Description

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 10 Update 2, 8 Update 181, 7 Update 191, or 6 Update 201. It is, therefore, affected by multiple vulnerabilities related to the following components :

  • Concurrency. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE (CVE-2018-2952)

  • Deployment. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE (CVE-2018-2964)

  • JSSE. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE (CVE-2018-2973)

  • Java DB. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE. (CVE-2018-2938)

  • JavaFX. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE. (CVE-2018-2941)

  • Libraries. An easily exploitable vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE. (CVE-2018-2940)

  • Security. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE (CVE-2018-2972)

  • Windows DLL. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise Java SE (CVE-2018-2942)

Note that Nessus has not tested for these issues but has instead relied only on the application
