NewStart CGSL CORE 5.05 / MAIN 5.05 : ntp Vulnerability (NS-SA-2021-0186)

high Nessus Plugin ID 154477

Language:

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has ntp packages installed that are affected by a vulnerability:

 - ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. (CVE-2020-13817)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL ntp packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
