CVE-2025-1650 is a vulnerability identified in Autodesk AutoCAD versions 2022 through 2025, stemming from the use of an uninitialized variable (CWE-457) during the parsing of CATPRODUCT files. CATPRODUCT files are typically used to represent complex product assemblies, and a maliciously crafted file can trigger this flaw. The uninitialized variable can lead to undefined behavior, which an attacker can exploit to cause a denial of service (application crash), unauthorized disclosure of sensitive information from memory, or execute arbitrary code with the privileges of the AutoCAD process. The vulnerability requires the victim to open a specially crafted CATPRODUCT file, implying user interaction is necessary, and the attack vector is local (AV:L). No privileges are required to exploit it (PR:N), but user interaction is mandatory (UI:R). The vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are currently known, the vulnerability's characteristics suggest that weaponization is feasible. The lack of available patches at the time of disclosure means organizations must rely on interim mitigations. The vulnerability was reserved in late February 2025 and publicly disclosed in March 2025, with enrichment from CISA indicating its recognized importance.

The vulnerability poses a significant risk to organizations using Autodesk AutoCAD, particularly those in sectors such as engineering, architecture, manufacturing, and construction, where CAD files are frequently exchanged. Exploitation can lead to application crashes, disrupting workflows and causing potential data loss. More critically, arbitrary code execution could allow attackers to execute malicious payloads within the context of AutoCAD, potentially leading to system compromise, lateral movement, or data exfiltration. The ability to read sensitive data from memory could expose intellectual property or confidential design information. Given AutoCAD's widespread use in critical infrastructure design and manufacturing, exploitation could have cascading effects on operational continuity and intellectual property security. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where files are shared frequently via email or network shares. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future attacks.

1. Apply official patches from Autodesk immediately once they become available to address CVE-2025-1650. 2. Until patches are released, restrict the opening of CATPRODUCT files from untrusted or unknown sources. 3. Implement strict file validation and scanning policies at email gateways and network file shares to detect and block malicious CATPRODUCT files. 4. Employ application whitelisting and sandboxing techniques to limit AutoCAD's ability to execute arbitrary code or access sensitive system resources. 5. Educate users about the risks of opening unsolicited or unexpected CAD files, emphasizing caution with CATPRODUCT files. 6. Monitor AutoCAD processes and system logs for unusual behavior indicative of exploitation attempts, such as crashes or unexpected memory access patterns. 7. Consider network segmentation to isolate systems running AutoCAD from less trusted network zones to reduce lateral movement risk. 8. Maintain regular backups of critical CAD files and system states to enable recovery in case of successful exploitation.
