CVE-2022-24829 in Garden
Summary
by MITRE • 04/12/2022
Garden is an automation platform for Kubernetes development and testing. In versions prior to 0.12.39 multiple endpoints did not require authentication. In some operating modes this allows for an attacker to gain access to the application erroneously. The configuration is leaked through the /api endpoint on the local server that is responsible for serving the Garden dashboard. At the moment, this server is accessible to 0.0.0.0 which makes it accessible to anyone on the same network (or anyone on the internet if they are on a public, static IP). This may lead to the ability to compromise credentials, secrets or environment variables. Users are advised to upgrade to version 0.12.39 as soon as possible. Users unable to upgrade should use a firewall blocking access to port 9777 from all untrusted network machines.

The vulnerability described in CVE-2022-24829 affects Garden, a Kubernetes automation platform designed for development and testing environments. This security flaw represents a critical authentication bypass issue that exposes multiple endpoints without proper access controls. The vulnerability exists in versions prior to 0.12.39 and stems from improper configuration of the local server that hosts the Garden dashboard. The affected system fails to enforce authentication mechanisms on several endpoints, creating a significant attack surface that can be exploited by unauthorized parties. This authentication weakness directly violates security best practices and creates opportunities for privilege escalation and data compromise within Kubernetes environments where Garden is deployed.
The technical implementation of this vulnerability manifests through the /api endpoint which serves as the primary interface for the Garden dashboard. This endpoint is configured to listen on 0.0.0.0, making it accessible from any network interface and potentially from the internet if public IP addresses are assigned. The configuration leak occurs because the server does not properly restrict access to its administrative interfaces, allowing any network entity to connect and potentially exploit the exposed endpoints. This misconfiguration creates a direct pathway for attackers to access sensitive information through the local server, bypassing intended security controls. The vulnerability's impact is amplified by the fact that it affects the core dashboard functionality, which typically contains access credentials, environment variables, and other sensitive configuration data that would normally be protected.
The operational impact of this vulnerability extends beyond simple unauthorized access to include potential credential theft, secret compromise, and environment variable exposure. Attackers who successfully exploit this vulnerability could gain access to Kubernetes cluster credentials, application secrets, and other sensitive operational data that would enable them to move laterally within the environment. This represents a significant risk to organizations using Garden for development and testing, as these environments often contain sensitive data and access tokens that could be leveraged for further attacks. The vulnerability's exposure through a public-facing interface means that attackers do not require physical access or network proximity to exploit the flaw, making it particularly dangerous in cloud and containerized environments where network boundaries may be less defined.
Organizations affected by this vulnerability should prioritize upgrading to version 0.12.39 which includes proper authentication controls and access restrictions. The recommended mitigation strategy involves implementing network-level controls through firewalls that block access to port 9777 from untrusted networks, effectively isolating the vulnerable service from external threats. This firewall approach serves as a temporary workaround while organizations plan their upgrade schedules. Security teams should also conduct immediate assessments of their Garden deployments to identify any systems running vulnerable versions and implement monitoring for suspicious access patterns. The vulnerability aligns with CWE-284 (Improper Access Control) and represents a clear violation of the principle of least privilege, as the service operates with unnecessary exposure that creates attack vectors for adversaries. From an ATT&CK framework perspective, this vulnerability maps to T1078 (Valid Accounts) and T1566 (Phishing) as attackers could leverage exposed credentials to establish persistent access and potentially move laterally within the environment.
