the application via a manipulated file. The viewer processes a file from an untrusted source without sufficient validation, but SAP has not disclosed the affected format, parser, or malformed field. A user must open the file; the denial of service lasts until the application is restarted, with no reported confidentiality or integrity impact.
