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.
