# A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.6, Ivanti Policy Secure before version…

Ivanti Connect Secure, Policy Secure, and ZTA Gateways contain a stack-based buffer overflow that lets a remote unauthenticated attacker run code. CISA lists it as exploited in the wild and tied to ransomware campaigns.

_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 22.7
- vendor:ivanti connect secure affected = 22.7 fixed ?
- vendor:ivanti policy secure affected < 22.7 fixed 22.7
- vendor:ivanti policy secure affected = 22.7 fixed ?
- vendor:ivanti zero trust access gateway affected < 22.8 fixed 22.8
- vendor:ivanti zero trust access gateway affected = 22.8 fixed ?

## Fix

Apply the mitigations and patches from Ivanti and the CISA instructions linked in the KEV entry; exact fixed versions are unknown from these sources.
