CVE-2007-1531

Status: ModifiedMedium (5)—💥 Exploit

Microsoft Windows XP and Vista overwrites ARP table entries included in gratuitous ARP, which allows remote attackers to cause a denial of service (loss of network access) by sending a gratuitous ARP for the address of the Vista host.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Base score: 5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 23%
Percentile among all scored CVEs: 98
Score date: 10/8/2026

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.
