Microsoft Windows up to XP SP3 SMB input validation

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 classified as very critical has been found in Microsoft Windows (Operating System). This affects an unknown code block of the component SMB. The manipulation with an unknown input leads to a input validation vulnerability (EternalBlue/EternalChampion/EternalRomance/EternalSynergy/NotPetya/WannaCry). CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The SMBv1 server in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607; and Windows Server 2016 allows remote attackers to execute arbitrary code via crafted packets, aka "Windows SMB Remote Code Execution Vulnerability." This vulnerability is different from those described in CVE-2017-0143, CVE-2017-0145, CVE-2017-0146, and CVE-2017-0148.

The bug was discovered 03/14/2017. The weakness was shared 03/14/2017 as MS17-010 as confirmed bulletin (Technet). It is possible to read the advisory at technet.microsoft.com. This vulnerability is uniquely identified as CVE-2017-0144 since 09/09/2016. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/26/2024).

A public exploit has been developed by Sean Dillon in Python and been published 2 months after the advisory. The exploit is shared for download at exploit-db.com. It is declared as attacked. We expect the 0-day to have been worth approximately $25k-$100k. A worm is spreading, which is automatically exploiting this vulnerability. The vulnerability scanner Nessus provides a plugin with the ID 97833 (MS17-010: Security Update for Microsoft Windows SMB Server (4013389) (ETERNALBLUE) (ETERNALCHAMPION) (ETERNALROMANCE) (ETERNALSYNERGY) (WannaCry) (EternalRocks) (Petya) (uncredentialed check)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 91345 (Microsoft SMB Server Remote Code Execution Vulnerability (MS17-010) and Shadow Brokers). The CISA Known Exploited Vulnerabilities Catalog lists this issue since 02/10/2022 with a due date of 08/10/2022:

Apply updates per vendor instructions.

Applying the patch MS17-010 is able to eliminate this problem. The bugfix is ready for download at technet.microsoft.com. A possible mitigation has been published immediately after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 41978.
