CVE-2013-0340 (GCVE-0-2013-0340)

Vulnerability from cvelistv5 – Published: 2014-01-21 18:00 – Updated: 2025-11-25 16:27
VLAI?
Summary
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.
Severity ?
No CVSS data available.
