Detailsinfo

A vulnerability was found in Couchbase Server 5.1.1. It has been classified as critical. This affects some unknown functionality of the component epmd Service. The manipulation with an unknown input leads to a code injection vulnerability (PRNG). CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared 09/10/2019. This vulnerability is uniquely identified as CVE-2019-11495 since 04/23/2019. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
