CVE-2024-58375 opentofu CVE debrief

Who should care

Defenders and administrators using OpenTofu versions 1.8.0 through 1.8.2 should assess their exposure and prioritize remediation. This includes performing inventory checks, verifying system configurations, and reviewing compensating controls for exposed systems while remediation is scheduled and verified.

Why it matters

CVE-2024-58375 exposes sensitive variables in OpenTofu configurations. Defenders should prioritize remediation, perform inventory checks, and verify system configurations.

• Potential exposure of sensitive information
• Need for inventory checks and remediation prioritization
• Verification of system configurations and access controls

Technical summary

The vulnerability in OpenTofu allows sensitive variables and locals to be exposed through static evaluation of module sources, versions, and backend configurations. This issue is fixed in OpenTofu 1.8.3, which introduces explicit errors to prevent the use of sensitive values in these contexts. Affected versions include OpenTofu 1.8.0 through 1.8.2, and defenders should prioritize upgrading to OpenTofu 1.8.3 or applying compensating controls to restrict access to sensitive configurations. Inventory checks are necessary to identify potentially affected systems.

Defensive priority

Defenders should prioritize upgrading to OpenTofu 1.8.3 or applying compensating controls to restrict access to sensitive configurations. Inventory checks are necessary to identify potentially affected systems.

Recommended defensive actions

• Upgrade to OpenTofu 1.8.3 or later
• Restrict access to sensitive configurations
• Perform inventory checks for potentially affected systems
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, additional information on exploitation or affected systems is limited. Defenders should verify system configurations, perform inventory checks, and assess potential exposure. The vulnerability affects OpenTofu versions 1.8.0 through 1.8.2, and explicit errors are introduced in OpenTofu 1.8.3 to prevent sensitive value exposure.
