    Oracle Fusion Middleware 10.3.6.0.0<\/p>\n\n\n\n

    Oracle Fusion Middleware 12.1.3.0<\/p>\n\n\n\n

    Vulnerability description:<\/p>\n\n\n\n

    Oracle Fusion Middleware is a business creativity platform for enterprises and cloud environments. A vulnerability in Oracle WebLogic Server Application Container – JavaEE component allows unauthenticated attackers to remotely execute commands via the T3 protocol, which is enabled by default to take over Oracle WebLogic Server, thus affecting the confidentiality, integrity, and availability of the component. The vulnerability can be triggered under the default configuration of Oracle WebLogic Server, with no need for administrator authentication and additional interaction.<\/p>\n\n\n\n

    • Google Chrome V8 type confusion vulnerability<\/li><\/ul>\n\n\n\n

      CVE-2020-6814<\/p>\n\n\n\n

      NSFOCUS ID: 45988<\/p>\n\n\n\n

      Affected versions:<\/p>\n\n\n\n

      Google Chrome < 80.0.3987.122<\/p>\n\n\n\n

      Vulnerability description:<\/p>\n\n\n\n

      V8 is an open-source JavaScript and WebAssembly engine of Google and is used in Chrome. A type confusion vulnerability in V8 implementation in Google Chrome < 80.0.3987.122 might allow attackers to gain unauthorized access to data, thereby incurring the risk of malicious code execution.<\/p>\n\n\n\n

      • Apache Kylin remote command execution vulnerability<\/li><\/ul>\n\n\n\n

        CVE-2020-1956<\/p>\n\n\n\n

        NSFOCUS ID: 46860<\/p>\n\n\n\n

        Affected versions:<\/p>\n\n\n\n

        Apache Group Kylin 2.3.0 – 2.3.2<\/p>\n\n\n\n

        Apache Group Kylin 2.4.0 – 2.4.1<\/p>\n\n\n\n

        Apache Group Kylin 2.5.0 – 2.5.2<\/p>\n\n\n\n

        Apache Group Kylin 2.6.0 – 2.6.5<\/p>\n\n\n\n

        Apache Group Kylin 3.0.0 – 3.0.1<\/p>\n\n\n\n

        Apache Group Kylin 3.0.0-alpha<\/p>\n\n\n\n

        Apache Group Kylin 3.0.0-alpha2<\/p>\n\n\n\n

        Apache Group Kylin 3.0.0-beta<\/p>\n\n\n\n

        Vulnerability description:<\/p>\n\n\n\n

        Apache Kylin is an open-source distributed analytical data warehouse from Apache Software Foundation (ASF). It is designed to provide online analytical processing (OLAP) capability of SQL interface and multidimensional analysis on Hadoop\/Spark to support extremely large datasets. Apache Kylin has some RESTful APIs that will associate OS commands with user-typed strings. As Apache Kylin fails to properly verify user input, an attacker could execute arbitrary system commands without authorization.<\/p>\n\n\n\n

        • IBM WebSphere Application Server remote code execution vulnerability<\/li><\/ul>\n\n\n\n

          CVE-2020-4450<\/p>\n\n\n\n

          NSFOCUS ID: 46867<\/p>\n\n\n\n

          Affected versions<\/p>\n\n\n\n

          IBM Websphere Application Server 8.5.x<\/p>\n\n\n\n

          IBM Websphere Application Server 9.0.x<\/p>\n\n\n\n

          Vulnerability description:<\/p>\n\n\n\n

          WebSphere Application Server (WAS) 9.0.x and 8.5.x are prone to a deserialization vulnerability in the handling of the Internet Inter-ORB Protocol (IIOP). By exploiting this vulnerability, an unauthenticated attacker could remotely target the WAS server via IIOP to execute arbitrary code on the target server and gain system privileges, thereby taking control of the server. As WAS enables IIOP by default, attackers could launch remote attacks without authentication. Therefore, this high-risk vulnerability has an extensive impact.<\/p>\n\n\n\n

          • Apache Dubbo Provider default deserialization remote code execution vulnerability<\/li><\/ul>\n\n\n\n

            CVE-2020-1948<\/p>\n\n\n\n

            NSFOCUS ID: 46973<\/p>\n\n\n\n

            Affected versions<\/p>\n\n\n\n

            Apache Dubbo 2.6.0 <= Dubbo Version <= 2.6.<\/p>\n\n\n\n

            Apache Dubbo 2.7.0 <= Dubbo Version <= 2.7.<\/p>\n\n\n\n

            Apache Dubbo Dubbo <= 2.5.0<\/p>\n\n\n\n

            Unaffected versions<\/p>\n\n\n\n

            Apache Dubbo Dubbo >= 2.7.7<\/p>\n\n\n\n

            Vulnerability description:<\/p>\n\n\n\n

            On June 23, 2020, Apache Dubbo released a security bulletin to disclose the remote code execution vulnerability (CVE-2020-1948) caused by the default deserialization of the Provider. An attacker could send RPC requests with a payload of an unrecognized service name or method name and certain malicious parameters. Deserialization of malicious parameters will cause code execution.<\/p>\n\n\n\n
