CVE-2024-4197Network attack vector

Authenticated code execution via unrestricted file upload

Published Jun 25, 2024 · Updated Aug 1, 2024

Unrestricted file upload in Avaya IP Office before 11.1.3.1 allows remote authenticated users to execute code through One-X. The One-X component accepts a user-supplied file without restricting dangerous file types, allowing uploaded content to execute as commands or code. A low-privileged authenticated session and network access to One-X are required; successful exploitation compromises the server.
