Hey,
Today we are releasing a very interesting whitepaper which describes a DNS
poisoning attack against stub resolvers.
It discloses two vulnerabilities:
A vulnerability in Java (CVE-2011-3552, CVE-2010-4448) which enables remote
DNS poisoning using Java applets. This vulnerability can be triggered when
opening a malicious webpage. A successful exploitation of this vulnerability
may lead to disclosure and manipulation of cookies and web pages, disclosure
of NTLM credentials and clipboard data of the logged-on user, and even
firewall bypass.
A vulnerability in multiuser Windows environments which enables local DNS
cache poisoning of arbitrary domains. This vulnerability can be triggered
by a normal user (i.e. one with non-administrative rights) in order to
attack other users of the system. A successful exploitation of this
vulnerability may lead to information disclosure, privilege escalation,
universal XSS and more.
