CVE-2013-2192: Low severity apache hadoop vulnerability
It was reported [1] that:
"The Apache Hadoop RPC protocol is intended to provide bidirectional authentication between clients and servers. However, a malicious server or network attacker can unilaterally disable these authentication checks. This allows for potential reduction in the configured quality of protection of the RPC traffic, and privilege escalation if authentication credentials are passed over RPC."
This flaw only affects users who have enabled Hadoop's kerberos security features. This is corrected in upstream versions 0.23.9, 1.2.1, and 2.0.6-alpha.

Other sources
The RPC protocol implementation in Apache Hadoop 2.x before 2.0.6-alpha, 0.23.x before 0.23.9, and 1.x before 1.2.1, when the Kerberos security features are enabled, allows man-in-the-middle attackers to disable bidirectional authentication and obtain sensitive information by forcing a downgrade to simple authentication.
