NewStart CGSL MAIN 6.02 : systemd Multiple Vulnerabilities (NS-SA-2024-0062)

critical Nessus Plugin ID 206847

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

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

- A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later. (CVE-2022-2526)

- A vulnerability was found in the systemd package. The systemd package does not adequately block local privilege escalation for some Sudo configurations, for example, plausible sudoers files, in which the systemctl status command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This issue presents a substantial security risk when running systemctl from Sudo because less executes as root when the terminal size is too small to show the complete systemctl output. (CVE-2023-26604)

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