CVE-2024-23788

Unauthenticated SSRF via arbitrary outbound GET requests

Published Feb 14, 2024 · Updated Mar 19, 2025

SSRF in Sharp Cloud-based Energy Controller JH-RVB1 and JH-RV11 B0.1.9.1 and earlier allows remote attackers to issue arbitrary HTTP GET requests. Sharp has not published the affected request handler or how attacker-controlled input becomes the destination of the outbound GET request. Exploitation requires unauthenticated access from the same network and can make the controller originate requests against other systems.
