Arch Linux Security Advisory ASA-202112-12 ========================================== Severity: High Date : 2021-12-11 CVE-ID : CVE-2021-41090 Package : grafana-agent Type : information disclosure Remote : Yes Link : https://security.archlinux.org/AVG-2614 Summary ======= The package grafana-agent before version 0.21.2-1 is vulnerable to information disclosure. Resolution ========== Upgrade to 0.21.2-1. # pacman -Syu "grafana-agent>=0.21.2-1" The problem has been fixed upstream in version 0.21.2. Workaround ========== None. Description =========== A security issue has been found in Grafana Agent before version 0.21.2. Some inline secrets are exposed in plaintext over the Grafana Agent HTTP server: - Inline secrets for metrics instance configs in the base YAML file are exposed at /-/config - Inline secrets for integrations are exposed at /-/config - Inline secrets for Consul ACL tokens and ETCD basic auth when configured for the scraping service at /-/config. - Inline secrets for the Kafka receiver for OpenTelemetry-Collector tracing at /-/config. - Inline secrets for metrics instance configs loaded from the scraping service are exposed at /agent/api/v1/configs/{name}. Inline secrets will be exposed to anyone being able to reach these endpoints. Secrets found in these sections are used for: - Delivering metrics to a Prometheus Remote Write system - Authenticating against a system for discovering Prometheus targets - Authenticating against a system for collecting metrics (scrape_configs and integrations) - Authenticating against a Consul or ETCD for storing configurations to distribute in scraping service mode - Authenticating against Kafka for receiving traces Non-inlined secrets, such as *_file-based secrets, are not impacted by this vulnerability. Impact ====== A remote attacker could disclose inline secrets over the Grafana Agent HTTP server.
