Advisory: SB2020122801 - Authentication bypass in SolarWinds Orion API
Vulnerable component: Orion Platform
CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C
CWE-ID: CWE-287 - Improper Authentication
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
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.
