Weave · Weave Gitops Terraform Controller · CVE-2023-34236
**Name of the Vulnerable Software and Affected Versions**
Weave GitOps Terraform Controller versions prior to v0.14.4
Weave GitOps Terraform Controller versions prior to v0.15.0-rc.5
**Description**
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.
**Recommendations**
To mitigate the vulnerability, upgrade to Weave GitOps Terraform Controller version v0.14.4 or v0.15.0-rc.5.
As a temporary measure until the patch can be applied, add the environment variable `DISABLE TF LOGS` to the tf-runners via the runner pod template of the Terraform Custom Resource to prevent the logging of sensitive information.
