Vulnerability of Apache Batik: external XML entity injection

Synthesis of the vulnerability

An attacker can transmit malicious XML data to Apache Batik, in order to read a file, scan sites, or trigger a denial of service.
Severity of this announce: 2/4.
Creation date: 02/05/2017.
Références of this computer vulnerability: cpuapr2018, cpujul2018, cpuoct2017, CVE-2017-5662, DLA-926-1, DSA-4215-1, FEDORA-2017-43b46cd2da, FEDORA-2017-aff3dd3101, RHSA-2017:2546-01, RHSA-2017:2547-01, RHSA-2018:0319-01, USN-3280-1, VIGILANCE-VUL-22591.

Description of the vulnerability

XML data can contain external entities (DTD):
  <!ENTITY name SYSTEM "file">
  <!ENTITY name SYSTEM "http://server/file">
A program which reads these XML data can replace these entities by data coming from the indicated file. When the program uses XML data coming from an untrusted source, this behavior leads to:
 - content disclosure from files of the server
 - private web site scan
 - a denial of service by opening a blocking file
This feature must be disabled to process XML data coming from an untrusted source.

However, the Apache Batik parser allows external entities.

An attacker can therefore transmit malicious XML data to Apache Batik, in order to read a file, scan sites, or trigger a denial of service.
