CPU on Intel/AMD/ARM Speculative Execution Spectre 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 was found in CPU on Intel/AMD/ARM (Chip Software) and classified as critical. Affected by this issue is an unknown code block of the component Speculative Execution. The manipulation with an unknown input leads to a information disclosure vulnerability (Spectre). Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

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

The bug was discovered 01/03/2018. The weakness was released 01/03/2018 by Jann Horn, Paul Kocher, Daniel Genkin, Mike Hamburg, Moritz Lipp and Yuval Yarom with Google Project Zero as confirmed blog post (Website). The advisory is available at googleprojectzero.blogspot.com. The vendor was not involved in the coordination of the public release. This vulnerability is handled as CVE-2017-5753 since 02/01/2017. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/29/2026). This vulnerability is assigned to T1592 by the MITRE ATT&CK project. This vulnerability has a historic impact due to its background and reception.

A public exploit has been developed in Javascript and been published immediately after the advisory. The exploit is available at googleprojectzero.blogspot.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 106342 (SUSE SLED12 / SLES12 Security Update : wireshark (SUSE-SU-2018:0191-1) (Spectre)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 172018 (SUSE Enterprise Linux Security Update for the Linux Kernel (SUSE-SU-2019:0222-1)).

It is possible to mitigate the problem by applying the configuration setting . A possible mitigation has been published 3 weeks after the disclosure of the vulnerability. The blog post contains the following remark:

Since this exploit can be executed through the website, Chrome users can turn on Site Isolation feature on their devices to mitigate these flaws.

The vulnerability is also documented in the databases at Exploit-DB (43427), Tenable (106342), SecurityFocus (BID 102371†), SecurityTracker (ID 1040071†) and CERT Bund (WID-SEC-2022-0532). spectreattack.com is providing further details.
