7.8

High

Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions: l2tpns versions prior to 2.1.21

Description: The issue is related to a buffer overflow in the cluster process heartbeat function, which can be exploited by remote attackers to cause a denial of service via a large heartbeat packet. Multiple vulnerabilities in the l2tpns package may lead to disruption of protected information availability, and exploitation can be done remotely.

Recommendations: For versions prior to 2.1.21, update to version 2.1.21 or later to resolve the issue. As a temporary workaround, consider restricting access to the cluster process heartbeat function in the l2tpns package to minimize the risk of exploitation.
