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-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-2021-42763 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-2019-11467 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.
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-2020-9041 1 Couchbase 2 Couchbase Server, Sync Gateway 2020-06-11 5.0 MEDIUM 7.5 HIGH
In Couchbase Server 6.0.3 and Couchbase Sync Gateway through 2.7.0, the Cluster management, views, query, and full-text search endpoints are vulnerable to the Slowloris denial-of-service attack because they don't more aggressively terminate slow connections.
CVE-2020-9042 1 Couchbase 1 Couchbase Server 2020-06-11 6.8 MEDIUM 8.8 HIGH
In Couchbase Server 6.0, credentials cached by a browser can be used to perform a CSRF attack if an administrator has used their browser to check the results of a REST API request.
CVE-2019-11497 1 Couchbase 1 Couchbase Server 2019-09-26 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-11464 1 Couchbase 1 Couchbase Server 2019-09-26 4.3 MEDIUM 6.1 MEDIUM
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).
