Vulnerability Data

In Eclipse Dataspace Components from version 0.2.1 to 0.6.2, in the EDC Connector component ( https://github.com/eclipse-edc/Connector ), an attacker might obtain OAuth2 client secrets from the vault. In Eclipse Dataspace Components from version 0.2.1 to 0.6.2, we have identified a…

security vulnerability in the EDC Connector component ( https://github.com/eclipse-edc/Connector ) regarding the OAuth2-protected data sink feature. When using a custom, OAuth2-protected data sink, the OAuth2-specific data address properties are resolved by the provider data plane. Problematically, the consumer-provided clientSecretKey, which indicates the OAuth2 client secret to retrieve from a secrets vault, is resolved in the context of the provider's vault, not the consumer. This secret's value is then sent to the tokenUrl, also consumer-controlled, as part of an OAuth2 client credentials grant. The returned access token is then sent as a bearer token to the data sink URL. This feature is now disabled entirely, because not all code paths necessary for a successful realization were fully implemented.

Mitigating Controls (NIST 800-53 r5) AI

Directly enforces policy-based information flow rules that block transmission of sensitive data to unauthorized actors.

Protection of information at rest requires encryption or equivalent safeguards for stored credentials.

Transmission confidentiality and integrity enforcement stops credentials from being sent in plaintext or without protection.

Enforces authorizations on logical access so that sensitive data is not released to unauthorized recipients.

Requires validation of outbound information to ensure sensitive content is not disclosed in responses or messages.

Authenticator management requires secure generation, storage, and distribution of credentials, directly stopping insecure methods.

prevents

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.

prevents

Data-masking techniques can prevent sensitive values from appearing in transmitted payloads.

prevents

Protecting secret and private keys against disclosure and unauthorized use decreases the exposure of credentials that are stored or transmitted in recoverable form.

prevents

Forbidding clear-text transmission and display of passwords, plus the use of stronger alternatives to passwords, prevents credentials from being obtained or reused by attackers.

prevents

Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.

mitigates

Classification identifies sensitive data so it is not inadvertently transmitted.
