Summary

Weave GitOps Terraform Controller Information Disclosure Vulnerability

Details

Impact

A vulnerability has been identified in Weave GitOps Terraform Controller which could allow an authenticated remote attacker to view sensitive information. This vulnerability stems from Weave GitOps Terraform Runners (tf-runner), where sensitive data is inadvertently printed - potentially revealing sensitive user data in their pod logs. In particular, functions tfexec.ShowPlan, tfexec.ShowPlanRaw, and tfexec.Output are implicated when the tfexec object set its Stdout and Stderr to be os.Stdout and os.Stderr.

An unauthorized remote attacker could exploit this vulnerability by accessing these prints of sensitive information, which may contain configurations or tokens that could be used to gain unauthorized control or access to resources managed by the Terraform controller.

A successful exploit could allow the attacker to utilize this sensitive data, potentially leading to unauthorized access or control of the system.

Patches

This vulnerability has been addressed in Weave GitOps Terraform Controller versions v0.14.4 and v0.15.0-rc.5. Users are urged to upgrade to one of these versions to mitigate the vulnerability.

The patches for this vulnerability are found in: - this commit: 9708fda28ccd0466cb0a8fd409854ab4d92f7dca - this commit: 6323b355bd7f5d2ce85d0244fe0883af3881df4e - this commit: 28282bc644054e157c3b9a3d38f1f9551ce09074 - and this commit: 98a0688036e9dbcf43fa84960d9a1ef3e09a69cf

Workarounds

As a temporary measure until the patch can be applied, users can add the environment variable DISABLE_TF_LOGS to the tf-runners via the runner pod template of the Terraform Custom Resource. This will prevent the logging of sensitive information and mitigate the risk of this vulnerability.
