NewStart CGSL MAIN 6.02 : sudo Vulnerability (NS-SA-2022-0100)

high Nessus Plugin ID 167489

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

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

 - selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
 (CVE-2021-23240)

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.
