1. EXECUTIVE SUMMARY
- CVSS v3 7.8
- ATTENTION: Low skill level to exploit
- Vendor: Luxion
- Equipment: KeyShot products
- Vulnerabilities: Out-of-bounds Write, Out-of-bounds Read, Insufficient UI Warning of Dangerous Operations, Untrusted Pointer Dereference, Path Traversal
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow arbitrary code execution, the storing of arbitrary scripts into automatic startup folders, and the attacking of products without sufficient UI warning.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of Luxion software, 3D rendering and animation software, are affected:
- KeyShot versions prior to 10.1
- KeyShot Viewer versions prior to 10.1
- KeyShot Network Rendering versions prior to 10.1
- KeyVR versions prior to 10.1
3.2 VULNERABILITY OVERVIEW
The affected product is vulnerable to multiple out-of-bounds write issues while processing project files, which may allow an attacker to execute arbitrary code.
The affected product is vulnerable to an out-of-bounds read while processing project files, which may allow an attacker to execute arbitrary code.
The affected product is vulnerable to an attack because the .bip documents display a “load” command, which can be pointed to a .dll from a remote network share. As a result, the .dll entry point can be executed without sufficient UI warning.
The affected product has multiple NULL pointer dereference issues while processing project files, which may allow an attacker to execute arbitrary code.
When loading a specially crafted file, the application, while processing the extraction of temporary files, suffers from a directory traversal vulnerability, which allows an attacker to store arbitrary scripts into automatic startup folders.

rgod, working with Trend Micro’s Zero Day Initiative, reported these vulnerabilities to CISA.
Luxion has released an update to KeyShot (v10.1) and recommends users update to the latest version.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
- Do not click web links or open unsolicited attachments in email messages.
- Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
- Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
