Exploit Title: Blind XXE (XML External Entity)in SAP
Date of Disclosure: 17/05/2017
Author: Ravindra Singh Rathore
Vendor Homepage: https://www.sap.com/products/business-one.html
Product - SAP Business One Android Application
Version - 1.2.3
Security Note: 2378065
CVE - CVE-2016-6256
CVSS - 6.5
XXE - An XML External Entity(XXE) attack is a type of attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts.
SAP Business One Android Application is vulnerable to XXE. A remote attacker could exploit this vulnerability to expose highly sensitive information from servers.
