The attacker, even with low privileges (having Create Session, Create Procedure privilege), can exploit this vulnerability over a network using Oracle Net. Successful exploitation can allow the attacker to gain unauthorized access to critical data or achieve complete access to all data that the Java VM can access.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-634261650\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<pre><code class=\"\" data-line=\"\">\/\/ Connect to the Oracle Database Server\nOracleDataSource ods = new OracleDataSource();\nods.setURL(&quot;jdbc:oracle:thin:@target.oracle.server:1521:orcl&quot;);\nods.setUser(&quot;low_privileged_user&quot;);\nods.setPassword(&quot;password&quot;);\n\/\/ Create a session and a malicious procedure\nConnection conn = ods.getConnection();\nStatement stmt = conn.createStatement();\nstmt.execute(&quot;CREATE OR REPLACE PROCEDURE malicious_procedure AS BEGIN EXECUTE IMMEDIATE &#039;malicious_payload&#039;; END;&quot;);\nstmt.close();\nconn.close();<\/code><\/pre>\n<p>In the above conceptual example, a low privileged user creates a malicious procedure that carries out the attack.
