Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled log4net configuration files.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net     configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled     log4net configuration files. (CVE-2018-1285)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Apache log4net versions before 2.0.10 do not disable XML external entities when parsing log4net
    configuration files. This allows for XXE-based attacks in applications that accept attacker-controlled
    log4net configuration files. (CVE-2018-1285)

The version of Oracle Application Testing Suite installed on the remote host is affected by a vulnerability as referenced in the April 2022 CPU advisory.

  - Vulnerability in the Oracle Application Testing Suite product of Oracle Enterprise Manager (component:
    Load Testing for Web Apps (Apache log4net)). The supported version that is affected is 13.3.0.1. Easily     exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise     Oracle Application Testing Suite. Successful attacks of this vulnerability can result in takeover of     Oracle Application Testing Suite. (CVE-2018-1285)

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

According to its version, the Foxit PhantomPDF application (formally known as Phantom) installed on the remote Windows host is prior to 10.1.7. It is, therefore affected by multiple vulnerabilities:

  - Acrobat Reader DC version 21.007.20099 (and earlier), 20.004.30017 (and earlier) and 17.011.30204 (and     earlier) are affected by a heap overflow vulnerability due to insecure handling of a crafted file,     potentially resulting in arbitrary code execution in the context of the current user. Exploitation of this     issue requires user interaction in that a victim must open a malicious file. (CVE-2021-44708,     CVE-2021-44709)

  - Acrobat Reader DC version 21.007.20099 (and earlier), 20.004.30017 (and earlier) and 17.011.30204 (and     earlier) are affected by a Null pointer dereference vulnerability when parsing a specially crafted file.
    An unauthenticated attacker could leverage this vulnerability to achieve an application denial-of-service     in the context of the current user. Exploitation of this issue requires user interaction in that a victim     must open a malicious file. (CVE-2021-44740, CVE-2021-44741)

  - Foxit PDF Reader before 11.2.1 and Foxit PDF Editor before 11.2.1 have an Uncontrolled Search Path Element     for DLL files. (CVE-2022-24955)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit     PDF Reader 11.1.0.52543. User interaction is required to exploit this vulnerability in that the target     must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Doc     objects. By performing actions in JavaScript, an attacker can trigger a read past the end of an allocated     buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
    Was ZDI-CAN-15703. (CVE-2022-24358)

  - This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit     PDF Reader 11.1.0.52543. User interaction is required to exploit this vulnerability in that the target     must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Doc     objects. The issue results from the lack of validating the existence of an object prior to performing     operations on the object. An attacker can leverage this vulnerability to execute code in the context of     the current process. Was ZDI-CAN-15702. (CVE-2022-24359)

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