CVE-2013-7331
KEVMicrosoft Internet Explorer Information Disclosure Vulnerability
Description
An information disclosure vulnerability exists in Internet Explorer which allows resources loaded into memory to be queried. This vulnerability could allow an attacker to detect anti-malware applications.
The Microsoft.XMLDOM ActiveX control in Microsoft Windows 8.1 and earlier allows remote attackers to determine the existence of local pathnames, UNC share pathnames, intranet hostnames, and intranet IP addresses by examining error codes, as demonstrated by a res:// URL, and exploited in the wild in February 2014.
