CVE-2021-22651

Code execution via Creo archive path traversal

Published Feb 23, 2021 · Updated Aug 3, 2024

Path traversal in Luxion KeyShot products before 10.1 allows attackers to place arbitrary scripts through a crafted Creo archive. The Creo importer extracts ZIP-based EDZ, PYC, or C3DI entries without validating user-supplied paths, permitting writes outside the temporary destination. A user must open or import the malicious file; a deposited startup script can execute at the next system startup in that user's security context.
