Sustainable Irrigation Platform (SIP) through version 5.2.16 contains a command injection vulnerability in the optional cli_control plugin that allows unauthenticated or cross-site request forgery attackers to execute arbitrary operating-system commands by storing a malicious payload via the plugin's HTTP endpoint. Attackers can trigger execution by activating the associated irrigation station, exploiting the absence of passphrase protection or the default passphrase 'opendoor', to achieve arbitrary command execution on the underlying host.
