CVE-2021-33504 1 Couchbase 1 Couchbase Server 2022-06-09 4.0 MEDIUM 4.9 MEDIUM
Couchbase Server before 7.1.0 has Incorrect Access Control.
CVE-2022-31022 1 Couchbase 1 Bleve 2022-06-09 2.1 LOW 5.5 MEDIUM
Bleve is a text indexing library for go. Bleve includes HTTP utilities under bleve/http package, that are used by its sample application. These HTTP methods pave way for exploitation of a node’s filesystem where the bleve index resides, if the user has used bleve’s own HTTP (bleve/http) handlers for exposing the access to the indexes. For instance, the CreateIndexHandler (`http/index_create.go`) and DeleteIndexHandler (`http/index_delete.go`) enable an attacker to create a bleve index (directory structure) anywhere where the user running the server has the write permissions and to delete recursively any directory owned by the same user account. Users who have used the bleve/http package for exposing access to bleve index without the explicit handling for the Role Based Access Controls(RBAC) of the index assets would be impacted by this issue. There is no patch for this issue because the http package is purely intended to be used for demonstration purposes. Bleve was never designed handle the RBACs, nor it was ever advertised to be used in that way. The collaborators of this project have decided to stay away from adding any authentication or authorization to bleve project at the moment. The bleve/http package is mainly for demonstration purposes and it lacks exhaustive validation of the user inputs as well as any authentication and authorization measures. It is recommended to not use bleve/http in production use cases.
CVE-2019-11495 1 Couchbase 1 Couchbase Server 2022-04-18 7.5 HIGH 9.8 CRITICAL
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.
CVE-2022-26311 1 Couchbase 1 Cloud Native Operator 2022-03-17 5.0 MEDIUM 7.5 HIGH
Couchbase Operator 2.2.x before 2.2.3 exposes Sensitive Information to an Unauthorized Actor. Secrets are not redacted in logs collected from Kubernetes environments.
CVE-2020-9039 1 Couchbase 1 Couchbase Server 2022-01-01 7.5 HIGH 9.8 CRITICAL
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.
CVE-2021-43963 1 Couchbase 1 Sync Gateway 2021-12-09 5.5 MEDIUM 8.1 HIGH
An issue was discovered in Couchbase Sync Gateway 2.7.0 through 2.8.2. The bucket credentials used to read and write data in Couchbase Server were insecurely being stored in the metadata within sync documents written to the bucket. Users with read access could use these credentials to obtain write access. (This issue does not affect clusters where Sync Gateway is authenticated with X.509 client certificates. This issue also does not affect clusters where shared bucket access is not enabled on Sync Gateway.)
CVE-2021-42763 1 Couchbase 1 Couchbase Server 2021-11-08 5.0 MEDIUM 7.5 HIGH
Couchbase Server before 6.6.3 and 7.x before 7.0.2 stores Sensitive Information in Cleartext. The issue occurs when the cluster manager forwards a HTTP request from the pluggable UI (query workbench etc) to the specific service. In the backtrace, the Basic Auth Header included in the HTTP request, has the "@" user credentials of the node processing the UI request.
CVE-2021-37842 1 Couchbase 1 Couchbase Server 2021-11-08 5.0 MEDIUM 7.5 HIGH
metakv in Couchbase Server 7.0.0 uses Cleartext for Storage of Sensitive Information. Remote Cluster XDCR credentials can get leaked in debug logs. Config key tombstone purging was added in Couchbase Server 7.0.0. This issue happens when a config key, which is being logged, has a tombstone purger time-stamp attached to it.
CVE-2021-35944 1 Couchbase 1 Couchbase Server 2021-10-02 5.0 MEDIUM 7.5 HIGH
Couchbase Server 6.5.x, 6.6.x through 6.6.2, and 7.0.0 has a Buffer Overflow. A specially crafted network packet sent from an attacker can crash memcached.
CVE-2021-35945 1 Couchbase 1 Couchbase Server 2021-10-02 5.0 MEDIUM 7.5 HIGH
Couchbase Server 6.5.x, 6.6.0 through 6.6.2, and 7.0.0, has a Buffer Overflow. A specially crafted network packet sent from an attacker can crash memcached.
CVE-2021-25643 1 Couchbase 1 Couchbase Server 2021-09-09 4.0 MEDIUM 4.9 MEDIUM
An issue was discovered in Couchbase Server 5.x and 6.x before 6.5.2 and 6.6.x before 6.6.2. Internal users with administrator privileges, @cbq-engine-cbauth and @index-cbauth, leak credentials in cleartext in the indexer.log file when they make a /listCreateTokens, /listRebalanceTokens, or /listMetadataTokens call.
CVE-2019-11465 1 Couchbase 1 Couchbase Server 2021-07-21 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2021-27924 1 Couchbase 1 Couchbase Server 2021-05-26 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Couchbase Server 6.x through 6.6.1. The Couchbase Server UI is insecurely logging session cookies in the logs. This allows for the impersonation of a user if the log files are obtained by an attacker before a session cookie expires.
CVE-2021-31158 1 Couchbase 1 Couchbase Server 2021-05-25 4.0 MEDIUM 6.5 MEDIUM
In the Query Engine in Couchbase Server 6.5.x and 6.6.x through 6.6.1, Common Table Expression queries were not correctly checking the user's permissions, allowing read-access to resources beyond what those users were explicitly allowed to access.
CVE-2021-25644 1 Couchbase 1 Couchbase Server 2021-05-25 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Couchbase Server 5.x and 6.x through 6.6.1 and 7.0.0 Beta. Incorrect commands to the REST API can result in leaked authentication information being stored in cleartext in the debug.log and info.log files, and is also shown in the UI visible to administrators.
CVE-2021-25645 1 Couchbase 1 Couchbase Server 2021-05-24 2.1 LOW 4.4 MEDIUM
An issue was discovered in Couchbase Server before 6.0.5, 6.1.x through 6.5.x before 6.5.2, and 6.6.x before 6.6.1. An internal user with administrator privileges, @ns_server, leaks credentials in cleartext in the cbcollect_info.log, debug.log, ns_couchdb.log, indexer.log, and stats.log files. NOTE: updating the product does not automatically address leaks that occurred in the past.
CVE-2020-24719 1 Couchbase 1 Couchbase Server 2020-11-30 10.0 HIGH 9.8 CRITICAL
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.
CVE-2019-11496 1 Couchbase 1 Couchbase Server 2020-08-24 6.4 MEDIUM 9.1 CRITICAL
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.
CVE-2019-11466 1 Couchbase 1 Couchbase Server 2020-08-24 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2019-11467 1 Couchbase 1 Couchbase Server 2020-08-24 7.8 HIGH 7.5 HIGH
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.
