CVE-2025-0412 in KeyShot Viewer
Summary
by MITRE • 01/13/2025
Luxion KeyShot Viewer KSP File Parsing Memory Corruption Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Luxion KeyShot Viewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of KSP files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22139.

The CVE-2025-0412 vulnerability represents a critical memory corruption flaw in Luxion KeyShot Viewer's handling of KSP files, exposing users to significant remote code execution risks. This vulnerability falls under the category of input validation failures that can lead to arbitrary code execution, making it particularly dangerous for organizations relying on 3D modeling and visualization software. The flaw specifically manifests during the parsing of KSP files, which are used by KeyShot Viewer for storing 3D scene configurations and rendering settings. Attackers can exploit this weakness by crafting malicious KSP files or hosting them on compromised websites that users might inadvertently access, requiring only user interaction to trigger the exploit through normal software usage patterns.
The technical root cause of this vulnerability stems from insufficient validation of user-supplied data during KSP file processing within the KeyShot Viewer application. When the software attempts to parse maliciously crafted KSP files, it fails to properly sanitize or validate the input data structure, leading to memory corruption conditions that can be leveraged for code execution. This memory corruption typically occurs through buffer overflows or improper memory allocation handling, where attacker-controlled data exceeds expected boundaries and overwrites adjacent memory locations. The vulnerability's classification aligns with CWE-121, which addresses stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios. The exploitation mechanism operates by manipulating the KSP file format's internal structure to trigger memory corruption during parsing operations, potentially allowing attackers to execute arbitrary code with the privileges of the running KeyShot Viewer process.
The operational impact of CVE-2025-0412 extends beyond simple remote code execution, as it can enable attackers to establish persistent access to compromised systems through various attack vectors. Once successfully exploited, the vulnerability allows adversaries to execute malicious code in the context of the current process, potentially leading to complete system compromise. This represents a significant concern for organizations using KeyShot Viewer for design reviews, product visualization, or collaborative 3D modeling workflows where users might encounter malicious files through email attachments, web downloads, or shared network resources. The vulnerability's remote exploitation capability means that attackers don't require physical access to target systems, making it particularly dangerous in enterprise environments where users frequently interact with external content. The ZDI-CAN-22139 reference indicates this vulnerability was previously identified and tracked by the Zero Day Initiative, highlighting its recognition as a significant security risk in the cybersecurity community.
Mitigation strategies for CVE-2025-0412 should focus on both immediate protective measures and long-term security improvements. Organizations should prioritize applying vendor-provided patches and updates as soon as they become available, since this vulnerability enables direct code execution without requiring additional privileges or complex attack chains. Network-based protections such as web application firewalls and content filtering systems can help prevent users from accessing malicious KSP files through web-based delivery mechanisms. Security awareness training should emphasize the dangers of opening unknown or untrusted KSP files, particularly those received via email or downloaded from unverified sources. Additional protective measures include implementing least privilege access controls for KeyShot Viewer installations, restricting file type associations, and monitoring for suspicious file access patterns. The vulnerability's characteristics align with ATT&CK technique T1203, which covers exploitation for execution through web-based attacks, and T1059, which covers command and scripting interpreter usage for code execution. Regular security assessments and penetration testing should include evaluation of third-party software components to identify similar input validation vulnerabilities in other applications within the organization's attack surface.
