CVE-2023-5077Network attack vector

Permanent Google Cloud access via dropped IAM conditions

Published Sep 28, 2023 · Updated Sep 26, 2024

Privilege assignment error in HashiCorp Vault and Vault Enterprise before 1.13.0 allows remote authenticated users to remove GCP IAM conditions. The ChangedBindings function in plugin/iamutil/iam_policy.go builds a replacement IAM policy binding without copying the original Condition field. A user authorized to create or update a Google Cloud roleset can convert conditional, including expired, grants into permanent access.
