Sustainable Irrigation Platform (SIP) through version 5.2.16 contains a path traversal vulnerability that allows attackers with access to the restore functionality to write files to arbitrary locations by uploading crafted JSON backup files with unvalidated keys used to construct file paths. Attackers can exploit the lack of key validation in the JSON restore process, combined with the absence of a required passphrase in the default configuration or the default passphrase 'opendoor', to write arbitrary JSON files outside the intended data directory.
