Detailsinfo

A vulnerability was found in One Identity OneLogin Active Directory Connector up to 6.1.4. It has been classified as very critical. This affects some unknown functionality of the file /api/adc/v4/configuration of the component JWT Signing Key Handler. The manipulation with an unknown input leads to a authentication spoofing vulnerability. CWE is classifying the issue as CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A cryptographic authentication bypass vulnerability exists in OneLogin AD Connector prior to 6.1.5 due to the exposure of a tenant’s SSO JWT signing key via the /api/adc/v4/configuration endpoint. An attacker in possession of the signing key can craft valid JWT tokens impersonating arbitrary users within a OneLogin tenant. The tokens allow authentication to the OneLogin SSO portal and all downstream applications federated via SAML or OIDC. This allows full unauthorized access across the victim’s SaaS environment.

The weakness was disclosed by SpecterOps. It is possible to read the advisory at support.onelogin.com. This vulnerability is uniquely identified as CVE-2025-34063 since 04/15/2025.
