CVE-2020-27871

This vulnerability allows remote attackers to create arbitrary files on affected installations of SolarWinds Orion Platform 2020.2.1. Although authentication is required to exploit this vulnerability, 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 vulnerability to execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-11902.
