CVE-2004-0230

NVD-CWE-OtherPublished: August 18, 2004· Updated: Jun 16, 2026

5.0

CVSS v3.1

Official Description

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

Technical Analysis

CVE-2004-0230 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-2004-0230. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
