Target Milestone: ---
Classification: Other
An issue is present in Apache ZooKeeper 1.0.0 to 3.4.13 and 3.5.0-alpha to
3.5.4-beta. ZooKeeper's getACL() command doesn't check any permission when
retrieves the ACLs of the requested node and returns all information contained
in the ACL Id field as plaintext string. DigestAuthenticationProvider overloads
the Id field with the hash value that is used for user authentication. As a
consequence, if Digest Authentication is in use, the unsalted hash value will
be disclosed by getACL() request for unauthenticated or unprivileged users.
