CVE-2023-39226Network attack vector

Unauthenticated code execution via exposed RunScript method

Published Nov 30, 2023 · Updated Aug 2, 2024

Remote code execution in Delta Electronics InfraSuite Device Master 1.0.7 and earlier allows remote attackers to run code via one UDP packet. The UDP-accessible RunScript method exposes a dangerous function without authentication and executes attacker-supplied script content as the service's current user. No credentials or user interaction are required, and successful exploitation grants code execution with that service account's privileges.
