Detailsinfo

A vulnerability has been found in Microsoft Windows (Operating System) (version unknown) and classified as very critical. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a code injection vulnerability (EducatedScholar). The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Microsoft Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold and SP2, and Windows 7 RC do not properly process the command value in an SMB Multi-Protocol Negotiate Request packet, which allows remote attackers to execute arbitrary code via a crafted SMBv2 packet to the Server service, aka "SMBv2 Command Value Vulnerability."

The weakness was shared 10/14/2009 (Website). The advisory is shared at us-cert.gov. This vulnerability is known as CVE-2009-2532. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 11/13/2025). MITRE ATT&CK project uses the attack technique T1059 for this issue.

It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 42106 , which helps to determine the existence of the flaw in a target environment. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90527 (Microsoft Server Message Block (SMBv2) Remote Code Execution Vulnerability (MS09-050) and Shadow Brokers (EDUCATEDSCHOLAR)).

Upgrading eliminates this vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8649.

The vulnerability is also documented in the databases at Tenable (42106), SecurityFocus (BID 36594†) and Vulnerability Center (SBV-23728†). The entries VDB-4031, VDB-50451, VDB-50448 and VDB-50447 are related to this item. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
