AI-analyzed exploit summary This PoC demonstrates NTP DDoS amplification (CVE-2013-5211) by crafting a spoofed UDP packet with a MON_GETLIST request to an NTP server, which can be abused to reflect traffic to a target. The code constructs raw IP/UDP/NTP packets and sends a single packet for educational purposes.
Description
The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013.
