==========================================
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

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.
