CVE-2025-21139 is a high-severity vulnerability affecting Adobe Substance3D Designer versions 14.0 and earlier. This vulnerability allows a heap-based buffer overflow, which could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction; specifically, a victim must open a malicious file to trigger the vulnerability.
The Common Vulnerability Scoring System (CVSS) has assigned this vulnerability a score of 7.8, categorizing it as high severity. This rating indicates a significant risk to organizations using affected versions of the product. The attack vector is local, and the complexity of the attack is low, meaning that an attacker could potentially exploit this vulnerability with relative ease, provided the targeted user opens the malicious file.
Risk to organizations includes unauthorized access and potential system compromise, emphasizing the urgency for defenders to patch this vulnerability immediately. The vulnerability was published on January 14, 2025, and organizations should prioritize assessing their exposure to it.
As of the latest updates, there are no known exploits or public proof-of-concept (PoC) available for this vulnerability, but the potential for exploitation remains a concern. Organizations are strongly advised to monitor for updates from Adobe and apply patches as soon as they are available.
Vulnerability Details
The official description of CVE-2025-21139 states that it affects Adobe Substance3D Designer versions 14.0 and earlier due to a heap-based buffer overflow vulnerability. This vulnerability can lead to arbitrary code execution in the context of the current user, necessitating user interaction to exploit. The CVSS score is recorded at 7.8, indicating a high severity risk.
The affected product is Adobe Substance3D Designer, and this vulnerability is classified under CWE-122 and CWE-787. The publication date of this vulnerability is January 14, 2025.
Technical Analysis
The root cause of CVE-2025-21139 is a heap-based buffer overflow, which occurs when data exceeds the allocated memory buffer's limits, leading to potential exploitation. The attack vector for this vulnerability is local, meaning an attacker must have physical or direct access to the machine where the vulnerable software is running.
The complexity of an attack leveraging this vulnerability is low. No special privileges are required for exploitation, but user interaction is necessary, as the victim must open a malicious file. The impacts on confidentiality, integrity, and availability are all classified as high, indicating that successful exploitation could severely compromise the system.
Risk & Impact Analysis
The risk to organizations includes unauthorized access and the potential for arbitrary code execution, which can lead to a full system compromise. This vulnerability is particularly concerning due to its high impact on confidentiality, integrity, and availability. Attackers may leverage this vulnerability to execute malicious code that compromises sensitive data or disrupts services.
Organizations should prioritize patching immediately. Given the local attack vector and the requirement for user interaction, it is crucial that users are educated about the risks of opening untrusted files. Organizations must also implement monitoring for unusual activities that may indicate exploitation attempts.
