CVE-2024-5506 in KeyShot Viewer
Summary
by MITRE • 06/06/2024
Luxion KeyShot Viewer KSP File Parsing Out-Of-Bounds Write 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 parsing of KSP files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22514.

The CVE-2024-5506 vulnerability represents a critical out-of-bounds write flaw in Luxion KeyShot Viewer's handling of KSP files, demonstrating a classic buffer overflow condition that enables remote code execution. This vulnerability resides within the file parsing subsystem where the application fails to properly validate user-supplied data during KSP file processing, creating a scenario where malicious input can cause the program to write data beyond the bounds of allocated memory buffers. The flaw specifically manifests when the viewer parses KSP files that contain crafted malicious data structures, allowing an attacker to manipulate memory layout and potentially overwrite critical program data or execution pointers. The vulnerability's classification as a remote code execution issue stems from its ability to be triggered without local access, requiring only that a user interact with a malicious file or webpage containing the crafted KSP content. This makes it particularly dangerous in environments where users might encounter such files through email attachments, web downloads, or compromised websites.
The technical implementation of this vulnerability follows established patterns found in buffer overflow exploits, where improper input validation creates opportunities for attackers to manipulate program execution flow. The lack of bounds checking during KSP file parsing means that when the application attempts to write data to memory locations beyond the intended buffer boundaries, it can overwrite adjacent memory regions including function return addresses, stack canaries, or other critical program variables. This type of vulnerability directly maps to CWE-121, which describes stack-based buffer overflow conditions, and CWE-787, which covers out-of-bounds write vulnerabilities. The attack surface is further expanded by the fact that KeyShot Viewer is commonly used for 3D visualization and product design, making it a legitimate application that users are likely to encounter in professional environments, increasing the likelihood of successful exploitation through social engineering attacks that trick users into opening malicious files. The vulnerability's exploitation requires user interaction, typically through opening a malicious KSP file, which aligns with attack patterns documented in the MITRE ATT&CK framework under technique T1203 for Exploitation for Client Execution, where adversaries leverage legitimate software to execute malicious code.
The operational impact of CVE-2024-5506 extends beyond simple code execution, as successful exploitation could enable attackers to gain full control over affected systems, potentially leading to data exfiltration, persistent backdoor installation, or further network reconnaissance. Organizations using KeyShot Viewer in design, engineering, or product development environments face heightened risk since these applications are often trusted and frequently opened by multiple users, creating a wide attack surface. The vulnerability's remote execution capability means that attackers could deploy this exploit through various vectors including phishing campaigns targeting design professionals, compromised websites hosting malicious KSP files, or even through supply chain attacks if the application is distributed through third-party channels. Security professionals must consider that this vulnerability could be leveraged for advanced persistent threat campaigns where attackers establish footholds in engineering environments to access sensitive product designs, intellectual property, or proprietary 3D models. The impact is particularly severe in industries such as automotive, aerospace, and consumer electronics where KeyShot Viewer is extensively used for product visualization and development, as compromise of these systems could result in significant financial loss and competitive disadvantage. Organizations should prioritize patch management and user education to mitigate this risk, as the vulnerability's exploitation requires minimal technical skill from attackers and can be effectively weaponized through standard social engineering techniques.
