Microsoft Internet Explorer Sandbox privileges management

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.

As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was released 08/13/2013 with VUPEN as MS13-059 as confirmed advisory (Website) via ZDI (Zero Day Initiative). The advisory is shared for download at zerodayinitiative.com. The public release was coordinated with the vendor. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 04/07/2017). It is expected to see the exploit prices for this product decreasing in the near future.The MITRE ATT&CK project declares the attack technique as T1068. The advisory points out:

The specific flaw exists within the processing of data shared to the broker by the sandboxed process. The issue lies in the failure to validate objects after a sandboxed process has terminated.

The vulnerability was handled as a non-public zero-day exploit for at least 109 days. During that time the estimated underground price was around $25k-$100k.

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at OSVDB (96920†). Entries connected to this vulnerability are available at VDB-9930, VDB-9931, VDB-9932 and VDB-9933. Once again VulDB remains the best source for vulnerability data.
