garden: Missing Authentication for Critical Functionality
CVE-2022-24829 is a critical-severity missing authentication for critical functionality vulnerability in garden from Garden-io, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected garden versions: < 0.12.39. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.35% chance of exploitation within 30 days, higher than 72% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of garden you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
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 underlying weakness: Missing Authentication for Critical Functionality
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
