Title: NTP任意文件覆盖漏洞

Description:

NTP（Network Time Protocol，网络时间协议）是一种以数据包交换把两台电脑的时钟同步化的网络协议。

NTP 4.2.8p4之前版本和4.3.77之前4.3.x版本中存在安全漏洞。由于程序允许使用:config命令无限制地设置pidfile和driftfile路径。远程攻击者可借助ntpd进程的pid或系统时钟的drift利用该漏洞覆盖任意文件。

Summary

The "pidfile" or "driftfile" directives in NTP ntpd 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77, when ntpd is configured to allow remote configuration, allows remote attackers with an IP address that is allowed to send configuration requests, and with knowledge of the remote configuration password to write to arbitrary files via the :config command.
