Summary

SQL Injection in Couchbase Sync Gateway

Details

The Couchbase Sync Gateway 2.1.2 in combination with a Couchbase Server is affected by a previously undisclosed N1QL-injection vulnerability in the REST API. An attacker with access to the public REST API can insert additional N1QL statements through the parameters ?startkey? and ?endkey? of the ?_all_docs? endpoint.

Severity ?

9.8 (Critical)

CVE-2019-9039 (GCVE-0-2019-9039)

Vulnerability from cvelistv5 – Published: 2019-06-26 18:55 – Updated: 2024-08-04 21:38

Summary

In Couchbase Sync Gateway 2.1.2, an attacker with access to the Sync Gateway’s public REST API was able to issue additional N1QL statements and extract sensitive data or call arbitrary N1QL functions through the parameters "startkey" and "endkey" on the "_all_docs" endpoint. By issuing nested queries with CPU-intensive operations they may have been able to cause increased resource usage and denial of service conditions. The _all_docs endpoint is not required for Couchbase Mobile replication and external access to this REST endpoint has been blocked to mitigate this issue. This issue has been fixed in versions 2.5.0 and 2.1.3.

Severity ?

No CVSS data available.
