Bulletin ID: HCSEC-2022-06
Affected Products / Versions: Terraform Enterprise v202112-1 through v202201-2; fixed in v202202-1.
Publication Date: February 23, 2022
Terraform Enterprise was configured to log inbound HTTP requests in a manner that may capture sensitive data. This vulnerability, CVE-2022-25374, was fixed in Terraform Enterprise v202202-1.
It was reported that TFE was writing newly-created or edited workspace variables to a log forwarding destination.
On investigation, it was determined that a traceability-related improvement within the application had an unintended side effect of logging HTTP request bodies, which in some cases included sensitive data. A sensitive data redaction mechanism that had been implemented previously was not fully effective against the logs in question.
The logs were being emitted by the
ptfe_atlas container within TFE, and retained locally within the TFE installation. A default installation does not forward any logs but, if TFE’s log forwarding feature was enabled, these logs may have been forwarded to the configured external destination/s.
The Terraform Enterprise application logging configuration has been modified to no longer capture HTTP request bodies, as was the case prior to v202112-1.
Customers running affected Terraform Enterprise versions should evaluate the risk associated with this issue and consider upgrading to Terraform Enterprise v202202-1 or newer. Please refer to Upgrading Terraform Enterprise for general guidance.
Customers should also evaluate their Terraform Enterprise deployments, workspaces, and log forwarding destinations for sensitive data that may have been captured, such as sensitive variables, and consider appropriate actions such as rotation of secrets.
