Technical ContextAI · show details
This vulnerability is classified as XML External Entity (XXE) (CWE-611), which allows attackers to read arbitrary files or perform SSRF through XML processing. 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. Affected products include: Datakit Crosscadware, Luxion Keyshot, Siemens Solid Edge Se2020 Firmware, Siemens Solid Edge Se2021 Firmware.
