CVE-2024-34909Network attack vector

Code execution via crafted PDF upload

Published May 15, 2024 · Updated Feb 13, 2025

Unrestricted file upload in KY KMS 1.0.1 and earlier allows remote attackers to execute arbitrary code through a crafted PDF file. The public record does not identify the upload endpoint, file-validation logic, storage path, or code path that processes the uploaded PDF. The publication does not state whether authentication or user interaction is required, leaving exposure of the upload interface as the unresolved gate.
