Arbitrary controller file write via unchecked TargetPath
Published Mar 10, 2020 · Updated Aug 4, 2024
Path traversal in WAGO e!COCKPIT 1.6.0.7 allows attackers to write arbitrary files to connected controllers through a crafted WUP file. FirmwareUpdate.DownloadFirmware trusts each AssociatedFiles File element's TargetPath and passes it to SFTP UploadFile without constraining the destination. An authorized user must select the package and enter controller administrator or root credentials; injected files inherit that access and can execute with elevated privileges.
