Detailsinfo

A vulnerability, which was classified as very critical, was found in open-metadata OpenMetadata up to 1.2.3. Affected is the function getUserPrincipal of the file /api/v1. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. The `JwtFilter` handles the API authentication by requiring and verifying JWT tokens. When a new request comes in, the request's path is checked against this list. When the request's path contains any of the excluded endpoints the filter returns without validating the JWT. Unfortunately, an attacker may use Path Parameters to make any path contain any arbitrary strings. For example, a request to `GET /api/v1;v1%2fusers%2flogin/events/subscriptions/validation/condition/111` will match the excluded endpoint condition and therefore will be processed with no JWT validation allowing an attacker to bypass the authentication mechanism and reach any arbitrary endpoint, including the ones listed above that lead to arbitrary SpEL expression injection. This bypass will not work when the endpoint uses the `SecurityContext.getUserPrincipal()` since it will return `null` and will throw an NPE. This issue may lead to authentication bypass and has been addressed in version 1.2.4. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as `GHSL-2023-237`.
