PHP SOAP parser can expose any file to attackers

CVE-2013-1643 · published 13 years ago
Summary

Versions of PHP prior to 5.3.23 and 5.4.13 allow a specially crafted SOAP description file to trick the parser into revealing any file on the server. This happens because the parser incorrectly processes external entity references in XML. Upgrade PHP to the fixed versions or apply a patch that disables external entity processing.

What to do

The CVE record does not list a fixed version. Check the vendor's site or the advisory links below - a fix may already be released.

The SOAP parser in PHP before 5.3.23 and 5.4.x before 5.4.13 allows remote attackers to read arbitrary files via a SOAP WSDL file containing an XML external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue in the soap_xmlParseFile and soap_xmlParseMemory functions. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-1824.
