CVE-2023-39965Public exploitNetwork attack vector

Authenticated file disclosure via unchecked download path

Published Aug 10, 2023 · Updated Oct 4, 2024

Incorrect authorization in FIT2CLOUD 1Panel 1.4.3 allows remote authenticated users to read arbitrary server files through its API. The DownloadFile handler for POST /api/v1/files/download/bypath binds a caller-controlled path and passes it directly to the file response without an authorization check restricting readable paths. A valid panel session is required; exploitation discloses files readable by the 1Panel service account, including sensitive configuration data.
