A security researcher stored XSS via a Help Server setting. This affects customers using Internet Explorer, because they do not support 'rel=noopener'.
Improper Access Control Tampering Vulnerability using ImportAlert function which can lead to a Remote Code Execution (RCE) from the Alerts Settings page.
This vulnerability allows attackers to impersonate users and perform arbitrary actions leading to a Remote Code Execution (RCE) from the Alerts Settings page.
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.
The Collector Service in SolarWinds Orion Platform before 2020.2.4 uses MSMQ (Microsoft Message Queue) and doesn't set permissions on its private queues. As a result, remote unauthenticated clients can send messages to TCP port 1801 that the Collector Service will process. Additionally, upon processing of such messages, the service deserializes them in insecure manner, allowing remote arbitrary code execution as LocalSystem.
