CVE-2025-6633 is a high-severity vulnerability identified in Autodesk 3ds Max version 2026, involving an Out-of-Bounds Write (CWE-787) triggered by processing a specially crafted RBG file. This vulnerability arises when the software parses the maliciously crafted file, leading to memory corruption by writing data outside the intended buffer boundaries. Such memory corruption can cause application crashes, data corruption, or, more critically, arbitrary code execution within the context of the 3ds Max process. The vulnerability does not require prior authentication but does require user interaction, specifically opening or importing the malicious RBG file. The CVSS 3.1 base score is 8.3, reflecting a network attack vector with low attack complexity, no privileges required, user interaction needed, unchanged scope, and high impact on confidentiality and integrity, with low impact on availability. Exploitation could allow attackers to execute code remotely, potentially leading to system compromise or lateral movement within a network if 3ds Max is used in a connected environment. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may rely on vendor updates or workarounds. Given the nature of 3ds Max as a widely used 3D modeling and rendering software in industries such as media, entertainment, architecture, and manufacturing, this vulnerability poses a significant risk to organizations relying on this software for critical workflows.

For European organizations, the impact of CVE-2025-6633 can be substantial, especially in sectors heavily dependent on Autodesk 3ds Max, such as media production studios, architectural firms, and manufacturing design companies. Exploitation could lead to unauthorized code execution, resulting in intellectual property theft, disruption of design workflows, or insertion of malicious payloads into design files. Confidentiality breaches could expose proprietary designs or client data, while integrity violations could corrupt critical project files, causing delays and financial losses. Availability impact is lower but still relevant if crashes disrupt ongoing work. Additionally, compromised systems could serve as footholds for broader network intrusions, especially in collaborative environments. The requirement for user interaction (opening a malicious file) suggests that social engineering or phishing campaigns targeting designers and engineers could be vectors for exploitation. The lack of patches at the time of disclosure increases the window of exposure, emphasizing the need for proactive risk management.

To mitigate CVE-2025-6633, European organizations should implement several targeted measures beyond generic advice: 1) Enforce strict file handling policies restricting the opening of RBG files from untrusted or unknown sources, including email attachments and downloads. 2) Educate users, particularly designers and engineers, about the risks of opening unsolicited or suspicious files and the importance of verifying file origins. 3) Employ application whitelisting and sandboxing techniques to isolate 3ds Max processes, limiting the impact of potential exploitation. 4) Monitor network and endpoint activity for anomalous behavior indicative of exploitation attempts, such as unexpected crashes or unusual process activity related to 3ds Max. 5) Coordinate with Autodesk for timely patch deployment once available and consider temporary disabling of RBG file import functionality if feasible. 6) Implement robust backup and version control systems for design files to recover from potential data corruption. 7) Integrate file integrity monitoring to detect unauthorized modifications to critical project files. These measures collectively reduce the attack surface and enhance detection and response capabilities.
