CVE-2025-5047 is a vulnerability identified in Autodesk AutoCAD versions 2023 through 2026, stemming from the use of an uninitialized variable (CWE-457) during the parsing of DGN files, a common CAD file format. When AutoCAD processes a maliciously crafted DGN file, the uninitialized variable can lead to undefined behavior, which an attacker can exploit to cause a denial of service (application crash), unauthorized disclosure of sensitive information, or execute arbitrary code within the context of the AutoCAD process. The vulnerability requires the victim to open a malicious DGN file, implying user interaction is necessary. The CVSS v3.1 base score of 7.8 indicates a high severity rating, with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impacts on confidentiality, integrity, and availability are all high (C:H/I:H/A:H). No patches or exploits are currently publicly available, but the vulnerability poses a significant risk due to AutoCAD's extensive use in critical industries such as engineering, construction, and manufacturing. The flaw highlights a common software development issue where uninitialized variables can lead to memory corruption and security breaches. Autodesk and users should monitor for official patches and advisories to remediate this issue promptly.

The impact of CVE-2025-5047 is substantial for organizations using Autodesk AutoCAD, especially those handling sensitive design and engineering data. Successful exploitation can lead to application crashes, disrupting workflows and causing potential data loss. More critically, attackers can execute arbitrary code, potentially gaining control over the affected system with the privileges of the AutoCAD process. This could allow lateral movement within corporate networks, theft of intellectual property, or sabotage of design files. The confidentiality of sensitive project data is at risk, which could have severe consequences in industries like aerospace, defense, infrastructure, and manufacturing. The availability of AutoCAD services may be compromised, affecting productivity and project timelines. Given the widespread adoption of AutoCAD globally, the vulnerability could be leveraged in targeted attacks against high-value organizations or in broader campaigns exploiting unpatched systems. The requirement for user interaction limits remote exploitation but does not eliminate risk, as social engineering or phishing could be used to deliver malicious files.

To mitigate CVE-2025-5047, organizations should implement the following specific measures: 1) Monitor Autodesk’s official channels for patches and apply them immediately upon release to address the uninitialized variable flaw. 2) Restrict the acceptance and opening of DGN files from untrusted or unknown sources through email filtering, endpoint controls, and user training to reduce the risk of malicious file execution. 3) Employ application whitelisting and sandboxing techniques to isolate AutoCAD processes and limit the impact of potential exploitation. 4) Use network segmentation to separate design workstations from critical infrastructure and sensitive data repositories, minimizing lateral movement opportunities. 5) Implement robust endpoint detection and response (EDR) solutions to detect anomalous behaviors indicative of exploitation attempts, such as unexpected crashes or code execution patterns. 6) Conduct user awareness training focused on recognizing suspicious files and social engineering tactics that could lead to opening malicious DGN files. 7) Regularly back up critical design data and verify backup integrity to ensure recovery capability in case of compromise or data loss. These targeted actions go beyond generic advice by focusing on the specific attack vector and operational context of AutoCAD environments.
