CVE-2023-40057Network attack vector

SYSTEM code execution via untrusted deserialization

Published Feb 15, 2024 · Updated Aug 12, 2024

Deserialization of untrusted data in SolarWinds Access Rights Manager 2023.2.2 and earlier allows remote attackers to execute code. The JsonSerializationHelper class deserializes user-supplied data without proper validation, enabling attacker-controlled code to run as SYSTEM. ZDI reports that the service requires authentication but that its existing authentication mechanism can be bypassed.
