Arbitrary file write via unsanitized log path
Published Oct 4, 2021 · Updated Aug 4, 2024
Path traversal in Cobbler before 3.3.0 allows remote attackers to write arbitrary files through the upload_log_data XML-RPC method. The method incorporated an unvalidated system name into the destination path, allowing traversal components to escape the anamon log directory before file data was written. Exploitation requires the network-accessible XML-RPC service and the non-default anamon_enabled setting, but no authentication or user interaction is required.
