Apache Pulsar Manager is a web console for administering Apache Pulsar clusters. It has its own user accounts and login, and it can be configured with an HTTP authentication credential, such as a token, that it uses to call the Pulsar admin API on behalf of its users. Pulsar Manager has the following security issues: - The operation for creating the initial administrator (superuser) account is available without authentication, and it remains available after the instance has been initialized. Anyone who can reach Pulsar Manager can create an additional administrator account at any time and log in with it. This issue affects versions 0.3.0 and later. - Requests to the Pulsar admin API that Pulsar Manager proxies to the configured Pulsar cluster are not subject to Pulsar Manager's authentication. Version 0.2.0 checks the caller's permissions for some of these requests, but not for all of them. An unauthenticated user can therefore use Pulsar Manager to send requests to the Pulsar admin API, which the cluster processes with the credential configured in Pulsar Manager. - The destination of a proxied request can be chosen by the requester, and Pulsar Manager attaches its configured Pulsar admin credential to the request. An unauthenticated user can make Pulsar Manager send this credential to a host of the user's choosing, and the credential can then be used directly against the Pulsar cluster. - In versions 0.3.0 and later, Pulsar Manager does not distinguish between privilege levels of its accounts. Every account, including one created through the first issue, effectively has full administrative privileges in Pulsar Manager. The impact depends on the version and the deployment. In versions 0.3.0 and later, any user who can reach Pulsar Manager over the network can take full control of Pulsar Manager. In all versions, when Pulsar Manager is configured with an HTTP authentication credential for a Pulsar cluster, any user who can reach Pulsar Manager can perform the Pulsar
