CVE-2023-45140

MEDIUM

ovh/the-bastion < 3.14.15 - Missing Authentication for SCP/SFTP via Group-Based JIT MFA Bypass

Title source: llm
STIX 2.1

Description

The Bastion provides authentication, authorization, traceability and auditability for SSH accesses. SCP and SFTP plugins don't honor group-based JIT MFA. Establishing a SCP/SFTP connection through The Bastion via a group access where MFA is enforced does not ask for additional factor. This abnormal behavior only applies to per-group-based JIT MFA. Other MFA setup types, such as Immediate MFA, JIT MFA on a per-plugin basis and JIT MFA on a per-account basis are not affected. This issue has been patched in version 3.14.15.
