## Overview

A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.6, Ivanti Policy Secure before version 22.7R1.4, and Ivanti ZTA Gateways before version 22.8R2.2 allows a remote unauthenticated attacker to achieve remote code execution.

## Affected

- `connect_secure < 22.7`
- `connect_secure = 22.7`
- `policy_secure < 22.7`
- `policy_secure = 22.7`
- `zero_trust_access_gateway < 22.8`
- `zero_trust_access_gateway = 22.8`

## Remediation

Upgrade past the affected range:

- `connect_secure 22.7`
- `policy_secure 22.7`
- `zero_trust_access_gateway 22.8`
