Description Tomas Hoger 2018-04-16 21:40:46 UTC

It was discovered that the RMI component of OpenJDK enabled HTTP transport for RMI servers by default.  This could possibly expose RMI services to attackers who can not connect to them directly by attacking web browsers of users able to directly connect to the services.

The fix for this issue disables the use of RMI HTTP transport by default.  System properly java.rmi.server.disableIncomingHttp (with the default value of "true") can be used to enable HTTP transport.

Comment 1 Tomas Hoger 2018-04-17 20:57:25 UTC

Public now via Oracle CPU April 2018:

http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html#AppendixJAVA

The issue was fixed in Oracle 8u171, 7u181, and 6u191.

Comment 2 Tomas Hoger 2018-04-17 20:59:22 UTC

Relevant entry in the Oracle JDK release notes:

  core-libs/java.rmi
  Server-side HTTP-tunneled RMI Connections Disabled

  Server side HTTP-tunneled RMI connections have been disabled by default
  in this release. This behavior can be reverted by setting the runtime
  property sun.rmi.server.disableIncomingHttp property to false. Note, this
  should not be confused with the sun.rmi.server.disableHttp property, which
  disables HTTP-tunneling on the client side and is false by default.

  JDK-8193833 (not public)
