Exposed Erlang Cookie could lead to Remote Command Execution (RCE) attack

CVE-2020-24719 9.8 - Critical - November 12, 2020

Exposed Erlang Cookie could lead to Remote Command Execution (RCE) attack. Communication between Erlang nodes is done by exchanging a shared secret (aka "magic cookie"). There are cases where the magic cookie is included in the content of the logs. An attacker can use the cookie to attach to an Erlang node and run OS level commands on the system running the Erlang node. Affects version: 6.5.1. Fix version: 6.6.0.

Shell injection

CVE-2020-9042 8.8 - High - June 08, 2020

Session Riding

Couchbase Server 4.0.0, 4.1.0, 4.1.1, 4.5.0, 4.5.1, 4.6.0 through 4.6.5, 5.0.0, 5.1.1, 5.5.0 and 5.5.1 have Insecure Permissions for the projector and indexer REST endpoints (they allow unauthenticated access).The /settings REST endpoint exposed by the projector process is an endpoint

CVE-2020-9039 9.8 - Critical - February 22, 2020

Couchbase Server 4.0.0, 4.1.0, 4.1.1, 4.5.0, 4.5.1, 4.6.0 through 4.6.5, 5.0.0, 5.1.1, 5.5.0 and 5.5.1 have Insecure Permissions for the projector and indexer REST endpoints (they allow unauthenticated access).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.

Incorrect Default Permissions

In Couchbase Server 5.0.0

CVE-2019-11497 7.5 - High - September 10, 2019

In Couchbase Server 5.0.0, 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 in version 5.5.0. XDCR now checks the validity of the certificate thoroughly and prevents a remote cluster reference from being created with an invalid certificate.

Improper Certificate Validation

In versions of Couchbase Server prior to 5.0, the bucket named "default" was a special bucket

CVE-2019-11496 9.1 - Critical - September 10, 2019

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 in versions 5.1.0 and 5.5.0.

Missing Authentication for Critical Function

In Couchbase Server 5.1.1, the cookie used for intra-node communication was not generated securely

CVE-2019-11495 9.8 - Critical - September 10, 2019

In Couchbase Server 5.1.1, 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. This has been fixed in version 6.0.0.

PRNG

In Couchbase Server 4.6.3 and 5.5.0, secondary indexing encodes the entries to be indexed using collatejson

CVE-2019-11467 7.5 - High - September 10, 2019

In Couchbase Server 4.6.3 and 5.5.0, secondary indexing encodes the entries to be indexed using collatejson. When index entries contain certain characters like \t, <, >, it caused buffer overrun as encoded string would be much larger than accounted for, causing indexer service to crash and restart. This has been remedied in versions 5.1.2 and 5.5.2 to ensure buffer always grows as needed for any input.

Buffer Overflow

In Couchbase Server 6.0.0 and 5.5.0, the eventing service exposes system diagnostic profile via an HTTP endpoint

CVE-2019-11466 5.3 - Medium - September 10, 2019

In Couchbase Server 6.0.0 and 5.5.0, the eventing service exposes system diagnostic profile via an HTTP endpoint that does not require credentials on a port earmarked for internal traffic only. This has been remedied in version 6.0.1 and now requires valid credentials to access.

Missing Authentication for Critical Function

An issue was discovered in Couchbase Server 5.5.x through 5.5.3 and 6.0.0

CVE-2019-11465 5.3 - Medium - September 10, 2019

An issue was discovered in Couchbase Server 5.5.x through 5.5.3 and 6.0.0. The Memcached "connections" stat block command emits a non-redacted username. The system information submitted to Couchbase as part of a bug report included the usernames for all users currently logged into the system even if the log was redacted for privacy. This has been fixed (in 5.5.4 and 6.0.1) so that usernames are tagged properly in the logs and are hashed out when the logs are redacted.

Side Channel Attack

Some enterprises require that REST API endpoints include security-related headers in REST responses

CVE-2019-11464 6.1 - Medium - September 10, 2019

Some enterprises require that REST API endpoints include security-related headers in REST responses. Headers such as X-Frame-Options and X-Content-Type-Options are generally advisable, however some information security professionals additionally look for X-Permitted-Cross-Domain-Policies and X-XSS-Protection, which are more generally applicable to HTML endpoint, to be included too. These headers were not included in Couchbase Server 5.5.0 and 5.1.2 . They are now included in version 6.0.2 in responses from the Couchbase Server Views REST API (port 8092).

XSS

Couchbase Server exposed the '/diag/eval' endpoint which by default is available on TCP/8091 and/or TCP/18091

CVE-2018-15728 8.8 - High - August 24, 2018

Couchbase Server exposed the '/diag/eval' endpoint which by default is available on TCP/8091 and/or TCP/18091. Authenticated users that have 'Full Admin' role assigned could send arbitrary Erlang code to the 'diag/eval' endpoint of the API and the code would subsequently be executed in the underlying operating system with privileges of the user which was used to start Couchbase. Affects Version: 4.0.0, 4.1.2, 4.5.1, 5.0.0, 4.6.5, 5.0.1, 5.1.1, 5.5.0, 5.5.1. Fix Version: 6.0.0, 5.5.2
