NewStart CGSL CORE 5.04 / MAIN 5.04 : sudo Vulnerability (NS-SA-2023-0029)

high Nessus Plugin ID 174100

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has sudo packages installed that are affected by a vulnerability:

 - Sudo 1.8.0 through 1.9.12, with the crypt() password backend, contains a plugins/sudoers/auth/passwd.c array-out-of-bounds error that can result in a heap-based buffer over-read. This can be triggered by arbitrary local users with access to Sudo by entering a password of seven characters or fewer. The impact could vary depending on the system libraries, compiler, and processor architecture. (CVE-2022-43995)

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.
