Predictable Node IDs and Incorrect Access Control in SolarWinds Orion Platform Allow Unauthorized Node Creation and Deletion

CVE-2021-28674 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L

The node management page in SolarWinds Orion Platform before 2020.2.5 HF1 allows an attacker to create or delete a node (outside of the attacker's perimeter) via an account with write permissions. This occurs because node IDs are predictable (with incrementing numbers) and the access control on Services/NodeManagement.asmx/DeleteObjNow is incorrect. To exploit this, an attacker must be authenticated and must have node management rights associated with at least one valid group on the platform.
