Vulnerabilities (CVE)

DataHub is an open-source metadata platform. Prior to version 1.3.1.8, the LDAP ingestion source is vulnerable to MITM attack through TLS downgrade. This issue has been patched in version 1.3.1.8.

DataHub is an open-source metadata platform. When not using authentication for the metadata service, which is the default configuration, the Metadata service (GMS) will use the X-DataHub-Actor HTTP header to infer the user the frontend is sending the request on behalf of. When the backends retrieves the header, its name is retrieved in a case-insensitive way. This case differential can be abused by an attacker to smuggle an X-DataHub-Actor header with different casing (eg: X-DATAHUB-ACTOR). Thi ... DataHub is an open-source metadata platform.

When the backends retrieves the header, its name is retrieved in a case-insensitive way. This case differential can be abused by an attacker to smuggle an X-DataHub-Actor header with different casing (eg: X-DATAHUB-ACTOR). This issue may lead to an authorization bypass by allowing any user to impersonate the system user account and perform any actions on its behalf. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-079.

DataHub is an open-source metadata platform. The AuthServiceClient which is responsible for creation of new accounts, verifying credentials, resetting them or requesting access tokens, crafts multiple JSON strings using format strings with user-controlled data. This means that an attacker may be able to augment these JSON strings to be sent to the backend and that can potentially be abused by including new or colliding values.

This means that an attacker may be able to augment these JSON strings to be sent to the backend and that can potentially be abused by including new or colliding values. This issue may lead to an authentication bypass and the creation of system accounts, which effectively can lead to full system compromise. Users are advised to upgrade. There are no known workarounds for this vulnerability. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-080.

DataHub is an open-source metadata platform. In versions of DataHub prior to 0.8.45 Session cookies are only cleared on new sign-in events and not on logout events. Any authentication checks using the `AuthUtils.hasValidSessionCookie()` method could be bypassed by using a cookie from a logged out session, as a result any logged out session cookie may be accepted as valid and therefore lead to an authentication bypass to the system.

DataHub is an open-source metadata platform. The DataHub frontend acts as a proxy able to forward any REST or GraphQL requests to the backend. The goal of this proxy is to perform authentication if needed and forward HTTP requests to the DataHub Metadata Store (GMS). It has been discovered that the proxy does not adequately construct the URL when forwarding data to GMS, allowing external users to reroute requests from the DataHub Frontend to any arbitrary hosts.

It has been discovered that the proxy does not adequately construct the URL when forwarding data to GMS, allowing external users to reroute requests from the DataHub Frontend to any arbitrary hosts. As a result attackers may be able to reroute a request from originating from the frontend proxy to any other server and return the result. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-076.

DataHub is an open-source metadata platform. Prior to version 0.8.45, the `StatelessTokenService` of the DataHub metadata service (GMS) does not verify the signature of JWT tokens. This allows an attacker to connect to DataHub instances as any user if Metadata Service authentication is enabled.

This allows an attacker to connect to DataHub instances as any user if Metadata Service authentication is enabled. This vulnerability occurs because the `StatelessTokenService` of the Metadata service uses the `parse` method of `io.jsonwebtoken.JwtParser`, which does not perform a verification of the cryptographic token signature. This means that JWTs are accepted regardless of the used algorithm. This issue may lead to an authentication bypass. Version 0.8.45 contains a patch for the issue. There are no known workarounds.

Starting in version 0.1.143 and prior to version 0.2.182, due to configuration issues in the helm chart, if there was a successful initial deployment during a limited window of time, personal access tokens were possibly created with a default secret key. Since the secret key is a static, publicly available value, someone could inspect the algorithm used to generate personal access tokens and generate their own for an instance. Deploying with Metadata Service Authentication enabled would have been difficult during window of releases. If someone circumvented the helm settings and manually set Metadata Service Authentication to be enabled using environment variables directly, this would skip over the autogeneration logic for the Kubernetes Secrets and DataHub GMS would default to the signing key specified statically in the application.yml. Most deployments probably did not attempt to circumvent the helm settings to enable Metadata Service Authentication during this time, so impact is most likely limited. Any deployments with Metadata Service Authentication enabled should ensure that their secret values are properly randomized. Version 0.2.182 contains a patch for this issue. As a workaround, one may reset the token signing key to be a random value, which will invalidate active personal access tokens.
