# HPE Networking VIA client for Linux: arbitrary file write lets local users escalate privileges (fixed in 4.7.9)

The Virtual Intranet Access (VIA) client has an arbitrary file write flaw. A local user with low privileges can write files anywhere they choose and use that to gain higher privileges on the machine.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:VIA client affected <= 4.7.8 fixed 4.7.9

## How to check

Check the installed VIA client version; 4.7.8 and below is affected. Advisory HPESBNW05173 lists the VIA client as affected on all platforms, but titles this CVE as Linux, so check Linux clients first and Windows/macOS clients too.

## Fix

Upgrade the HPE Networking VIA client to 4.7.9 or later (download from networkingsupport.hpe.com).

## From the sources

An arbitrary file write vulnerability exists in the Virtual Intranet Access (VIA) client. Successful exploitation could allow a local attacker with low privileges to escalate privileges on the affected system.
