Technical Analysis

CVE-2025-6634 is a high-severity buffer overflow vulnerability (CWE-120) identified in Autodesk 3ds Max version 2026. The flaw arises from improper handling of TGA image files when they are linked or imported into the software. Specifically, the vulnerability is due to a buffer copy operation that does not properly check the size of the input data, leading to memory corruption. An attacker can craft a malicious TGA file designed to exploit this weakness, causing the application to overwrite memory regions. This can result in arbitrary code execution within the context of the 3ds Max process. The vulnerability requires local access to the system (Attack Vector: Local) and does not require privileges (PR:N), but does require user interaction (UI:R) to open or import the malicious file. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Although no known exploits are currently in the wild, the nature of the vulnerability and the widespread use of 3ds Max in professional environments make it a significant risk. The vulnerability could be leveraged to execute malicious payloads, potentially leading to system compromise, data theft, or disruption of design workflows.

Potential Impact

For European organizations, especially those in industries relying heavily on 3D modeling and design such as architecture, engineering, media, and entertainment, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized code execution, enabling attackers to steal intellectual property, disrupt production pipelines, or establish footholds for further network intrusion. Given that 3ds Max is often used in collaborative environments, a compromised system could serve as a pivot point to access sensitive project data or internal networks. The requirement for user interaction means phishing or social engineering could be used to deliver the malicious TGA file, increasing the risk in environments where file sharing is common. Additionally, the high impact on confidentiality, integrity, and availability could result in significant operational and financial damage, including reputational harm and regulatory consequences under GDPR if personal or sensitive data is exposed.

Mitigation Recommendations

Organizations should implement a multi-layered approach to mitigate this vulnerability. First, restrict the use of Autodesk 3ds Max 2026 to trusted users and environments until a vendor patch is released. Employ strict file validation and scanning mechanisms on all incoming TGA files, including those received via email or file sharing platforms, to detect and block malicious content. Educate users about the risks of opening untrusted files and enforce policies limiting the import of files from unknown sources. Utilize application whitelisting and sandboxing techniques to contain the impact of potential exploitation. Monitor systems for unusual behavior indicative of exploitation attempts, such as unexpected process activity or memory anomalies. Finally, maintain an active vulnerability management program to promptly apply patches once Autodesk releases a fix. If possible, consider temporarily downgrading to a previous 3ds Max version not affected by this vulnerability or using alternative software until remediation is available.
