CVE-2025-6633 is a high-severity vulnerability identified in Autodesk 3ds Max version 2026. The flaw is classified as a CWE-787 Out-of-Bounds Write, which occurs when the software improperly handles a maliciously crafted RBG file during parsing. This vulnerability allows an attacker to write data outside the intended memory boundaries, potentially leading to memory corruption. Exploitation can result in a crash of the application, data corruption, or, more critically, arbitrary code execution within the context of the current process. The vulnerability requires local access (attack vector: local), does not require privileges (PR:N), but does require user interaction (UI:R), such as opening or importing a malicious RBG file. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component. The CVSS v3.1 base score is 7.8, reflecting high severity with high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, and no patches have been linked yet. Autodesk 3ds Max is a widely used 3D modeling, animation, and rendering software, especially in industries such as media, entertainment, architecture, and design. The vulnerability's exploitation could allow attackers to execute arbitrary code, potentially leading to system compromise or further lateral movement within a network if the affected system is connected to sensitive environments.

For European organizations, the impact of CVE-2025-6633 can be significant, particularly for companies in creative industries, architectural firms, engineering consultancies, and media production houses that rely on Autodesk 3ds Max for their workflows. Successful exploitation could lead to intellectual property theft, disruption of critical design projects, or insertion of malicious code that compromises the integrity of design files and systems. Given the high confidentiality and integrity impact, sensitive design data could be exposed or altered, affecting business operations and client trust. Moreover, if exploited within a corporate network, this vulnerability could serve as an entry point for attackers to escalate privileges or move laterally, potentially impacting broader IT infrastructure. The requirement for user interaction limits remote exploitation but does not eliminate risk, as targeted phishing or social engineering could trick users into opening malicious files. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation attempts.

European organizations should implement a multi-layered mitigation approach: 1) Restrict the use of Autodesk 3ds Max to trusted users and environments, limiting exposure to untrusted RBG files. 2) Educate users on the risks of opening files from unknown or unverified sources, emphasizing caution with RBG files. 3) Monitor and control file exchange channels to detect and block potentially malicious RBG files before they reach end users. 4) Employ application whitelisting and sandboxing techniques to contain the impact of any exploitation attempts. 5) Maintain up-to-date backups of critical design files to recover from potential data corruption. 6) Monitor vendor communications closely for patches or updates addressing this vulnerability and apply them promptly once available. 7) Consider network segmentation to isolate systems running Autodesk 3ds Max from sensitive or critical infrastructure to limit lateral movement in case of compromise. 8) Use endpoint detection and response (EDR) solutions to detect anomalous behaviors indicative of exploitation attempts.
