Vulnerability from github – Published: 2022-05-24 16:55 – Updated: 2022-05-24 16:55

Details

Couchbase Server 5.1.1 generates insufficiently random numbers. The product hosts many network services by default. One of those services is an epmd service, which allows for node integration between Erlang instances. This service is protected by a single 16-character password. Unfortunately, this password is not generated securely due to an insufficient random seed, and can be reasonably brute-forced by an attacker to execute code against a remote system.

Severity

9.8 (Critical)

CVE-2019-11495 (GCVE-0-2019-11495)

Vulnerability from cvelistv5 – Published: 2019-09-10 17:16 – Updated: 2024-08-04 22:55

Summary

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.

Severity

No CVSS data available.
