OneLogin AD Connector API Credential and Signing Key Exposure

An information disclosure vulnerability exists in OneLogin AD Connector versions prior to 6.1.5 via the /api/adc/v4/configuration endpoint. An attacker with access to a valid directory_token—which may be retrievable from host registry keys or improperly secured logs—can retrieve a plaintext response disclosing sensitive credentials. These may include an API key, AWS IAM access and secret keys, and a base64-encoded JWT signing key used in the tenant’s SSO IdP configuration.

OneLogin AD Connector Log S3 Bucket Hijack Leading to Cross-Tenant Data Leakage

A cloud infrastructure misconfiguration in OneLogin AD Connector results in log data being sent to a hardcoded S3 bucket (onelogin-adc-logs-production) without validating bucket ownership. An attacker who registers this unclaimed bucket can begin receiving log files from other OneLogin tenants. These logs may contain sensitive data such as directory tokens, user metadata, and environment configuration. This enables cross-tenant leakage of secrets, potentially allowing JWT signing key recovery and user impersonation.
