Oracle TNS Listener Remote Poisoning

high Nessus Plugin ID 69552


It was possible to register with a remote Oracle TNS listener.


The remote Oracle TNS listener allows service registration from a remote host. An attacker can exploit this issue to divert data from a legitimate database server or client to an attacker-specified system.

Successful exploits will allow the attacker to manipulate database instances, potentially facilitating man-in-the-middle, session- hijacking, or denial of service attacks on a legitimate database server.


Apply the workaround in Oracle's advisory.
