CVE-2023-6116Network attack vector

Unauthenticated code execution via HTTP URL stack overflow

Published Apr 26, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in Hanwha Vision XRN-420S 5.01.52 and earlier allows remote attackers to execute code via HTTP URL parameters. Processing attacker-controlled URL parameters overruns a stack buffer, permitting supplied code to control execution. Exploitation requires the correct stack base address, which varies with firmware and configuration; success grants unauthenticated control of the recorder.
