CPU on Intel/AMD/ARM Speculative Execution Meltdown 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.

Detailsinfo

A vulnerability has been found in CPU on Intel/AMD/ARM (Chip Software) and classified as critical. Affected by this vulnerability is an unknown code of the component Speculative Execution. The manipulation with an unknown input leads to a information disclosure vulnerability (Meltdown). The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. The summary by CVE is:

Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.

The bug was discovered 01/03/2018. The weakness was published 01/03/2018 by Jann Horn, Werner Haas, Thomas Prescher, Daniel Gruss, Moritz Lipp, Stefan Mangard and Michael Schwarz as confirmed blog post (Website). The advisory is shared at googleprojectzero.blogspot.com. The public release has been coordinated with the project team. This vulnerability is known as CVE-2017-5754 since 02/01/2017. 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 a public exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

A public exploit has been developed in ANSI C and been published immediately after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 8403 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 106801 (KB4074596: Windows 10 February 2018 Security Update (Meltdown)(Spectre)), which helps to determine the existence of the flaw in a target environment.
