Description
The vulnerability allows a remote attacker to write files to arbitrary paths.
The vulnerability exists due to improper handling of case sensitivity in pkg/modules/exiftool/exiftool.go when processing metadata write requests through the HTTP API. A remote attacker can send specially crafted metadata with alternate casing for dangerous pseudo-tags to write files to arbitrary paths.
Exploitation was confirmed via the unauthenticated HTTP API, and in containerized deployments the impact is limited to the container filesystem.
