Descriptions

Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: SAML). Supported versions that are affected are 10.3.6.0, 12.1.3.0, 12.2.1.2 and 12.2.1.3. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data as well as unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N).

Vulnerabilidad en el componente Oracle WebLogic Server de Oracle Fusion Middleware (subcomponente: SAML). Las versiones compatibles que se han visto afectadas son la 10.3.6.0, 12.1.3.0, 12.2.1.2 y la 12.2.1.3. Esta vulnerabilidad fácilmente explotable permite que un atacante con pocos privilegios con acceso en red via HTTP comprometa la seguridad de Oracle WebLogic Server. Los ataques exitosos a esta vulnerabilidad pueden resultar en el acceso no autorizado a la actualización, inserción o supresión de algunos de los datos accesibles de Oracle WebLogic Server, así como el acceso de lectura sin autorización a un subconjunto de datos accesibles de Oracle WebLogic Server. CVSS 3.0 Base Score 5.4 (impactos de confidencialidad e integridad). Vector CVSS: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N).

Two vulnerabilities were discovered within the Oracle WebLogic SAML service provider authentication mechanism. By inserting an XML comment into the SAML NameID tag, an attacker can coerce the SAML service provider to log in as another user. Additionally, WebLogic does not require signed SAML assertions in the default configuration. By omitting the signature portions from a SAML assertion, an attacker can craft an arbitrary SAML assertion and bypass the authentication mechanism.
