CVE-2025-6631 is a vulnerability classified under CWE-787 (Out-of-Bounds Write) affecting Autodesk Shared Components version 2026.2. The flaw is triggered when the software parses a maliciously crafted PRT file, a file format commonly used in CAD and design workflows. The out-of-bounds write can corrupt memory beyond the intended buffer, potentially leading to application crashes, data corruption, or arbitrary code execution within the context of the current process. The vulnerability has a CVSS 3.1 base score of 7.8, indicating high severity, with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). This means an attacker must convince a user to open or process a malicious PRT file locally. The vulnerability affects Autodesk Shared Components, which are integral to multiple Autodesk products, implying a broad potential impact across various design and engineering software suites. No patches or known exploits are currently available, but the risk remains significant due to the potential for remote code execution and data integrity compromise. The vulnerability's exploitation could allow attackers to execute arbitrary code, leading to full system compromise or disruption of critical design workflows.

The impact of CVE-2025-6631 is substantial for organizations relying on Autodesk products for design, engineering, and manufacturing processes. Successful exploitation can lead to arbitrary code execution, enabling attackers to gain control over affected systems, steal sensitive intellectual property, or disrupt operations through crashes and data corruption. This poses risks to confidentiality, integrity, and availability of critical design data and systems. Industries such as aerospace, automotive, construction, and manufacturing, which heavily depend on Autodesk software, could face operational downtime, financial losses, and reputational damage. The requirement for local access and user interaction somewhat limits remote exploitation, but targeted attacks via phishing or malicious file distribution remain plausible. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency for organizations to prepare defenses.

To mitigate CVE-2025-6631, organizations should: 1) Monitor Autodesk's official channels for patches or updates addressing this vulnerability and apply them promptly once released. 2) Restrict access to PRT files from untrusted or external sources, implementing strict file handling policies. 3) Employ application whitelisting to prevent unauthorized execution of potentially malicious files. 4) Use sandboxing or isolated environments for opening or processing PRT files, minimizing the risk of system-wide compromise. 5) Educate users about the risks of opening unsolicited or suspicious PRT files, emphasizing cautious handling of design files received via email or external media. 6) Implement endpoint detection and response (EDR) solutions capable of identifying anomalous behavior related to memory corruption or code execution attempts. 7) Regularly back up critical design data to enable recovery in case of data corruption or ransomware attacks leveraging this vulnerability.
