CVE-2010-0476
Status: ModifiedHigh (10)—💥 Exploit
The SMB client in Microsoft Windows Server 2003 SP2, Vista Gold, SP1, and SP2, and Windows Server 2008 Gold and SP2 allows remote SMB servers and man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and reboot) via a crafted SMB transaction response that uses (1) SMBv1 or (2) SMBv2, aka "SMB Client Response Parsing Vulnerability."
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
- Base score: 10
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 34%
- Percentile among all scored CVEs: 98
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
💥 Public exploits
Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
