CVE-2024-29947Network attack vector

Authenticated process crash via malformed message parameter

Published Apr 2, 2024 · Updated Oct 31, 2024

NULL pointer dereference in Hikvision DS-7604NI-K1/4P(B) V4.30.096 build221220 and earlier allows remote authenticated users to crash a process. The message-processing code insufficiently validates an unspecified parameter and dereferences a resulting NULL pointer. Administrative access and network reachability are required; the reported consequence is a service interruption without data exposure or modification.
