Official Description
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."
Technical Analysis
CVE-2009-2532 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-2009-2532. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
