The SolarWinds Orion API is vulnerable to an authentication bypass that could allow a remote attacker to execute API commands. This vulnerability could allow a remote attacker to bypass authentication and execute API commands which may result in a compromise of the SolarWinds instance. SolarWinds Orion Platform versions 2019.4 HF 5, 2020.2 with no hotfix installed, and 2020.2 HF 1 are affected.

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.

SolarWinds Platform was susceptible to the Deserialization of Untrusted Data. This vulnerability allows a remote adversary with Orion admin-level account access to SolarWinds Web Console to execute arbitrary commands.

The SolarWinds Platform was susceptible to the Local Privilege Escalation Vulnerability. This vulnerability allows a local adversary with a valid system user account to escalate local privileges.

The SolarWinds Platform was susceptible to the Incorrect Input Neutralization Vulnerability. This vulnerability allows a remote adversary with a valid SolarWinds Platform account to append URL parameters to inject HTML.

The custom menu item options page in SolarWinds Orion Platform before 2020.2.5 allows Reverse Tabnabbing in the context of an administrator account.

SolarWinds Orion Platform before 2020.2.5 allows stored XSS attacks by an administrator on the Customize View page.

SolarWinds Orion Platform before 2020.2.4, as used by various SolarWinds products, installs and uses a SQL Server backend, and stores database credentials to access this backend in a file readable by unprivileged users. As a result, any user having access to the filesystem can read database login details from that file, including the login name and its associated password. Then, the credentials can be used to get database owner access to the SWNetPerfMon.DB database. This gives access to the data collected by SolarWinds applications, and leads to admin access to the applications by inserting or changing authentication data stored in the Accounts table of the database.

The SolarWinds Platform was susceptible to the Incorrect Comparison Vulnerability. This vulnerability allows users with administrative access to SolarWinds Web Console to execute arbitrary commands with NETWORK SERVICE privileges.

The SolarWinds Platform was susceptible to the Incorrect Comparison Vulnerability. This vulnerability allows users with administrative access to SolarWinds Web Console to execute arbitrary commands with NETWORK SERVICE privileges.
