NewStart CGSL MAIN 4.05 : sudo Vulnerability (NS-SA-2020-0016)

high Nessus Plugin ID 134310

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has sudo packages installed that are affected by a vulnerability:

 - In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a sudo -u \#$((0xffffffff)) command. (CVE-2019-14287)

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