Name of the Vulnerable Software and Affected Versions: SolarWinds Orion Platform version 2020.2.1

Description: This issue allows remote attackers to create arbitrary files on affected installations. Although authentication is required to exploit this issue, the existing authentication mechanism can be bypassed. The specific flaw exists within VulnerabilitySettings.aspx. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this issue to execute arbitrary code in the context of SYSTEM.

Recommendations: For SolarWinds Orion Platform version 2020.2.1, as a temporary workaround, consider disabling access to the VulnerabilitySettings.aspx page until a patch is available. Restrict access to file operations to minimize the risk of exploitation. Avoid using user-supplied paths in file operations until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this issue.
