CVE-2023-2763

Code execution via unsafe DWG and DXF parsing

Published Jul 12, 2023 · Updated Sep 5, 2024

Memory-safety flaws in SOLIDWORKS Desktop 2021 through 2023 allow remote attackers to execute code through crafted DWG or DXF files. Published details identify unchecked length copies into fixed-length heap buffers and an unvalidated write beyond an allocated buffer; the use-after-free locus is undisclosed. Exploitation requires a user to open a malicious file or visit a malicious page and runs code in the current process.
