CVE-2022-41309 is a high-severity memory corruption vulnerability identified in Autodesk Design Review, specifically affecting versions 2011, 2012, 2013, 2017, and 2018. The vulnerability arises when the application processes specially crafted .dwf or .pct files. These files, when opened or consumed by DesignReview.exe, can trigger a write access violation that leads to memory corruption. This vulnerability is classified under CWE-787, which relates to out-of-bounds write errors. While the immediate effect is memory corruption, the vulnerability's exploitation potential increases when chained with other vulnerabilities, potentially enabling an attacker to execute arbitrary code within the context of the current process. The CVSS v3.1 base score is 7.8, indicating a high severity level, with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This means the attack requires local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The scope remains unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No known exploits are reported in the wild, and no official patches have been linked yet. The vulnerability was reserved in September 2022 and published in October 2022. Autodesk Design Review is a widely used tool for viewing and annotating design files, especially in engineering and architectural sectors, making this vulnerability relevant for organizations relying on these workflows.

For European organizations, the impact of CVE-2022-41309 can be significant, particularly for those in engineering, architecture, manufacturing, and construction sectors where Autodesk Design Review is commonly used. Exploitation could lead to unauthorized code execution, potentially allowing attackers to escalate privileges, move laterally within networks, or exfiltrate sensitive design and intellectual property data. Given the high confidentiality, integrity, and availability impacts, successful exploitation could disrupt business operations, compromise proprietary designs, and lead to 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 environments where users might be tricked into opening malicious files via phishing or social engineering. Additionally, the lack of patches increases exposure time, emphasizing the need for proactive mitigation. The potential for chaining with other vulnerabilities further elevates the threat level, as attackers could leverage this as part of a multi-stage attack to gain deeper system control.

Given the absence of official patches, European organizations should implement several targeted mitigations: 1) Restrict usage of Autodesk Design Review to trusted users and environments, minimizing exposure to untrusted .dwf or .pct files. 2) Implement strict file validation and scanning policies at email gateways and endpoint security solutions to detect and block maliciously crafted files before they reach end users. 3) Employ application whitelisting and sandboxing techniques to limit the ability of DesignReview.exe to execute arbitrary code or access sensitive system resources. 4) Educate users on the risks of opening unsolicited or unexpected design files, emphasizing caution with email attachments and downloads. 5) Monitor system and application logs for unusual behavior related to DesignReview.exe, such as crashes or unexpected memory access violations, to detect potential exploitation attempts early. 6) Where possible, isolate systems running vulnerable versions of Autodesk Design Review from critical network segments to contain potential breaches. 7) Regularly review and update endpoint detection and response (EDR) rules to include signatures or heuristics related to this vulnerability. 8) Engage with Autodesk support channels to obtain updates on patches or workarounds and plan for timely application once available.
