CVE-2022-41306 is a high-severity memory corruption vulnerability identified in Autodesk® Design Review 2018. The vulnerability arises when the application processes a maliciously crafted PCT file, leading to a write access violation that causes memory corruption. This type of vulnerability is categorized under CWE-787 (Out-of-bounds Write), which typically allows an attacker to overwrite memory locations, potentially leading to arbitrary code execution. While the vulnerability itself does not directly enable code execution, it can be exploited in conjunction with other vulnerabilities to execute code within the context of the current process. The attack vector is local (AV:L), meaning the attacker must have local access to the system to exploit the flaw. No privileges are required (PR:N), but user interaction is necessary (UI:R), implying that the victim must open or otherwise interact with the malicious PCT file through DesignReview.exe. The vulnerability impacts confidentiality, integrity, and availability (all rated high), indicating that successful exploitation could lead to full compromise of the affected system. Autodesk has not provided a patch link, suggesting that either a patch is not yet available or it must be obtained through other official channels. No known exploits are currently reported in the wild, but the high CVSS score of 7.8 underscores the critical nature of this vulnerability. Organizations using Autodesk Design Review 2018 should consider this a significant risk, especially in environments where untrusted files might be opened.

For European organizations, the impact of CVE-2022-41306 can be substantial, particularly in industries relying heavily on CAD and design review tools, such as manufacturing, architecture, engineering, and construction. Exploitation could lead to unauthorized code execution, allowing attackers to compromise sensitive design data, intellectual property, or disrupt operational workflows. Given that the vulnerability affects confidentiality, integrity, and availability, attackers could exfiltrate proprietary information, alter design files, or cause denial of service by crashing the application or the host system. This could result in financial losses, reputational damage, and potential regulatory compliance issues under GDPR if personal or sensitive data is involved. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in scenarios where phishing or social engineering could induce users to open malicious files. The absence of known exploits in the wild currently reduces immediate threat levels but does not preclude future exploitation, especially as threat actors often develop exploits for high-impact vulnerabilities over time.

European organizations should implement the following specific mitigations: 1) Restrict access to Autodesk Design Review 2018 to trusted users and environments only, minimizing exposure to untrusted files. 2) Educate users about the risks of opening unsolicited or unverified PCT files, emphasizing cautious handling of email attachments and downloads. 3) Employ application whitelisting and sandboxing techniques to isolate Design Review processes, limiting the impact of potential exploitation. 4) Monitor and control local user privileges to reduce the risk of exploitation by limiting the ability to execute unauthorized code. 5) Regularly check Autodesk’s official channels for patches or updates addressing this vulnerability and apply them promptly once available. 6) Implement network segmentation to contain potential breaches and prevent lateral movement. 7) Use endpoint detection and response (EDR) solutions to detect anomalous behavior related to Design Review processes. 8) Consider upgrading to newer versions of Autodesk Design Review if they are not affected by this vulnerability or provide better security controls.
