Oracle TNS Listener Remote Poisoning

high Nessus Plugin ID 69552
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.
