The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the July 2020 CPU advisory.

  - Vulnerability in the MapViewer (Apache Commons     FileUpload) component of Oracle Database Server.
    Supported versions that are affected are 12.2.0.1, 18c     and 19c. Easily exploitable vulnerability allows low     privileged attacker having Valid User Account privilege     with network access via HTTP to compromise MapViewer     (Apache Commons FileUpload). Successful attacks of this     vulnerability can result in takeover of MapViewer     (Apache Commons FileUpload). Note: MapViewer is not     deployed with a default installation. To use MapViewer     the customer needs to re-deploy MapViewer EAR file into     Oracle WebLogic Server. CVSS 3.1 Base Score 8.8     (Confidentiality, Integrity and Availability impacts).
    (CVE-2016-1000031)

  - Vulnerability in the Java VM component of Oracle     Database Server. Supported versions that are affected     are 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c and 19c. Difficult     to exploit vulnerability allows low privileged attacker     having Create Session, Create Procedure privilege with     network access via multiple protocols to compromise Java     VM. Successful attacks require human interaction from a     person other than the attacker and while the     vulnerability is in Java VM, attacks may significantly     impact additional products. Successful attacks of this     vulnerability can result in takeover of Java VM. CVSS     3.1 Base Score 8.0 (Confidentiality, Integrity and     Availability impacts). (CVE-2020-2968)

  - Vulnerability in the Core RDBMS (zlib) component of     Oracle Database Server. The supported version that is     affected is 18c. Easily exploitable vulnerability allows     high privileged attacker having Create Session privilege     with network access via Oracle Net to compromise Core     RDBMS (zlib). Successful attacks of this vulnerability     can result in takeover of Core RDBMS (zlib). CVSS 3.1     Base Score 7.2 (Confidentiality, Integrity and     Availability impacts).(CVE-2016-9843)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-201909-01 (Perl: Multiple vulnerabilities)

Multiple vulnerabilities were discovered in the implementation of the Perl programming language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2018-18311     Jayakrishna Menon and Christophe Hauser discovered an     integer overflow vulnerability in Perl_my_setenv leading     to a heap-based buffer overflow with attacker-controlled     input.

  - CVE-2018-18312     Eiichi Tsukata discovered that a crafted regular     expression could cause a heap-based buffer overflow     write during compilation, potentially allowing arbitrary     code execution.

  - CVE-2018-18313     Eiichi Tsukata discovered that a crafted regular     expression could cause a heap-based buffer overflow read     during compilation which leads to information leak.

  - CVE-2018-18314     Jakub Wilk discovered that a specially crafted regular     expression could lead to a heap-based buffer overflow.
