TCP Sequence Number Approximation Reset Denial of Service Vulnerability

Published: 2012-03-01 09:45:15
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Summary:
The host is running TCP services and is prone to denial of service vulnerability.

Detection Method:
A TCP Reset packet with a different sequence number is sent to the target. A previously open connection is then checked to see if the target closed it or not.

Recommendations:
Please see the referenced advisories for more information on obtaining and applying fixes.

Technical Details:
The flaw is triggered when spoofed TCP Reset packets are received by the targeted TCP stack and will result in loss of availability for the attacked TCP services.

Affected Versions:
TCP/IP v4

Impact:
Successful exploitation will allow remote attackers to guess sequence numbers and cause a denial of service to persistent TCP connections by repeatedly injecting a TCP RST packet.

Detection Type:
Remote Banner Unreliable

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
