Name of the Vulnerable Software and Affected Versions Couchbase Server version 6.0.3 Couchbase Sync Gateway versions prior to 2.7.1

Description The issue affects the Cluster management, views, query, and full-text search endpoints, making them vulnerable to a denial-of-service attack. This is due to the endpoints not aggressively terminating slow connections, which can be exploited through a Slowloris attack.

Recommendations For Couchbase Server version 6.0.3, update to a version that includes a fix for this issue. For Couchbase Sync Gateway versions prior to 2.7.1, update to version 2.7.1 or later to resolve the issue. As a temporary workaround, consider configuring the server to more aggressively terminate slow connections to minimize the risk of exploitation.
