Critical severity GitHub Reviewed Published May 14, 2022 to the GitHub Advisory Database • Updated Feb 21, 2024

Package

gomod github.com/hashicorp/terraform-provider-aws (Go)

Affected versions

< 1.14.0

Patched versions

1.14.0

Description

aws/resource_aws_iam_user_login_profile.go in the HashiCorp Terraform Amazon Web Services (AWS) provider through v1.12.0 has an inappropriate PRNG algorithm and seeding, which makes it easier for remote attackers to obtain access by leveraging an IAM account that was provisioned with a weak password.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
