             Summary: Add support for filtering input in TcpSocketServer and UdpSocketServer
                 Key: LOG4J2-1863
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1863
             Project: Log4j 2
          Issue Type: New Feature
          Components: Receivers
    Affects Versions: 2.8.1
            Reporter: Matt Sicker
            Assignee: Matt Sicker
             Fix For: 2.8.2


It is best practice to add a configurable class filter to ObjectInputStream usage when input comes from untrusted sources. Add this feature to TcpSocketServer and UdpSocketServer along with sensible default settings. This feature is unnecessary in JmsServer as that relies on the underlying configuration of the JMS server (e.g., ActiveMQ has a similar configuration option).
