# Aruba AOS-10 and AOS-8 controllers: buffer overflow lets adjacent attacker run code

Aruba AOS-10 and AOS-8 wireless controllers have buffer overflows in an interface that an unauthenticated attacker on the adjacent network can reach. Successful exploitation runs arbitrary code as a privileged user on the underlying operating system.

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

## Affected

- vendor:AOS-10 affected 10.8.x <= 10.8.1.1; 10.7.x <= 10.7.2.6; 10.4.x <= 10.4.1.13 fixed 10.8.1.2, 10.7.2.7, 10.4.1.14
- vendor:AOS-8 affected 8.13.x <= 8.13.3.0; 8.10.x <= 8.10.0.23 fixed 8.13.3.1, 8.10.0.24

## How to check

Run the show version command on each controller and compare against the affected ranges: AOS-10 10.8.x up to 10.8.1.1, 10.7.x up to 10.7.2.6, 10.4.x up to 10.4.1.13; AOS-8 8.13.x up to 8.13.3.0, 8.10.x up to 8.10.0.23.

## Fix

Upgrade AOS-10 to 10.8.1.2, 10.7.2.7 or 10.4.1.14, and AOS-8 to 8.13.3.1 or 8.10.0.24.

## From the sources

Buffer overflow vulnerabilities in the affected interface of AOS-10 or AOS-8 could allow an unauthenticated adjacent attacker to execute arbitrary code by sending specially crafted data to the affected interface. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
