CVE-2024-5509
Luxion Keyshot ≤ 2024.1
Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-5509 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Luxion Keyshot. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and AC-3 (Access Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-5509 is an uncontrolled search path element vulnerability in Luxion KeyShot that affects the parsing of BIP files. The flaw permits loading a library from an unsecured location, which can be abused to achieve remote code execution on affected installations. It was originally reported as ZDI-CAN-22738 and carries a CVSS 3.1 score of 7.8.
An unauthenticated attacker can exploit the issue by supplying a malicious BIP file or directing a victim to a malicious page; successful exploitation requires the target user to open the file or visit the page, after which arbitrary code runs in the context of the KeyShot process. The attack vector is local with no privileges required, yet the impact spans confidentiality, integrity, and availability.
Vendor advisories published by Luxion KeyShot CSIRT and the Zero Day Initiative (ZDI-24-540) address the issue and are the authoritative sources for patch and mitigation guidance. The EPSS score has remained flat at 0.0501 with no material increase since disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Establishes restrictive configuration settings that can define and lock down approved search paths.
Enforces approved authorizations so that only intended actors can place or modify elements in the search path.
Limits privileges so unintended actors cannot write to or control directories in the product's search path.
Restricts logical and physical access to change system configuration, including search-path settings and directories.

Secure-development practices directly address design of search paths and resource loading.
Hardened configuration baselines can enforce safe search-path settings and reduce exposure.
Execution allow-listing can block malicious binaries placed in hijackable search locations.

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.
Secure coding practices directly address the use of fixed or controlled search paths that can be influenced by unintended actors.
Configuration management can enforce approved search-path settings but does not inherently prevent the weakness.
