NewStart CGSL CORE 5.05 / MAIN 5.05 : rsync Vulnerability (NS-SA-2023-0010)

high Nessus Plugin ID 174060

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has rsync packages installed that are affected by a vulnerability:

 - 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 this issue 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.
