What is CVE-2013-0340?
CVE-2013-0340 is a medium-severity vulnerability in Apple Ipados, published on 21 Jan 2014. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
expat before version 2.4.0 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.
Weakness: CWE-611
