CVE-2024-11581
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedLuxion KeyShot JT File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Luxion KeyShot. 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 jt files. The issue results from the lack of proper validation of user-supplied data, which can result in a read before the start of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-23826.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability exists in Luxion KeyShot's JT file parser due to insufficient validation of user-supplied data. The parser reads data before the start of an allocated buffer when processing malicious JT files, which can be leveraged to achieve remote code execution in the context of the current process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify KeyShot installationSearch for KeyShot in installed programs or check common installation directories (Program Files, Program Files x86) for KeyShot executable filesAffected if Luxion KeyShot software is present on the system
-
Determine installed KeyShot versionRight-click the KeyShot executable, select Properties, and check the Details tab for version information, or launch KeyShot and navigate to Help > About to view the version numberAffected if The installed version is lower than 2024.3 (for example, 2024.2, 13.x, 12.x, etc.)
-
Confirm JT file handling is enabledCheck if .jt file extension associations are registered with KeyShot by viewing default file associations in Windows Settings > Apps > Default apps, or check if KeyShot can open JT files directlyAffected if JT files are associated with KeyShot or can be opened by the application
-
Identify recent JT file processing activityReview Windows Event Viewer logs, KeyShot application logs, or file history to identify recently opened JT files, especially from untrusted or external sourcesAffected if Any JT files have been opened in KeyShot, particularly from untrusted sources since the vulnerability requires processing a malicious JT file
A system is affected if Luxion KeyShot version 2024.3 or earlier is installed and the JT file parser feature is active, meaning the vulnerability can be triggered by opening a specially crafted JT file.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2024.3
Users should avoid opening untrusted JT files or visiting malicious pages until an official vendor patch is released. Consider restricting or temporarily disabling JT file associations in KeyShot as a defensive measure.
KeyShot 2024.3
- Navigate to the official KeyShot download page at download.keyshot.com
- Locate and download KeyShot version 2024.3 or later
- Close any running KeyShot instances
- Run the installer and follow the prompts to upgrade
- Restart KeyShot after installation completes
- Verify the installed version by checking Help > About KeyShot
