Code execution via unchecked DWF object write
Published Aug 19, 2024 · Updated Aug 26, 2025
Out-of-bounds write in AdDwfPdk.dll in AutoCAD and affected AutoCAD-based products allows attackers to execute code via a crafted DWF file. During DWF parsing, the library fails to validate user-supplied data before writing past the end of an allocated object. Exploitation requires a user to open the file or visit a malicious page and can crash the process, corrupt data, or run code with that user's privileges.
