CVE-2023-45188Network attack vector

Authenticated code execution via extension-only upload validation

Published Jun 9, 2024 · Updated Aug 2, 2024

Unrestricted file upload in IBM Engineering Lifecycle Optimization - Publishing 7.0.2 and 7.0.3 allows remote authenticated users to execute code. The file-upload path validates extensions improperly and accepts a crafted malicious file, allowing it to reach an executable context. Low-privileged authenticated access is required; IBM does not disclose the request endpoint or server-side validation routine.
