CVE-2025-5048 is a classic buffer overflow vulnerability (CWE-120) found in Autodesk AutoCAD versions 2023 to 2026. The flaw occurs during the processing of DGN files, a format commonly used for design data. When a maliciously crafted DGN file is linked or imported into AutoCAD, the software fails to properly check the size of input data before copying it into a buffer, leading to memory corruption. This memory corruption can be exploited by an attacker to execute arbitrary code with the privileges of the AutoCAD process. The attack vector requires the victim to open or import the malicious file, meaning user interaction is necessary. No privileges are required to trigger the vulnerability, but local access or file delivery through social engineering is needed. The vulnerability affects confidentiality, integrity, and availability, as arbitrary code execution could lead to data theft, system compromise, or denial of service. Although no exploits are currently known in the wild, the high CVSS score (7.8) reflects the significant risk posed by this vulnerability. Autodesk has not yet published patches, so organizations must monitor for updates and apply them promptly once available.

The impact of CVE-2025-5048 is substantial for organizations relying on Autodesk AutoCAD, especially in sectors like architecture, engineering, construction, and manufacturing. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain control over the AutoCAD process and potentially escalate privileges or move laterally within the network. This can result in theft or manipulation of sensitive design data, disruption of critical design workflows, and potential sabotage of engineering projects. The vulnerability compromises confidentiality by exposing proprietary design files, integrity by enabling unauthorized modifications, and availability by causing crashes or denial of service. Given AutoCAD's widespread use in critical infrastructure and industrial environments, exploitation could have cascading effects on operational continuity and intellectual property security.

To mitigate CVE-2025-5048, organizations should implement the following specific measures: 1) Restrict the import and linking of DGN files from untrusted or unknown sources by enforcing strict file validation policies and using sandboxed environments for file handling. 2) Educate users on the risks of opening unsolicited or suspicious design files, emphasizing the need for caution with email attachments and downloads. 3) Monitor Autodesk's security advisories closely and apply patches immediately upon release to remediate the vulnerability. 4) Employ application whitelisting and endpoint protection solutions that can detect and block anomalous behavior related to AutoCAD processes. 5) Use network segmentation to isolate systems running AutoCAD from less secure network zones, limiting potential lateral movement. 6) Implement robust backup and recovery procedures for design data to minimize impact in case of compromise. 7) Consider disabling or limiting DGN file support if not required for business operations until patches are available.
