NewStart CGSL MAIN 6.02 : frr Vulnerability (NS-SA-2021-0084)

medium Nessus Plugin ID 147307

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has frr packages installed that are affected by a vulnerability:

 - ** DISPUTED ** An issue was discovered in FRRouting FRR (aka Free Range Routing) through 7.3.1. When using the split-config feature, the init script creates an empty config file with world-readable default permissions, leading to a possible information leak via tools/frr.in and tools/frrcommon.sh.in. NOTE: some parties consider this user error, not a vulnerability, because the permissions are under the control of the user before any sensitive information is present in the file. (CVE-2020-12831)

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 frr packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
