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

CVE-2025-30762 refers to a significant vulnerability found in the Oracle WebLogic Server product of Oracle Fusion Middleware. This vulnerability can be easily exploited by an unauthenticated attacker with network access via T3, IIOP. Successful exploitation could lead to unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data. This risk is particularly pertinent to organizations using affected versions of Oracle WebLogic Server, as it could result in system compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-30762
\nSeverity: High – CVSS 3.1 Base Score 7.5
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data<\/p>\n

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

Product | Affected Versions<\/p>\n

Oracle WebLogic Server | 12.2.1.4.0
\nOracle WebLogic Server | 14.1.1.0.0
\nOracle WebLogic Server | 14.1.2.0.0<\/p>\n

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

The vulnerability exists due to insufficient access restriction within Oracle WebLogic Server. An unauthenticated attacker can exploit this weakness by sending a specially crafted request over the T3 or IIOP protocol to the affected server. Upon successful exploitation, the attacker could gain unauthorized access to critical data or potentially all data accessible by the Oracle WebLogic Server.<\/p>\n

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

While exact methods may vary according to each attacker’s approach, the conceptual example below highlights a possible exploitation method:<\/p>\n

POST \/OracleWebLogic\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"exploit_code\": \"...\" }<\/code><\/pre>\n
In this example, the attacker sends a POST request with a malicious JSON payload to a vulnerable endpoint on the Oracle WebLogic Server, potentially gaining unauthorized access to critical data.<\/p>\n","protected":false},"excerpt":{"rendered":"
