CVE-2023-40062

SYSTEM command execution via incomplete input denylist

Published Nov 1, 2023 · Updated Sep 5, 2024

Improper input validation in SolarWinds Platform 2023.3.1 and earlier allows remote authenticated users to execute commands as SYSTEM. SolarWinds identifies an incomplete disallowed-input list but has not published the affected endpoint, function, or exact validation omission. A low-privileged account on an adjacent network is sufficient; successful exploitation grants full SYSTEM-level control of the Windows server.
