Overview<\/strong><\/p>\n

The vulnerability CVE-2025-50069 is a serious threat that affects the Java Virtual Machine (JVM) component of the Oracle Database Server. This vulnerability exposes certain versions of the Oracle Database Server to potential system compromise or data leakage by low privileged attackers. The severity and widespread use of the affected software make this vulnerability a significant concern for businesses and organizations alike.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-50069
\nSeverity: Critical (CVSS 3.1 Base Score 7.7)
\nAttack Vector: Network (Oracle Net)
\nPrivileges Required: Low (Create Session, Create Procedure)
\nUser Interaction: None
\nImpact: Unauthorized access to critical data or complete access to all Java VM accessible data<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Oracle Database Server (Java VM Component) | 19.3 to 19.27, 21.3 to 21.18<\/p>\n

How the Exploit Works<\/strong><\/p>\n

An attacker exploiting this vulnerability would leverage a flaw in the Java VM component of the Oracle Database Server. 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

Conceptual Example Code<\/strong><\/p>\n

\/\/ Connect to the Oracle Database Server\nOracleDataSource ods = new OracleDataSource();\nods.setURL(\"jdbc:oracle:thin:@target.oracle.server:1521:orcl\");\nods.setUser(\"low_privileged_user\");\nods.setPassword(\"password\");\n\/\/ Create a session and a malicious procedure\nConnection conn = ods.getConnection();\nStatement stmt = conn.createStatement();\nstmt.execute(\"CREATE OR REPLACE PROCEDURE malicious_procedure AS BEGIN EXECUTE IMMEDIATE 'malicious_payload'; END;\");\nstmt.close();\nconn.close();<\/code><\/pre>\n
In the above conceptual example, a low privileged user creates a malicious procedure that carries out the attack. The malicious payload would be specifically crafted to exploit the vulnerability in the Java VM, leading to unauthorized data access.<\/p>\n","protected":false},"excerpt":{"rendered":"
