Vulnerability Spotlight: Multiple code execution vulnerabilities in LibreCAD
Summary: Cisco Talos discovered three vulnerabilities in LibreCAD's libdfxfw open-source library, which reads and writes .dxf and .dwg files used as the primary vector graphics format in CAD software. TALOS-2021-1349 (CVE-2021-21898) and TALOS-2021-1350 (CVE-2021-21899) can trigger buffer overflows when a user opens a specially crafted DWG file, and TALOS-2021-1351 (CVE-2021-21900) does the same with a DXF file, in each case eventually allowing code execution on the victim machine.
What's compelling: The attack path is a file a designer opens in the normal course of work, and Talos confirmed the flaw could be exploited in libdxfrw version 2.2.0-rc2-19-ge02f3580 - so the exposure sits on the desks of the people who handle outside CAD files, not in a perimeter device.
