NewStart CGSL MAIN 6.02 : trousers Multiple Vulnerabilities (NS-SA-2022-0066)

high Nessus Plugin ID 160732

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has trousers packages installed that are affected by multiple vulnerabilities:

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges instead of by the tss user, it fails to drop the root gid privilege when no longer needed.
(CVE-2020-24330)

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the tss user still has read and write access to the /etc/tcsd.conf file (which contains various settings related to this daemon). (CVE-2020-24331)

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the creation of the system.data file is prone to symlink attacks. The tss user can be used to create or corrupt existing files, which could possibly lead to a DoS attack. (CVE-2020-24332)

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

Solution

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