Description

This module exploits CVE-2018-2392 and CVE-2018-2393, two XXE vulnerabilities within the XMLCHART page
of SAP Internet Graphics Servers (IGS) running versions 7.20, 7.20EXT, 7.45, 7.49, or 7.53. These
vulnerabilities occur due to a lack of appropriate validation on the Extension HTML tag when
submitting a POST request to the XMLCHART page to generate a new chart.

Successful exploitation will allow unauthenticated remote attackers to read files from the server as the user
from which the IGS service is started, which will typically be the SAP admin user. Alternatively attackers
can also abuse the XXE vulnerability to conduct a denial of service attack against the vulnerable
SAP IGS server.
