  - An unspecified vulnerability allows a remote unauthenticated 
    attacker with network access to compromise and takeover the 
    StorageTek Tape Analytics SW Tool. (CVE-2019-2725) (CVE-2019-2729)

  - An unspecified vulnerability allows a remote unauthenticated 
    attacker with network access to compromise and takeover the 
    Tape Virtual Storage Manager GUI. (CVE-2019-2725)

  - An unspecified vulnerability in the WLS Core Component allows an 
    authenticated low privileged attacker with network 
    access via HTTP to compromise Oracle WebLogic Server, resulting 
    in unauthorized update, insert or delete access to Oracle 
    WebLogic Server accessible data. (CVE-2019-2824) (CVE-2019-2827)

  - An unspecified vulnerability in the jQuery Component allows an 
    authenticated low privileged attacker with network 
    access via HTTP to compromise Oracle WebLogic Server, resulting 
    in unauthorized update, insert or delete access to Oracle 
    WebLogic Server accessible data. Successful attacks require
    human interaction from actions from another Weblogic user.
    (CVE-2016-71030)

  - An unspecified vulnerability in the Application Container - JavaEE
    Component of Oracle WebLogic Server allows an unauthenticated
    attacker with network access via T3 to compromise Oracle WebLogic
    Server. A successful attack of this vulnerability could result in
    takeover of Oracle WebLogic Server. (CVE-2019-2856)
    
  - An unspecified vulnerability in the Sample apps (Spring Framework)
    Component of Oracle WebLogic Server allows an unauthenticated
    attacker with network access via HTTP to compromise Oracle WebLogic
    Server. A successful attack of this vulnerability could result in
    unauthorized ability to cause a hang or frequently repeatable crash
    (complete DOS) of Oracle WebLogic Server. (CVE-2018-15756)");
