CVE-2024-13047 is a vulnerability identified in Ashlar-Vellum Cobalt version 1204.90, a CAD software product used for design and modeling. The flaw is a type confusion vulnerability (CWE-843) that occurs during the parsing of CO files, which are native to the software. Type confusion arises when the program incorrectly interprets data types, leading to memory corruption or unexpected behavior. In this case, the software fails to properly validate user-supplied data within CO files, allowing an attacker to craft a malicious file that triggers this condition. When a user opens such a file or visits a malicious page that causes the file to be processed, the attacker can execute arbitrary code within the context of the current process. This can lead to full system compromise depending on the privileges of the running application. The vulnerability requires user interaction, which limits remote exploitation but does not eliminate risk, especially in environments where users frequently exchange design files. The CVSS 3.0 score of 7.8 indicates a high severity with attack vector local (requiring user action), low attack complexity, no privileges required, user interaction needed, and high impact on confidentiality, integrity, and availability. No patches or exploits are currently publicly available, but the vulnerability was reported by the Zero Day Initiative (ZDI) as ZDI-CAN-24843 and is now published. Organizations relying on Ashlar-Vellum Cobalt should be aware of this threat and prepare to deploy fixes once released.

The potential impact of CVE-2024-13047 is significant for organizations using Ashlar-Vellum Cobalt, particularly in industries such as manufacturing, engineering, and design where this software is integral. Successful exploitation allows attackers to execute arbitrary code, potentially leading to full system compromise, data theft, sabotage of design files, or deployment of further malware. Confidentiality is at risk as attackers could access sensitive intellectual property and design data. Integrity is compromised since attackers can alter or corrupt design files, impacting product quality and safety. Availability may be affected if the attacker disrupts the software or system operations. The requirement for user interaction reduces the risk of widespread automated exploitation but does not prevent targeted attacks, especially via phishing or malicious file sharing. The lack of known exploits in the wild currently limits immediate threat but organizations should not be complacent. The vulnerability could be leveraged in supply chain attacks or espionage campaigns targeting critical infrastructure or high-value industrial targets.

1. Immediately restrict the opening of CO files to trusted sources only and implement strict file validation policies. 2. Educate users about the risks of opening files from untrusted or unknown origins, emphasizing phishing and social engineering awareness. 3. Monitor network and endpoint activity for unusual behavior related to Ashlar-Vellum Cobalt, such as unexpected file parsing or process execution. 4. Employ application whitelisting and sandboxing techniques to limit the impact of potential code execution within the software. 5. Maintain up-to-date backups of critical design files to enable recovery in case of compromise. 6. Coordinate with Ashlar-Vellum for timely patch deployment once a fix is released; track vendor advisories closely. 7. Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation attempts involving type confusion or memory corruption. 8. Limit user privileges on systems running Cobalt to reduce the potential impact of code execution. 9. If possible, isolate CAD workstations from general internet access to reduce exposure to malicious web content. 10. Review and update incident response plans to include scenarios involving exploitation of this vulnerability.
