Loading vulnerability…
CVE-2001-0414 is a buffer overflow vulnerability in the NTP daemon (ntpd), affecting NTP 4.0.99k and earlier, also referred to as xntpd/xntp3. The flaw is reported in the ctl_getitem() function within the daemon's control-message handling code (ntp_control.c). A remote attacker can trigger the issue by sending a crafted NTP control request containing an overly long readvar argument. Successful exploitation can crash the daemon and, according to the provided advisory context, may permit arbitrary code execution with the privileges of the ntpd process, which commonly runs as root.

This repository contains a single Metasploit exploit module targeting a stack-based buffer overflow vulnerability in the ntpd (Network Time Protocol Daemon) service, specifically versions found in RedHat Linux 7.0 (ntpd 4.0.99j and 4.0.99k). The exploit works by sending a specially crafted 'readvar' request over UDP port 123, causing a buffer overflow and enabling remote code execution as a privileged user. The module uses the egghunter technique to locate and execute the payload, which is customizable via Metasploit and avoids certain bad characters. The exploit is operational and can be used to gain a shell or execute arbitrary commands on vulnerable systems. The only file in the repository is a Ruby script structured as a standard Metasploit module, making use of Metasploit's UDP and egghunter mixins.
