A file-transfer interface that requires valid credentials accepts attacker-controlled filenames without restricting shell metacharacters. An automated process later constructs and runs a system command using the uploaded file's name, allowing an authenticated attacker to embed and execute arbitrary operating system commands with the privileges of that process. This allows an attacker to read and modify ingested log data, and could provide a foothold for further movement within the internal network.
