CVE-2024-23478

Authenticated code execution via unsafe JSON deserialization

Published Feb 15, 2024 · Updated Aug 12, 2024

Deserialization in SolarWinds Access Rights Manager 2023.2.2 and earlier allows remote authenticated users to execute code on the ARM server. The JsonSerializationBinder class accepts user-supplied type data without proper validation and deserializes it in the ARM service account context. Exploitation requires authentication and adjacent-network access, and successful execution grants the service account's privileges.
