Chromium: CVE-2023-3079 Type Confusion in V8

Chromium: CVE-2023-2033 Type Confusion in V8

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.

A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.

End of life: 10/31/2028, Latest version: 8.0.2

An issue was discovered in Couchbase Sync Gateway before 3.2.6. In sgcollectinfooptions.log and syncgateway.log, there are cleartext passwords in redacted and unredacted output.

The Couchbase .NET SDK (client library) before 3.7.1 does not properly enable hostname verification for TLS certificates. In fact, the SDK was also using IP addresses instead of hostnames due to a configuration option that was incorrectly enabled by default.

Impact What kind of vulnerability is it? Who is impacted?

Bleve includes HTTP utilities under bleve/http package, that are used by its sample application. (https://github.com/blevesearch/bleve-explorer) These HTTP methods paves 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/indexcreate.go) and DeleteIndexHandler (http/indexdelete.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.

Patches Has the problem been patched? What versions should users upgrade to?

No. The http package is purely intended to be used for demonstration purposes. And bleve is never designed to be handling the RBACs or it was ever advertised to be used in that way. Hence the collaborators of this project have decided to stay away from adding any authentication or authorization to bleve project at the moment.

Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading?

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. So it is recommended to not use that in production use cases.

A security issue has been discovered in Couchbase Server before 7.6.4 and fixed in v.7.6.4 and v.7.2.7 for Windows that could allow unauthorized access to sensitive files. Depending on the level of privileges, this vulnerability may grant access to files such as /etc/passwd or /etc/shadow.

An issue was discovered in Couchbase Server 6.6.x through 7.2.0, before 7.1.5 and 7.2.1. Unauthenticated users may cause memcached to run out of memory via large commands.

Couchbase Server 7.1.x and 7.2.x before 7.2.4 does not require authentication for the /admin/stats and /admin/vitals endpoints on TCP port 8093 of localhost.

An issue was discovered in Couchbase Server through 7.2.2. A data reader may cause a denial of service (application exist) because of the OOM killer.

An issue was discovered in Couchbase Server 7.6.x through 7.6.3. A user with the securityadminlocal role can create a new user in a group that has the admin role.

An issue was discovered in Couchbase Server before 7.2.x before 7.2.4. otpCookie is shown with full admin on pools/default/serverGroups and engageCluster2.

An issue was discovered in Couchbase Server before 7.2.4. nsserver admin credentials are leaked in encoded form in the diag.log file. The earliest affected version is 7.1.5.

An issue was discovered in Couchbase Server before 7.2.4. An attacker can bypass SQL++ N1QL cURL host restrictions.

An issue was discovered in Couchbase Server before 7.2.4. SQL++ cURL calls to /diag/eval are not sufficiently restricted.

An issue was discovered in Couchbase Server through 7.1.4 before 7.1.5 and before 7.2.1. There are Unauthenticated RMI Service Ports Exposed in Analytics.

An issue was discovered in Couchbase Server before 7.2.4. cURL calls to /diag/eval are not sufficiently restricted.

An issue was discovered in Couchbase Server through 7.2.2. A data reader may cause a denial of service (outage of reader threads).

An issue was discovered in Couchbase Server 6.5.x and 6.6.x before 6.6.6, 7.x before 7.0.5, and 7.1.x before 7.1.2. During the start-up of a Couchbase Server node, there is a small window of time (before the cluster management authentication has started) where an attacker can connect to the cluster manager using default credentials.

An issue was discovered in Couchbase Server 7.x before 7.0.5 and 7.1.x before 7.1.2. A crafted HTTP REST request from an administrator account to the Couchbase Server Backup Service can exhaust memory resources, causing the process to be killed, which can be used for denial of service.

Couchbase Server before 6.6.6, 7.x before 7.0.5, and 7.1.x before 7.1.2 exposes Sensitive Information to an Unauthorized Actor.

Couchbase Server 7.6.x before 7.6.2, 7.2.x before 7.2.6, and all earlier versions allows HTTP Host header injection.

An issue was discovered in Couchbase Server before 7.2.5 and 7.6.0 before 7.6.1. It does not ensure that credentials are negotiated with the Key-Value (KV) service using SCRAM-SHA when remote link encryption is configured for Half-Secure.

In Couchbase Server 5 through 7 before 7.1.4, the nsstats endpoint is accessible without authentication.

Couchbase Server before 7.2.4 has a private key leak in goxdcr.log.

An issue was discovered in Couchbase Server 7.2.0. There is a private key leak in debug.log while adding a pre-7.0 node to a 7.2 cluster.

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.)
