NTP mode 7 denial-of-service vulnerability

Overview

NTP contains a vulnerability in the handling of mode 7 requests, which can result in a denial-of-service condition.

I. Description

NTP mode 7 (MODE_PRIVATE) is used by the ntpdc query and control utility. In contrast, ntpq uses NTP mode 6 (MODE_CONTROL), while routine NTP time transfers use modes 1 through 5. Upon receipt of an incorrect mode 7 request or a mode 7 error response from an address that is not listed in a "restrict ... noquery" or "restrict ... ignore" segment, ntpd will reply with a mode 7 error response and log a message.

If an attacker spoofs the source address of ntpd host A in a mode 7 response packet sent to ntpd host B, both A and B will continuously send each other error responses, for as long as those packets get through.

If an attacker spoofs an address of ntpd host A in a mode 7 response packet sent to ntpd host A, then host A will respond to itself endlessly, consuming CPU and logging excessively.

II. Impact

A remote, unauthenticated attacker may be able to cause a denial-of-service condition on a vulnerable NTP server.

III. Solution

Apply an update

This issue is addressed in NTP 4.2.4p8. Please check with your vendor for an update, or you may download NTP 4.2.4p8 from ntp.org.

Configure NTP to limit source addresses

By using "restrict ... noquery" or "restrict ... ignore" entries in the ntp.conf file, ntpd can be configured to limit the source addresses to which it will respond.

Filter NTP mode 7 packets that specify source and destination port 123

In most cases, ntpdc mode 7 requests will have either a source or destination port of 123, but not both.

Use anti-spoofing IP address filters

RFC 2827 (BCP 38) describes network ingress filtering, which can prevent UDP traffic claiming to be from a local address from entering your network from an outside source. Some ISPs may employ unicast reverse path filtering (uRPF) to limit the spoofed traffic that can enter your network.

Title: DSA-1992-1 chrony -- several
Description: Several vulnerabilities have been discovered in chrony, a pair of programs which are used to maintain the accuracy of the system clock on a computer. This issues are similar to the NTP security flaw CVE-2009-3563. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2010-0292 chronyd replies to all cmdmon packets with NOHOSTACCESS messages even for unauthorised hosts. An attacker can abuse this behaviour to force two chronyd instances to play packet ping-pong by sending such a packet with spoofed source address and port. This results in high CPU and network usage and thus denial of service conditions. CVE-2010-0293 The client logging facility of chronyd doesn't limit memory that is used to store client information. An attacker can cause chronyd to allocate large amounts of memory by sending NTP or cmdmon packets with spoofed source addresses resulting in memory exhaustion. CVE-2010-0294 chronyd lacks of a rate limit control to the syslog facility when logging received packets from unauthorised hosts. This allows an attacker to cause denial of service conditions via filling up the logs and thus disk space by repeatedly sending invalid cmdmon packets. For the oldstable distribution, this problem has been fixed in version 1.21z-5+etch1. For the stable distribution, this problem has been fixed in version 1.23-6+lenny1. For the testing and unstable distribution, this problem will be fixed soon. We recommend that you upgrade your chrony packages.

Id Description
60847 NTP ntpd Mode 7 Request Crafted Packet Reply Loop Remote DoS

NTP contains a flaw that may allow a remote denial of service. The issue is triggered when ntpd processes specially crafted MODE_PRIVATE packets, and will result in loss of availability for the service.
