The cookie used for intra-node communication was not generated securely. Couchbase Server uses erlang:now() to seed the PRNG which results in a small search space for potential random seeds that could then be used to brute force the cookie and execute code against a remote system.

The /settings REST endpoint exposed by the projector process is an endpoint that administrators can use for various tasks such as updating configuration and collecting performance profiles. The endpoint was unauthenticated and has been updated to only allow authenticated users to access these administrative APIs. Recognition: Apple Security team

Secondary indexing encodes the entries to be indexed using collatejson. When index entries contained certain characters like t, , it caused a buffer overrun as the encoded string would be much larger than accounted for, causing the indexer service to crash and restart. This has been remedied now to ensure the buffer always grows as needed for any input. Recognition: D-Trust GmbH

When an invalid remote cluster certificate was entered as part of the reference creation, XDCR did not parse and check the certificate signature. It then accepted the invalid certificate and attempted to use it to establish future connections to the remote cluster. This has been fixed. XDCR now checks the validity of the certificate thoroughly and prevents a remote cluster reference from being created with an invalid certificate.

In versions of Couchbase Server prior to 5.0, the bucket named “default” was a special bucket that allowed read and write access without authentication. As part of 5.0, the behavior of all buckets including “default” were changed to only allow access by authenticated users with sufficient authorization. However, users were allowed unauthenticated and unauthorized access to the “default” bucket if the properties of this bucket were edited. This has been fixed.
