CVE-2018-7081 Explained : Impact and Mitigation

A remote code execution vulnerability in certain versions of Aruba Mobility Controllers poses a significant security risk.

Understanding CVE-2018-7081

What is CVE-2018-7081?

ArubaOS versions contain network-listening components with a vulnerability allowing remote code execution via specially-crafted IP traffic.

The Impact of CVE-2018-7081

This vulnerability enables attackers to crash processes or execute arbitrary code with full system privileges, potentially compromising the entire system.

Technical Details of CVE-2018-7081

Vulnerability Description

ArubaOS vulnerability permits remote code execution through network-listening components
Attackers can exploit this to execute arbitrary code with system privileges

Affected Systems and Versions

Aruba Mobility Controller firmware versions prior to 6.4.4.21, 6.5.4.13, 8.2.2.6, 8.3.0.7, and 8.4.0.3
