# CVE-2021-27492: When opening a specially crafted 3DXML file, the application containing Datakit Software libraries CatiaV5\_3dRead, CatiaV6\_3dRead, Step3dRea

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2021-05-27 · Updated: 2024-08-03

## Affected

- n/a Datakit Software libraries embedded in Luxion KeyShot software: version range not reported

## Description

When opening a specially crafted 3DXML file, the application containing Datakit Software libraries CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr modules in KeyShot Versions v10.1 and prior could disclose arbitrary files to remote attackers. This is because of the passing of specially crafted content to the underlying XML parser without taking proper restrictions such as prohibiting an external DTD.

## What to do

- Check your stack: if you ship or depend on n/a Datakit Software libraries embedded in Luxion KeyShot software, no fixed version is listed yet; follow the vendor advisory per the references below.
