CVE-2023-3121Public exploit

Authenticated SSRF via unrestricted image URL fetch

Published Jun 6, 2023 · Updated Aug 2, 2024

SSRF in Dahua Smart Parking Management 20230528 and earlier allows remote authenticated users to make server-side requests via fileUrl. The /ipms/imageConvert/image endpoint fetches a user-controlled URL without restricting the request destination. Exploitation requires low-privileged access from an adjacent network and makes the server contact attacker-chosen destinations.
