Pwn2Own (Pwn4Fun) HP Zero Day Initiative Privilege Escalation Technique Disclosed!

StephanieWisdom ‎07-30-2014 02:59 PM - edited ‎06-09-2015 10:37 AM

Today the HP Zero Day Initiative (ZDI) disclosed information on a privilege escalation technique in Microsoft Internet Explorer (ZDI-14-270). This technique was discovered earlier this year and demonstrated at the 2014 Pwn4Fun charity competition held by ZDI. HP TippingPoint Intrusion Prevention System (IPS) customers – as of 04/08/2014 – have exclusive coverage in the form of filter 13787, or 113 days prior to disclosure. This vulnerability may be chained with others to allow for privilege escalation to medium integrity in Microsoft Internet Explorer. The vulnerability is in the browser’s failure to maintain integrity checks on browser processes when proxied through localhost. 


See further details of the vulnerability here. Due to the nature of this vulnerability, Microsoft has stated they will not be providing a patch.
