CVE-2025-1660 is a high-severity memory corruption vulnerability classified under CWE-120 (Classic Buffer Overflow) affecting Autodesk Navisworks Freedom 2025. The vulnerability arises from improper handling of input size during the parsing of DWFX files, which are design data exchange files commonly used in architecture, engineering, and construction workflows. Specifically, a maliciously crafted DWFX file can trigger a buffer overflow condition by copying data without adequate size checks, leading to memory corruption. This corruption can be exploited by an attacker to execute arbitrary code within the context of the Navisworks Freedom process. The vulnerability requires local access (Attack Vector: Local) but does not require privileges (Privileges Required: None), though it does require user interaction (UI Required: Yes) such as opening or importing the malicious DWFX file. The impact on confidentiality, integrity, and availability is high, as arbitrary code execution could allow an attacker to take full control of the affected application and potentially the underlying system depending on user permissions. No known exploits are currently reported in the wild, and no patches have been published at the time of disclosure. Autodesk Navisworks Freedom is widely used in project review and coordination within the AEC (Architecture, Engineering, and Construction) sector, making this vulnerability particularly relevant to organizations handling complex design data and collaborative workflows.

For European organizations, especially those in the AEC industry, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to steal sensitive design data, disrupt project workflows, or deploy malware within corporate networks. Given the collaborative nature of these projects, compromised systems could serve as pivot points for lateral movement, threatening broader enterprise security. The high confidentiality impact is critical as design files often contain proprietary or regulated information. Integrity and availability impacts are also severe, as corrupted or manipulated project files could cause project delays or financial losses. The requirement for user interaction means social engineering or phishing tactics could be used to trick users into opening malicious DWFX files, increasing the attack surface. European organizations with extensive use of Autodesk Navisworks Freedom in construction, engineering, or infrastructure projects are particularly vulnerable. Additionally, the lack of available patches at disclosure heightens the urgency for interim mitigations.

1. Implement strict file handling policies: Restrict the acceptance and opening of DWFX files from untrusted or unknown sources. 2. Employ sandboxing: Run Autodesk Navisworks Freedom within isolated environments or virtual machines to limit the impact of potential exploitation. 3. User training: Educate users on the risks of opening unsolicited or suspicious DWFX files and encourage verification of file sources. 4. Monitor application behavior: Use endpoint detection and response (EDR) tools to detect anomalous behavior indicative of exploitation attempts. 5. Network segmentation: Isolate systems running Navisworks Freedom from critical infrastructure to reduce lateral movement risk. 6. Maintain up-to-date backups of project files to enable recovery in case of data corruption or ransomware attacks. 7. Coordinate with Autodesk for timely patch deployment once available, and subscribe to vendor advisories for updates. 8. Consider disabling or limiting DWFX file import functionality if feasible until patches are released.
