CVE-2024-22187Network attack vector

Unauthenticated code execution via arbitrary memory write

Published May 28, 2024 · Updated Feb 13, 2025

Improper access control in AutomationDirect P3-550E 1.2.10.9 allows remote attackers to execute code via a crafted UDP packet. The UDP 9999 Programming Software Connection handler for IMM 0x01A2 accepts a destination address and data from the packet, then writes that data directly to the supplied memory address. No authentication or user interaction is required; properly formatted request sequences can modify arbitrary device memory and achieve remote code execution.
