In Apache FOP before 2.2, files lying on the filesystem of the server which uses FOP can be revealed to arbitrary users who send maliciously formed SVG files. The file types that can be shown depend on the user context in which the exploitable application is running. If the user is root a full compromise of the server - including confidential or sensitive files - would be possible. XXE can also be used to attack the availability of the server via denial of service as the references within a xml document can trivially trigger an amplification attack.

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

  - In Apache FOP before 2.2, files lying on the filesystem of the server which uses FOP can be revealed to     arbitrary users who send maliciously formed SVG files. The file types that can be shown depend on the user     context in which the exploitable application is running.

XXE can also be used to attack the     availability of the server via denial of service as the references within a xml document can trivially     trigger an amplification attack. (CVE-2017-5661)

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

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is less than 5.19.0 and is therefore affected by multiple vulnerabilities in the following components: 
  - Apache FOP
  - Underscore
  - Handlebars
  - PHP
  - sqlite

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

It was discovered that an XML external entities vulnerability in the Apache FOP XML formatter may result in information disclosure.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3281-1 advisory.

    Pierre Ernst discovered that Apache Fop incorrectly handled XML external entities. A remote attacker could     possibly use this issue to obtain sensitive files from the filesystem, or cause a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

For Debian 7 'Wheezy', these problems have been fixed in version 1:1.0.dfsg2-6+deb7u1.

We recommend that you upgrade your fop packages.
