Configuration API in EdgeXFoundry 2.1.0 and earlier exposes message bus credentials to local unauthenticated users
Advisory: GHSA-g63h-q855-vp3q
Aliases: CVE-2022-31066
Published: 2022-06-17T01:11:42Z
Severity: type: CVSS_V3
score: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L

### Impact
The /api/v2/config endpoint exposes message bus credentials to local unauthenticated users.  In security-enabled mode, message bus credentials are supposed to be kept in the EdgeX secret store and require authentication to access.  This vulnerability bypasses the access controls on message bus credentials when running in security-enabled mode.  (No credentials are required when running in security-disabled mode.)  As a result, attackers could intercept data or inject fake data into the EdgeX message bus.

### Patches
Users should upgrade to EdgeXFoundry Kamakura release (2.2.0) or to the June 2022 EdgeXFoundry LTS Jakarta release (2.1.1).
