Summary
Fixed CWE-732 (Incorrect Permission Assignment for Critical Resource) by setting
umask 077before writing Vault root token files to ensure they are created with 0600 permissions instead of world-readable 0644.Finding
The Vault demo scripts wrote root tokens to files without restrictive permissions. Under the default umask 022, these files were created as 0644 (world-readable), allowing any local user to obtain the Vault root token and gain unrestricted access to all secrets.
CVSS: 6.8 (CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N)
Remediation
Applied
umask 077before writing root token files in:projects/ccm-vault/vault-init-unseal.sh- Added umask before vault operator init outputscripts/vault/vault_ec2.yaml- Added umask before writing vault-init.json and vault-root-token.txtThis ensures files are created with 0600 permissions (read/write owner only), preventing unauthorized access.
