Network Time Protocol Daemon (ntpd) Information Disclosure

Medium Nessus Plugin ID 84288


The remote NTP server is affected by an information disclosure vulnerability.


The remote NTP server is affected by an information disclosure vulnerability due to improper validation of the 'vallen' value in extension fields in 'ntp_crypto.c'. This allows a remote attacker to disclose sensitive information.

Note that this plugin requires both the scanner IP and target IP to not go through Network Address Translation (NAT) when communicating with each other.


Upgrade to NTP version 4.2.8p1 or later.
