CWE-20Published: August 11, 2010· Updated: Jun 16, 2026
Official Description
The 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 Analysis
CVE-2010-2550 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2010-2550. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
