Contrail Service Orchestration: Authentication Bypass Using an Alternate Path or Channel
CVE-2022-22189 is a high-severity authentication bypass using an alternate path or channel vulnerability in Contrail Service Orchestration from Juniper Networks, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 6.0.0 Patch v3 as the first without the flaw, so updating Contrail Service Orchestration to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.23% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
How developers prevent this class of flaw
- Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
