Python Improper Restriction of XML External Entity Reference Vulnerability - CVE-2013-0340

Medium
Reference: CVE-2013-0340
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2013-0340
Title: Python Improper Restriction of XML External Entity Reference Vulnerability
Overview:

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function which allows remote attackers to cause a denial of service (resource consumption) send HTTP requests to intranet servers or read arbitrary files via a crafted XML document aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion the responsibility for resolving this issue lies with application developers according to this argument this entry should be REJECTed and each affected application would need its own CVE.
