Security Bulletin

This security bulletin contains one critical risk vulnerability.

1) Improper Authentication

EUVDB-ID: #VU49151

Risk: Critical


CVE-ID: CVE-2020-10148

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: Yes


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests within the SolarWinds Orion API. If an attacker appends a PathInfo parameter of WebResource.adx, ScriptResource.adx, i18n.ashx, or Skipi18n to a request to a SolarWinds Orion server, SolarWinds may set the SkipAuthorization flag, which may allow the API request to be processed without requiring authentication. This vulnerability could allow a remote non-authenticated attacker to bypass authentication and execute API commands which may result in a compromise of the SolarWinds instance.

Note, this vulnerability is dubbed SUPERNOVA and is being exploited in the wild.
