Detailsinfo

A vulnerability was found in Autodesk AutoCAD, AutoCAD LT, AutoCAD Architecture, AutoCAD Electrical, AutoCAD Mechanical, AutoCAD MEP, AutoCAD Plant 3D, AutoCAD MAP 3D, Civil 3D and Advance Steel and classified as critical. This issue affects an unknown code block of the component DGN File Parser. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A maliciously crafted DGN file, when linked or imported into Autodesk AutoCAD, can force a Memory Corruption vulnerability. A malicious actor can leverage this vulnerability to execute arbitrary code in the context of the current process.

The advisory is shared at autodesk.com. The identification of this vulnerability is CVE-2025-5048 since 05/21/2025. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.
