Title

NTP ntpd代码注入漏洞

Description

ntpd（Network Time Protocol daemon）是一个操作系统守护进程，它使用网络时间协议（NTP）与时间服务器的系统时间保持同步。基于Linux和OS X平台的NTP 4.2.8p1之前4.x版本的ntpd中的ntp_io.c文件中的‘read_network_packet’函数存在安全漏洞。由于程序未能正确确定源IP地址是否是IPv6回送地址。远程攻击者可通过从::1地址向ntpd机器的网络接口发送数据包，利用该漏洞伪造受限制数据包，读取或写入runtime状态。

CVE-2014-9751 (GCVE-0-2014-9751)

Vulnerability from cvelistv5 – Published: 2015-10-04 20:00 – Updated: 2024-08-06 13:55

Summary

The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address.

Severity

No CVSS data available.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
