terraform-provider-power-platform: Insertion of Sensitive Information into Log File
CVE-2024-47083 is a high-severity insertion of sensitive information into log file vulnerability in terraform-provider-power-platform from Microsoft, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 3.0.0 as the first without the flaw, so updating terraform-provider-power-platform to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.55% chance of exploitation within 30 days, higher than 76% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update terraform-provider-power-platform to 3.0.0 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Power Platform Terraform Provider allows managing environments and other resources within Power Platform. Versions prior to 3.0.0 have an issue in the Power Platform Terraform Provider where sensitive information, specifically the `client_secret` used in the service principal authentication, may be exposed in logs. This exposure occurs due to an error in the logging code that causes the `client_secret` to not be properly masked when logs are persisted or viewed. Users should upgrade to version 3.0.0 to receive a patched version of the provider that removes all logging of sensitive content. Users who have used this provider with the affected versions should take the following additional steps to mitigate the risk: Immediately rotate the `client_secret` for any service principal that has been configured using this Terraform provider. This will invalidate any potentially exposed secrets. Those who have set the `TF_LOG_PATH` environment variable or configured Terraform to persist logs to a file or an external system, consider disabling this until they have updated to a fixed version of the provider. Those who have existing logs that may contain the `client_secret` should remove or sanitize these logs to prevent unauthorized access. This includes logs on disk, in monitoring systems, or in logging services.

The underlying weakness: Insertion of Sensitive Information into Log File
The product writes sensitive information to a log file.
How developers prevent this class of flaw
- Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
- Remove debug log files before deploying the application into production.
- Protect log files against unauthorized read/write.
