Dictionary Attack in Cockroachdb
How Dictionary Attack Manifests in Cockroachdb
Dictionary attacks against CockroachDB exploit the database's authentication mechanisms and user enumeration capabilities. Unlike traditional SQL databases where authentication is often handled at the application layer, CockroachDB provides built-in SQL-level authentication that can be targeted directly.
The primary attack vector involves brute-forcing the root user or other database users by repeatedly attempting login connections. CockroachDB's default configuration allows unlimited authentication attempts, making it vulnerable to credential stuffing attacks using common password dictionaries.
Cockroachdb-Specific Detection
Detecting dictionary attacks in CockroachDB requires monitoring authentication logs and connection patterns. CockroachDB writes authentication failures to the cockroach.log file by default, but this requires log analysis to identify attack patterns.
Cockroachdb-Specific Remediation
Remediating dictionary attack vulnerabilities in CockroachDB requires a multi-layered approach using the database's native security features. The most effective protection is implementing connection throttling and authentication rate limiting at the database level.
Frequently Asked Questions
Can CockroachDB automatically lock accounts after failed login attempts?
CockroachDB does not have built-in account lockout functionality. You need to implement this through custom logic using stored procedures, external authentication services, or network-level controls like connection limits and rate limiting.Does middleBrick scan CockroachDB instances directly?
Yes, middleBrick can scan any SQL endpoint including CockroachDB instances. The scanner tests authentication mechanisms, attempts to enumerate users, and checks for information disclosure vulnerabilities specific to the database's response patterns.
