# A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.5, Ivanti Policy Secure before version…

Ivanti Connect Secure, Policy Secure, and ZTA Gateways contain a stack-based buffer overflow in their web-facing code. An unauthenticated remote attacker can exploit it to run code on the gateway, and it is listed as exploited in the wild.

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

## Affected

- vendor:Ivanti Connect Secure, Policy Secure, and ZTA Gateways affected ? fixed ?
- vendor:ivanti connect secure affected = 22.7 fixed ?
- vendor:ivanti neurons for zero-trust access affected = 22.7 fixed ?
- vendor:ivanti policy secure affected = 22.7 fixed ?

## Fix

Apply the Ivanti updates and mitigations referenced in the CISA KEV entry, then hunt for compromise before returning the device to service.

## From the sources

Ivanti Connect Secure, Policy Secure, and ZTA Gateways contain a stack-based buffer overflow which can lead to unauthenticated remote code execution.

CISA required action: Apply mitigations as set forth in the CISA instructions linked below to include conducting hunt activities, taking remediation actions if applicable, and applying updates prior to returning a device to service.
