NewStart CGSL MAIN 6.06 : gzip Vulnerability (NS-SA-2023-0081)

high Nessus Plugin ID 187330

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.06, has gzip packages installed that are affected by a vulnerability:

 - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. (CVE-2022-1271)

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