Security readout for executives and security teams
Plain-English summary
Terraform could send an Azure storage SAS token and Terraform state over unencrypted HTTP in affected versions. That matters because state files often contain sensitive infrastructure details or secrets, and a SAS token can grant access to Azure storage resources.
Executive priority
Prioritize remediation if legacy Terraform and Azure SAS-backed state were used in CI, shared networks, or environments with sensitive state. Otherwise, treat as a targeted legacy configuration risk.
Technical view
CVE-2019-19316 affects Terraform versions before 0.12.17 when using the Azure backend with a shared access signature. The reported issue is cleartext HTTP transmission of the SAS token and state snapshot. No CVSS, CWE, or detailed affected CPE data is provided in the bundle.
Likely exposure
Exposure is limited to organizations that used Terraform before 0.12.17 with the Azure backend authenticated by SAS. Risk depends on whether cleartext traffic crossed untrusted networks and what secrets existed in state.
Exploitation context
The provided sources do not state active exploitation, and the CVE is not marked KEV. The main concern is interception or observation of cleartext traffic carrying a SAS token and Terraform state data.
Researcher notes
The bundle provides a concise description but lacks CVSS, CWE, CPE, and detailed exploitation evidence. Analysis should stay scoped to Terraform before 0.12.17 with Azure backend SAS usage.
Mitigation direction
- Upgrade Terraform to 0.12.17 or later.
- Review HashiCorp advisory for vendor-specific guidance.
- Rotate Azure SAS tokens if affected traffic may have occurred.
- Review and rotate secrets stored in affected Terraform state.
- Limit SAS scope and lifetime where Azure backend SAS remains used.
Validation and detection
- Inventory Terraform versions used by developers and CI runners.
- Identify Azure backend configurations that used SAS authentication.
- Confirm affected workflows no longer run Terraform before 0.12.17.
- Review logs or network records for cleartext HTTP backend traffic.
- Assess affected state files for embedded credentials or sensitive outputs.
