Microsoft Internet Explorer 8/9 information disclosure

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

The second and final day of Pwn2Own 2014 saw successful attempts by seven entrants against five products, with $450,000 paid to researchers. This brings the two-day payout total to $850,000, not including charitable donations or the value of the laptops, ZDI points, and other prizes given to winning researchers.

The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details are unknown but an exploit is available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 04/07/2017). It is expected to see the exploit prices for this product decreasing in the near future.The attack technique deployed by this issue is T1592 according to MITRE ATT&CK.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2200 days. During that time the estimated underground price was around $25k-$100k.
