sol45427159: NTP authentication bypass vulnerability CVE-2016-1551
Security Advisory
Original Publication Date: 05/25/2016
Vulnerability Description
** RESERVED ** This candidate has been reserved by an organization or
individual that will use it when announcing a new security problem. When the
candidate has been publicized, the details for this candidate will be
provided. (CVE-2016-1551)
The ntpd process does not filter IPv4 bogon packets received from the network.
Impact
This vulnerability may allow unauthenticated network attackers to spoof
refclock packets to ntpd processes on systems that do not implement bogon
filtering.
Security Issue Status
F5 Product Development has assigned ID 591983 (BIG-IP), ID 594057 (BIG-IQ), ID
594059 (Enterprise Manager), and ID 507785 (ARX) to this vulnerability, and

Vulnerability Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
To mitigate this vulnerability, do not configure NTP to use a reference clock.
Additionally, you should only allow trusted users to have administrative
access to the BIG-IP system.
