Release Date
14 July 2026

Summary

SIP is a free Raspberry Pi based Python program for controlling irrigation systems (sprinkler, drip, hydroponic, etc). It uses web technology to provide an intuitive user interface (UI) in several languages. The UI can be accessed in your favorite browser on desktop, laptop, and mobile devices. SIP has also been used to control pumps, lights, and other Irrigation related equipment.

Description

The SIP Backup/Restore functionality suffers from a path traversal vulnerability. The keys in the JSON backup file which have been uploaded are not validated when they are used to generate file paths. An attacker with access to the restore feature can use the path traversal vulnerability to write JSON files outside the intended data directory. When the optional passphrase is not enabled (factory default) these actions are additionally available to any unauthenticated user, and where the passphrase is enabled it defaults to 'opendoor'.
