CWE-ID: CWE-287

Exploitation vector: Network

Exploit availability: Yes

Vulnerable software:
Orion Platform
Server applications / Remote management servers, RDP, SSH

Vendor: SolarWinds

Description

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.
