CVE-2022-47525Network attack vector

Downstream crash via crafted UDP packet

Published May 30, 2023 · Updated Jan 14, 2025

Divide by zero in Fox-IT DataDiode Core 3.4.3 and earlier allows remote attackers to crash the downstream node via a crafted UDP packet. The packet parser performs a division with a zero divisor while processing attacker-controlled UDP packet data instead of rejecting the malformed packet. No authentication or user interaction is required; exploitation interrupts the downstream service without compromising confidentiality or integrity.
