CVE-2008-4114

Status: ModifiedHigh (7.1)—💥 Exploit

srv.sys in the Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via an SMB WRITE_ANDX packet with an offset that is inconsistent with the packet size, related to "insufficiently validating the buffer size," as demonstrated by a request to the \PIPE\lsarpc named pipe, aka "SMB Validation Denial of Service Vulnerability."

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
Base score: 7.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 49%
Percentile among all scored CVEs: 99
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.
