Summary
Multiple Cisco products incorporate a version of the Network Time Protocol daemon (ntpd) package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition or modify the time being advertised by a device acting as a Network Time Protocol (NTP) server.
On January 19th, 2016, NTP Consortium at Network Time Foundation released a security advisory detailing 12 issues regarding multiple DoS vulnerabilities, information disclosure vulnerabilities, and logic issues that may result in an attacker gaining the ability to shift a clients time. The vulnerabilities covered in this document are as follows:
CVE-2015-7973: Network Time Protocol Replay Attack on Authenticated Broadcast Mode Vulnerability
CVE-2015-7974: Network Time Protocol Missing Trusted Key Check
CVE-2015-7975: Standard Network Time Protocol Query Program nextvar() Missing Length Check
CVE-2015-7976: Standard Network Time Protocol Query Program saveconfig Command Allows Dangerous Characters in Filenames
CVE-2015-7978: Network Time Protocol Daemon reslist NULL Pointer Deference Denial of Service Vulnerability
CVE-2015-7977: Network Time Protocol Stack Exhaustion Denial of Service
CVE-2015-7979: Network Time Protocol Off-Path Broadcast Mode Denial of Service
CVE-2015-8138: Network Time Protocol Zero Origin Timestamp Bypass
CVE-2015-8139: Network Time Protocol Information Disclosure of Origin Timestamp
CVE-2015-8140: Standard Network Time Protocol Query Program Replay Attack
CVE-2015-8158: Standard and Special Network Time Protocol Query Program Infinite loop
Additional details on each of the vulnerabilities can be found in the official security advisory from NTP Consortium at Network Time Foundation at the following link: Security Notice
Cisco has released software updates that address these vulnerabilities.
Workarounds that mitigate some of these vulnerabilities may be available. The workarounds will be made present where available in the corresponding Cisco Bug ID for each affected product.
