Name of the Vulnerable Software and Affected Versions CometD versions prior to 5.0.11, 6.0.6, and 7.0.6

Description CometD is a scalable comet implementation for web messaging. In versions prior to 5.0.11, 6.0.6, and 7.0.6, internal usage of Oort and Seti channels is improperly authorized, allowing any remote user to 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.

Recommendations For versions prior to 5.0.11, update to version 5.0.11. For versions prior to 6.0.6, update to version 6.0.6. For versions prior to 7.0.6, update to version 7.0.6. As a temporary workaround, consider installing a custom SecurityPolicy that forbids subscription and publishing to remote, non-Oort, sessions on Oort and Seti channels.
