CWE-399Published: April 14, 2010· Updated: Jun 16, 2026
Official Description
The SMB client in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly allocate memory for SMB responses, which allows remote SMB servers and man-in-the-middle attackers to execute arbitrary code via a crafted (1) SMBv1 or (2) SMBv2 response, aka "SMB Client Memory Allocation Vulnerability."
Technical Analysis
CVE-2010-0269 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-2010-0269. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
