CVE-2021-28674: SolarWinds Orion Platform

Medium severity, CVSS 5.4. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products
