Overview

CVE-2022-24721 is a high-severity vulnerability. It was published on March 15, 2022 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

CometD is a scalable comet implementation for web messaging. In any version prior to 5.0.11, 6.0.6, and 7.0.6, internal usage of Oort and Seti channels is improperly authorized, so any remote user could subscribe and publish to those channels. By subscribing to those channels, a remote user may be able to watch cluster-internal traffic that contains other users' (possibly sensitive) data. By publishing to those channels, a remote user may be able to create/modify/delete other user's data and modify the cluster structure. A fix is available in versions 5.0.11, 6.0.6, and 7.0.6. As a workaround, install a custom `SecurityPolicy` that forbids subscription and publishing to remote, non-Oort, sessions on Oort and Seti channels.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
