Path Traversal in ConvertXis a self-hosted online file converter. In (CVE-2025-66449)
Summary
Path traversal in ConvertXis a self-hosted online file converter. In (CVE-2025-66449). Successful exploitation can lead to full system takeover. Exploitable via file.name.
Original description
The description as published by the source.
ConvertXis a self-hosted online file converter. In versions prior to 0.16.0, the endpoint /upload allows an authenticated user to write arbitrary files on the system, overwriting binaries and allowing code execution. The upload function takes file.name directly from user supplied data without doing any sanitization on the name thus allowing for arbitrary file write. This can be used to overwrite system binaries with ones provided from an attacker allowing full code execution. Version 0.16.0 contains a patch for the issue.
