CVE-2010-2550
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe SMB Server in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate fields in an SMB request, which allows remote attackers to execute arbitrary code via a crafted SMB packet, aka "SMB Pool Overflow Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe SMB Server in multiple Windows versions (XP SP2/SP3, Server 2003 SP2, Vista SP1/SP2, Server 2008 Gold/SP2/R2, Windows 7) fails to properly validate fields in SMB requests, enabling remote attackers to execute arbitrary code via a crafted SMB packet through a pool overflow vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Windows versionRun 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to retrieve the installed Windows versionAffected if The version is Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, or Windows 7 (all versions of these products)
-
Verify SMB Server service is runningRun 'services.msc' and locate 'Server' service (SMB 1.0) or run 'sc query' and 'netstat -an | findstr "445\|139"' to check if SMB ports are listeningAffected if The SMB Server service is running and listening on TCP ports 445 or 139, making the service exposed to network requests
-
Confirm SMB is bound to network interfacesRun 'netstat -ano | findstr ":445"' or check adapter bindings in network connection properties for Server serviceAffected if SMB is bound to accessible network adapters, indicating the system can receive remote SMB requests
-
Determine patch levelRun 'wmic qfe list' or check Windows Update history for installed security updates related to MS10-054 (the patch for this CVE)Affected if The system lacks the security update MS10-054 or subsequent SMB security patches, and the version matches the affected product list
The system is affected if it runs an unpatched Windows XP, Server 2003, Vista, Server 2008, or Windows 7 version with the SMB Server service enabled and accessible on the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply Microsoft security patches for this vulnerability; as a defensive measure, block SMB ports (445/139) at network perimeter or disable SMB if not required.
N/A - this is a patch for existing systems; for long-term security, upgrade to a supported Windows version (Windows 10/11 or Windows Server 2016+)
- Apply Microsoft Security Update MS10-054, which addresses this vulnerability
- Deploy the update through your organization's patch management system or manually via Windows Update
- After patching, verify the SMB service is running correctly and test SMB functionality
