CVE-2015-8140 [MEDIUM] CWE-294 ntp: ntpq protocol vulnerable to replay attacks
ntp: ntpq protocol vulnerable to replay attacks
The ntpq protocol in NTP before 4.2.8p7 allows remote attackers to conduct replay attacks by sniffing the network.
Mitigation: This issue can be mitigated by one of the following methods: disabling ntpq in ntp.conf, configuring ntpd to get time from multiple sources, or using a restriction list in your ntp.conf to limit who is allowed to issue ntpq queries.

CVE-2015-8140 ntp: ntpq protocol vulnerable to replay attacks
bugzilla·2016-01-21·CVSS 4.8
CVE-2015-8140 [MEDIUM] CVE-2015-8140 ntp: ntpq protocol vulnerable to replay attacks
CVE-2015-8140 ntp: ntpq protocol vulnerable to replay attacks
The ntpq protocol is vulnerable to replay attacks. The sequence number being included under the signature fails to prevent replay attacks for two reasons. Commands that don't require authentication can be used to move the sequence number forward, and NTP doesn't actually care what sequence number is used so a packet can be replayed at any time. If, for example, an attacker can intercept authenticated reconfiguration commands that would. for example, tell ntpd to connect with a server that turns out to be malicious and a subsequent reconfiguration directive removed that malicious server, the attacker could replay the configuration command to re-establish an association to malicious server.
