CVE-2021-27492

Status: ModifiedMedium (5.5)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
