Descriptions

Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS Core Components). Supported versions that are affected are 10.3.6.0.0, 12.1.3.0.0 and 12.2.1.3.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data as well as unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 5.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N).

Una vulnerabilidad en el componente Oracle WebLogic Server de Fusion Middleware de Oracle (subcomponente: WLS Core Components). Las versiones compatibles que están afectadas son 10.3.6.0.0, 12.1.3.0.0 y 12.2.1.3.0. La vulnerabilidad fácilmente explotable permite a un atacante muy privilegiado con acceso a la red por medio de HTTP comprometer a Oracle WebLogic Server. Los ataques con éxito de esta vulnerabilidad pueden resultar en acceso no autorizado a datos críticos o acceso completo a todos los datos accesibles de Oracle WebLogic Server, así como en actualizaciones no autorizadas, insertar o eliminar el acceso a algunos de los datos accesibles de Oracle WebLogic Server. CVSS 3.0 Puntuación Base 5.5 (Impactos de Confidencialidad e Integridad). Vector CVSS: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N).

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle WebLogic. Authentication is required to exploit this vulnerability.
The specific flaw exists within the DeploymentService, which listens on TCP port 7001 by default. When parsing the wl_request_type header, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of the current process.
