Required Configuration for Exploitation

All versions of CloudVision listed in the “Affected Software” section above are vulnerable to CVE-2023-24546 but the degree of severity varies based on the current version of CloudVision and the original version of CloudVision used to deploy the cluster.

In the 2021.1 and 2021.2 releases, a bug in the authorization layer gave certain types of clients read access to additional parts of the CloudVision database, including CloudVision configuration settings. In these releases the CVSS score is 7.6

In the 2021.3 train, 2022.1.0, 2022.1.1, 2022.2.0, 2022.2.1, and 2022.3.0 releases, there was a further bug in the authorization layer giving those same clients write access to additional parts of the CloudVision database. In these releases the CVSS score is 9.9

For clusters that were first deployed with the 2022.2.0 or 2022.2.1 releases, the CVSS score is 10.0
(CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L) due to an additional issue.

The overall impact is that a malicious actor with network access to the CloudVision cluster and the credentials for a specific type of account could read or write additional state in the CloudVision database, including telemetry and configuration state.
