Sustainable Irrigation Platform 5.2.16 SSRF via Node-RED Callback URL

Sustainable Irrigation Platform (SIP) through version 5.2.16 contains a server-side request forgery (SSRF) vulnerability that allows unauthenticated attackers to make the device issue arbitrary HTTP requests by supplying a malicious callback URL when the optional Node-RED plugin is installed. Attackers can exploit the lack of destination validation and the default passphrase 'opendoor' to send blind HTTP requests to arbitrary internal or external hosts not otherwise directly accessible.
