Security Domain Hosts Enumeration via Unauthenticated GET Request

Executive Summary

CVE-2026-53682 is an information disclosure vulnerability in the Dogtag Certificate Authority (CA) REST API. An unauthenticated attacker can query the endpoint GET /ca/rest/securityDomain/hosts to retrieve a structured response listing internal PKI/CA hosts and their roles. This exposes the security domain topology and participating subsystems without requiring authentication or a session.

Detection Guidance

To detect this vulnerability, check if the endpoint GET /ca/rest/securityDomain/hosts is accessible without authentication. Use curl to query the endpoint: curl -v http://<target>/ca/rest/securityDomain/hosts. If the endpoint returns a structured response listing internal PKI/CA hosts and roles, the system is vulnerable.

Impact Analysis

This vulnerability allows attackers to enumerate internal infrastructure, identify high-value targets, and facilitate follow-on attacks like Server-Side Request Forgery (SSRF), pivoting, or phishing. It exposes sensitive hostnames and roles that could aid in reconnaissance or targeted attacks against the PKI/CA environment.

Mitigation Strategies

Immediately restrict access to the GET /ca/rest/securityDomain/hosts endpoint by implementing authentication or removing unauthenticated access. Mask or remove version and topology details from the API response to prevent information disclosure. Apply patches or updates from the vendor if available.
