CVE-2025-41392: CWE-125 Out-of-bounds Read in Ashlar-Vellum Cobalt
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing AR files. This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
AI Analysis
Technical Summary
CVE-2025-41392 is a high-severity vulnerability identified in multiple versions of Ashlar-Vellum's design software products, including Cobalt, Xenon, Argon, Lithium, and Cobalt Share, specifically versions prior to 12.6.1204.204. The vulnerability arises from improper validation of user-supplied data when parsing AR files, which are likely proprietary or specialized archive or resource files used by these applications. This improper validation leads to an out-of-bounds read (CWE-125), a memory safety issue where the software reads data beyond the allocated buffer boundaries. Such out-of-bounds reads can cause undefined behavior, including application crashes, information disclosure, or potentially enable an attacker to execute arbitrary code within the context of the affected process. The CVSS 4.0 score of 8.4 reflects a high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:A). The vulnerability impacts confidentiality, integrity, and availability highly (VC:H, VI:H, VA:H). The lack of authentication requirements combined with the ability to execute arbitrary code makes this a critical concern for users of these products. Although no known exploits are currently reported in the wild, the potential for exploitation exists, especially if attackers can trick users into opening crafted AR files. The vulnerability affects multiple Ashlar-Vellum products, which are specialized CAD and design tools, often used in engineering, architecture, and manufacturing sectors. The absence of published patches at the time of disclosure means users must rely on mitigations until updates are available.
Potential Impact
For European organizations, especially those in engineering, manufacturing, architecture, and design sectors that rely on Ashlar-Vellum products, this vulnerability poses a significant risk. Successful exploitation could lead to arbitrary code execution, potentially allowing attackers to compromise sensitive design data, intellectual property, and disrupt business operations. Given the high impact on confidentiality, integrity, and availability, attackers could exfiltrate proprietary designs, inject malicious code into design files, or cause denial of service by crashing applications. This could have downstream effects on supply chains and project timelines. The requirement for local access and user interaction means phishing or social engineering attacks could be vectors, targeting employees who handle AR files. The lack of authentication requirements increases risk in environments where users have access to untrusted files. European organizations with stringent data protection regulations (e.g., GDPR) must consider the potential data breach implications and compliance risks. Additionally, disruption in critical infrastructure sectors using these tools could have broader economic impacts.
Mitigation Recommendations
1. Immediate mitigation should focus on user awareness and training to avoid opening AR files from untrusted or unknown sources. 2. Implement strict file handling policies and sandboxing for design applications to limit the impact of potential exploitation. 3. Employ endpoint detection and response (EDR) solutions to monitor for abnormal behaviors indicative of exploitation attempts, such as unexpected process executions or memory access violations. 4. Network segmentation to isolate systems running Ashlar-Vellum products can reduce lateral movement if compromise occurs. 5. Regularly back up critical design files and maintain version control to recover from potential data corruption or ransomware attacks. 6. Monitor vendor communications closely for patches or updates addressing this vulnerability and prioritize timely application once available. 7. Consider deploying application whitelisting and restricting execution privileges to minimize the risk of arbitrary code execution. 8. Use file integrity monitoring to detect unauthorized changes to AR files or application binaries. These measures go beyond generic advice by focusing on operational controls tailored to the affected software and its usage context.
