DNS poisoning via Port Exhaustion
Text to Speech
Watchfire released 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.
