NewStart CGSL MAIN 6.02 : rsync Multiple Vulnerabilities (NS-SA-2023-0006)

high Nessus Plugin ID 171703

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

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

 - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)

 - An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the rsync client target directory and subdirectories (for example, overwrite the .ssh/authorized_keys file). (CVE-2022-29154)

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