About this tag
CVE-2013-5211 is a vulnerability in the Network Time Protocol (NTP) service that enables NTP amplification attacks, a form of Distributed Denial of Service (DDoS). The flaw allows an attacker to send a small "get monlist" request to a vulnerable NTP server, which then responds with a large amount of traffic directed at a victim, overwhelming their system. This issue affects publicly accessible NTP servers and has been exploited in critical infrastructure environments. Discussions on WindowsForum cover the technical details of the attack, mitigation steps, and related advisories from CISA and Hitachi Energy. Administrators are urged to update their NTP servers to prevent exploitation.
